Terms of Use


bitFlyer Europe S.A. is authorised in Luxembourg by the Ministry of Finance as a Payment Institution (license number Z00000016) and is registered as a Virtual Asset Service Provider (registration number 00000001) subject to the prudential and AML/CTF supervision of the Commission de Surveillance du Secteur Financier (the CSSF).

By accessing and/or using this website, you acknowledge that you have read and agree to abide by these terms described below (Terms). If you do not agree to these Terms, you should exit this site now. These Terms may be amended at any time and the amended Terms will be published on this site. Your continued usage of our services on this website or our app (Services) after the amended Terms come into effect shall constitute acceptance of such amendments.

These Terms, and your acceptance thereof, constitutes a binding contract between you and bitFlyer EUROPE S.A., a company having its registered office at 121 Rue de Hollerich, L-1741, Luxembourg, Grand Duchy of Luxembourg and registered with the Luxembourg Trade and Companies Register under number RCS Luxembourg B211897 (bitFlyer, Us, We and/or Our) and applies to your use of Our Services. These Terms incorporate, and you hereby accept and agree to, all applicable policies, notices, procedures, specifications, FAQs, guides and guidelines that are provided and/or made available to you, appear on our website and/or are referenced in these Terms and which we may modify from time to time (collectively, the Policies).


This section highlights the risks associated with crypto-assets generally and Our Services, in particular, that you should consider. By accepting these Terms, you confirm having understood and accept to bear all such risks. You are solely responsible for understanding and complying with any and all laws, rules and regulations that may be applicable to you in connection with your use of Our Services, including but not limited to, those related to AML/CTF, sanctions, taxation or foreign currency transactions, reporting and disclosure obligations and any other Applicable Laws, rules and requirements whatsoever.

Risk of Fiat Funds Not Being Immediately Available

We may close, suspend and/or limit your access to your Account and/or Our Services, or limit your access to your funds to the extent and for the duration reasonably necessary to protect Our Services from external factors including your use of Our Services, market events, any virus, worm, time bomb, Trojan horse, spyware, malware or other similar malicious software, script, bot, program and/or code that can cause harm to Our Services (Malicious Code) against the risk of breach of these Terms at our sole discretion. For the avoidance of doubt, we may also permanently block your account for any material breach of these Terms.

Please note that although you may only have one account with bitFlyer, your account has two separate and distinct functionalities: the payment functionality and the reserve functionality. Your ability to access funds in your account and to execute payment transactions from your account will depend upon which functionality the funds are subject to at any given time. For the purposes of these Terms:

The element of your account which constitutes the payment functionality will be known as the "payment account". The payment account is the operational part of your account through which you have access to your fiat funds and which can be used for the execution of payment transactions in accordance with the EU Payment Services Directive.

The element of your account which constitutes the reserve functionality will be known as the "Reserve". Your access to the Reserve is restricted and you have no ability to access funds in the Reserve and/or to execute payment transactions with funds in the reserve account. Funds held in the Reserve account may be marked or categorized, for example, as “Pending”, “Under Review”, “Risk Reserve” or another similar terminology. Examples of when funds may be temporarily held in the Reserve by bitFlyer are related to certain clearing and settlement issues, anti-money laundering, fraud, financial and other regulatory matters.

Funds held in the Reserve may, in some instances, still be used to trade on the platform, however, the Reserve amount shall remain at the same value until released from the Reserve. Any Losses you may suffer as a result of utilisation of Reserve funds shall be covered solely by you.

Payment Execution Risks

Please note that bitFlyer will endeavour execute a valid Payment Order made by you through your payment account and credit the payment service provider of the person to whom you are sending your payment as soon as the payment schemes and financial networks available to bitFlyer allow. However, such executions may be delayed due to issues with available payment networks.

Price Change Risk Associated with Using Crypto-assets

Prices of crypto-assets fluctuate day by day and also within the same day. Your crypto-asset trade or balance could surge or drop suddenly. Please note that there is a possibility that the price of a crypto-asset could drop to zero. Prices of crypto-assets are prone to significant fluctuations, for example, due to announced proposed legislative acts, governmental restrictions, news related to cyber-crimes or other factors, causing potentially excessive market enthusiasm or disproportionate loss in confidence. Prices of some crypto-assets may be manipulated.

bitFlyer shall bear no liability for any Losses sustained as a result of value fluctuation of any of the crypto-assets listed on the Exchange.

Nature of Crypto-assets and Trade Execution Risk

bitFlyer is a payment institution, therefore accounts and the value of crypto-balances you have with bitFlyer are not protected by the Luxembourg deposit guarantee fund or the Luxembourg investor compensation system administered by the Conseil de protection des déposants et des investisseurs.

Crypto-asset is not legal tender and is not backed by the government. Unlike fiat currencies, which are regulated and backed by local governments and central banks, crypto-assets are based only on technology and user consensus. In cases of massive manipulations or market panic, central governments may not take any corrective actions to guarantee stability, maintain liquidity or protect the value of a crypto-asset.

There is a possibility that certain trades cannot be executed and/or settled or may be difficult to trade and/or settle, or can be traded only at significantly adverse prices depending on the market situation and/or market volume for certain crypto-assets. Particularly during periods of high volume, illiquidity, fast movement or volatility in the marketplace, the execution price received in connection with a completed transaction may differ from the quote first provided.

There is also no assurance that a person who accepts a crypto-asset as payment today will continue to do so in the future.

Additionally, we ask that you exercise caution and use your own judgement when sending crypto assets to unregistered or unregulated crypto asset platforms who are not subject to the segregation of customer assets obligation. We will not be able to compensate for any losses incurred by you if the crypto asset platform to which you send your crypto assets misappropriates them.

You acknowledge and understand these risks and assume them as your own by continuing to utilise the bitFlyer platform. bitFlyer shall bear no responsibility in the event of any Losses suffered as a result of the volatility of the market.

Blockchain Network Risk

Certain crypto-asset transactions (transactions executed on the blockchain) can be deferred for a certain period of time until an adequate amount of confirmations have been received. Transaction results will not be reflected to your bitFlyer account balance until an adequate amount of confirmations have been received and confirmed by bitFlyer. There is a possibility that your transaction may be cancelled on the blockchain. Some crypto-asset transactions shall be deemed to be made when recorded on a public ledger, which is not necessarily the date or time when you or another party initiated the transaction.

Transactions in crypto-asset may be irreversible, and, accordingly, Losses due to fraudulent or accidental transactions may not be recoverable.

Risk of Losing the Private Key or Password of the External Wallet Services

In case you use an external wallet, you may not be able to access your crypto-asset if you lose your private key or password, with the result that your crypto-asset is permanently lost for you. bitFlyer will not be able to help you in this case.

Regulatory Uncertainty

The regulatory framework in relation to transactions with crypto-assets is still emerging. It is possible that your transactions are or may be in the future subject to various reporting, tax or other liabilities and obligations. Legislative and regulatory changes or actions at the country, regional (for example, in the EU/EEA) or international level may adversely affect the use, transfer, exchange, and value of crypto-asset.

It is your responsibility to ensure you are fully compliant with your local regulatory framework.

  1. You agree to provide accurate, current and complete information about your identity and location in connection with creating your bitFlyer account; keep your bitFlyer account information updated at all times; immediately notify us if you change your country of residency or if any other information previously provided to bitFlyer changes; not use a password for your bitFlyer account that you use for any other website or online service; protect the security of your bitFlyer account, including not sharing your Login Credentials with any third party; and immediately notify us if you discover or otherwise suspect any unauthorized access or use related to the Services or your bitFlyer account. If you do not provide all required information when opening your bitFlyer account, we reserve the right to place your account on standby and/or freeze or suspend your account until you provide all required information. We may also close your on-boarding process and delete your Personal Data if we do not receive all required information within the prescribed time frame.
  2. If you have applied for another bitFlyer account in the past with any of the same information, we reserve the right to not approve the new bitFlyer account and you may be required to access and use your previously approved bitFlyer account. If you were previously denied a bitFlyer account, or had a bitFlyer account closed by us, you may not be able to reapply for a bitFlyer account.
  3. We may require you to provide additional information to verify your or your business’ identity as a condition to providing the Services to you, or before we permit you to make payments or receive or withdraw funds from your Account. We may make, directly or through a third party, any inquiries we consider necessary to validate information that you provide to us, including without limitation checking commercial databases, population registers or credit reports. You authorize us to obtain one or more of your credit reports, from time to time, to establish, update, or renew your account with us or in the event of a dispute relating to these Terms and activity under your account.

You are solely responsible for taking appropriate steps to verify the identity of other users of the Services with whom you transact.


  1. You can review the personal or business information you have provided us and make any desired changes to such information, or to the settings for your bitFlyer account at any time, by logging into your account profile and changing your preferences. You can also terminate your Account through the bitFlyer website. If you terminate your account, we will mark your Account in our database as "Closed", but will keep your account information in our database for up to 5 years or longer, as required by applicable regulations. This may be necessary, for example, in order to deter fraud, by ensuring that persons who try to commit fraud will not be able to avoid detection simply by closing their account and opening a new account. However, if you close your Account, your personally identifiable information will not be used by us for any further purposes, nor sold or shared with third parties, except as necessary to prevent fraud and assist law enforcement authorities, or as required by Applicable Law.
  2. Unless your account access is restricted (for example, due to suspected unauthorized access or a very prolonged inactivity), you may access your details of executed payment transactions and other information relating to your account transaction history and available Funds by logging into your Account. Key information relating to your transactions or important updates will be provided to you also via e-mail. You will also be able to access a downloadable report via your account profile including all fees incurred and any other amounts charged to your Account in the relevant period. bitFlyer reserves the right to charge a fee for providing you with additional information or for providing the transaction history and other information about fees in a different way (other than via downloadable standard reports). The way in which we provide the transaction information will allow you to store and reproduce the information unchanged, for example by printing a copy. You hereby agree to receive your transactions information through your account transactional history instead of receiving periodic statements by mail.
  3. You have the right to make use of services enabling access to Account Information Service Providers or Payment Initiation Service Providers as your Account is accessible electronically.

  5. Account Information Service Providers provide their customer with aggregated online information on one or more payment accounts held with one or more other payment service providers and accessed via online interfaces of the account servicing payment service provider (such as bitFlyer).
  6. Where you decide to use a Payment Initiation Service Provider or an Account Information Service Provider, bitFlyer will:
    • communicate securely with the Payment Initiation Service Provider and the Account Information Service Provider;
    • immediately after receipt of the Payment Order from a Payment Initiation Service Provider, provide or make available all information on the initiation of the Payment Transaction and all information accessible to the Bank regarding the execution of the Payment Transaction to the Payment Initiation Service Provider;
    • treat Payment Orders transmitted through the services of a Payment Initiation Service Provider without any discrimination other than for objective reasons, in particular in terms of timing, priority or charges vis-à-vis Payment Orders transmitted directly by you.


  • In the event your account has remained inactive for a specified period, the Period of Dormancy, bitFlyer shall undertake measures for the appropriate verification and monitoring of inactivity of the account.
  • The Period of Dormancy shall be divided into two distinct time frames under which an investigation into the status of the account shall be initiated depending on the value of funds held in the account:
    • Inactivity Period: The threshold for the period of inactivity shall be 6 months since the date of your last login onto their bitFlyer account. During the Inactivity Period, bitFlyer shall make no attempt to contact you.
    • Period of Expiry: The threshold for the Period of Expiry shall be 6 months after the completion of the Inactivity Period and shall be the duration within which bitFlyer shall attempt to re-establish contact with you.
  • If at the end of the Period of Expiry no contact with you has been established, bitFlyer reserve the right to move your account into Dormancy. Where your Account holds assets (crypto-assets or Fiat funds), bitFlyer may undertake further measures to ascertain the proper allocation of the unclaimed assets in line with its regulatory obligations.
  • The threshold applied to the value of funds to determine the level of investigations carried out by bitFlyer to locate the User shall be determined as follows:
    • Up to 5,000 EUR – Where you have provided personal contact information, bitFlyer shall endeavour to contact you either by telephone, or a letter to the registered address, or both;
    • From 5,000 EUR – 10,000 EUR – Where contact has not been established using the personal information provided, bitFlyer shall utilise resources to obtain information from public directories and enhanced internet searches to contact you;
    • Above 10,000 EUR – In cases where your funds exceed 10,000 EUR and bitFlyer has failed to obtain information utilising the methods prescribed for the thresholds above, bitFlyer may hire professional assistance by specialised services and/or legal specialists to contact you.
  • All costs borne by bitFlyer for the purposes of re-establishing contact with the Client, shall be solely borne by you. The costs shall be deducted from your account and invoiced accordingly with all evidence of costs borne attached.
  • During the investigation phase, if it has been discovered that you have passed away, bitFlyer will take necessary measures in line with Applicable Laws.
  • In the event your Account has been re-activated outside of the Period of Expiry, bitFlyer reserves the right to request the re-verification of your identity for the purposes of preventing fraud in line with our internal policies.


  1. In the event of a User’s death, bitFlyer shall require proof that the heir/beneficiary is entitled to the ownership of the deceased's assets in bitFlyer's possession as well as a certified copy of the death certificate in order to access the accounts of deceased.
  2. The executor of the will and the administrator of the estate will need to prove their status to exercise their rights to obtain the User’s assets from bitFlyer. bitFlyer reserves the right to perform necessary due diligence in cases of cross-border succession for the prevention of fraud.
  3. The authority of the EU Member State overseeing the inheritance or succession process can provide the requesting heir or the executor with an official national document certifying their status as an heir, executor of the will or administrator of the estate. Alternatively, they can ask that authority to provide them with a European Certificate of Succession. The European Certificate of Succession is the same throughout the EU and applies with no special procedures regardless of the country in which it was issued. A national document on the other hand, will have different effects depending on the EU country in which it is issued and therefore for procedural purposes it is necessary for bitFlyer to ask for this certificate. Otherwise, the requester may need to have their national document recognised in Luxembourg which may delay bitFlyer's ability to release the asset's.

  2. We draw your attention on the importance to take all necessary measures and precautions to preserve security.

Granting permission to any third party in any way does not relieve you of any of your responsibilities under these Terms. You acknowledge and agree that you will not hold bitFlyer responsible for, and will indemnify bitFlyer from, any liability arising from the actions or inactions of this third party in connection with the permissions you granted. In case of loss or theft or the disclosure of any of your Login Credentials to a third party (even if involuntary or merely suspected), misappropriation or any other unauthorized use of the Services, or if your Login Credentials are otherwise compromised (an “Incident”) you must notify us immediately by using our Contact page so that we can suspend use of your Account with our Service or help you to reset your password in order to avoid unauthorized transactions.

The sole transmission to bitFlyer of a Payment Order in the above described manner shall constitute authorization of such Payment Order.

    When authorizing a Payment Order in this manner you instruct bitFlyer to execute the transaction immediately (unless otherwise stated) in accordance with your instructions and charge you any applicable Fees.

    The validation of a payment order through the use of the Services shall have the same value as your original signature and shall have the same value in evidence as an original written document.

    You expressly agree that, notwithstanding the provisions of Article 1341 of the Civil Code, bitFlyer is, whenever useful or necessary, entitled to prove its allegations by any means legally admissible in commercial matters.

    Computerized records or other records effected by bitFlyer constitute prima facie evidence of the communications between bitFlyer and you and shall have the same value in evidence as an original written document.

    You represent and warrant that any information you provide through the Services, in connection with a transaction or otherwise, is accurate and complete.

  2. Receipt of a Payment Order. A Payment Order shall be deemed to have been received by bitFlyer at the time of actual validation by you of the Payment Order, it being understood that, depending on the payments instrument used, certain Payment Orders or validation thereof received by bitFlyer after the cut-off times imposed by our banking or payments partners, or at any time during a non-Business Day, will be deemed to have been received on the next Business Day.

    For all other Payment Transactions effected within the EEA other than the Payment Transaction described in the preceding paragraph, bitFlyer will ensure that the amount of the Payment Transaction is credited to the account of the Payment Service Provider of the Payee by no later than the fourth Business Day following the moment of receipt of the Payment Order in accordance with these Terms.

    For all other Payment Transactions not covered in the preceding paragraphs, you acknowledge that the execution time for the Payment Transaction will be subject to the operating rules of international payment systems and that in this case, we will not be bound by the deadlines set out above.

    In the event we do not detect a fraudulent use or misuse of your Login Credentials (including strong authentication, as applicable) and execute a Payment Transaction initiated through such Login Credentials, we shall, except in the case of gross negligence or wilful misconduct, be deemed to have validly executed the Payment Transaction, as if the Payment Transaction had been initiated by you.

  3. Restrictions. We may, at any time, refuse an order submitted via the Services, or impose any other conditions or restrictions upon your use of the Services. The reasons for the refusal and the procedure for correcting any factual mistakes that led to the refusal will be notified to you at the latest by the end of the Business Day following the refusal. bitFlyer will be deemed to have satisfied this obligation if it has sent the notification of refusal within the period of execution time regardless of the date of actual receipt by you of such notification. Any notification by bitFlyer of a justified refusal of a Payment Order may result in you being charged a fee.

    bitFlyer may, without being obliged to do so, refuse to execute a Payment Order:

    • if the Payment Order contains any factual error, in particular, incomplete or imprecise transactional details;
    • if you have breached any of your obligations towards bitFlyer under these Terms or any other agreement entered into between you and bitFlyer;
    • if the Payment Order does not meet the agreed form as set out in these Terms;
    • if your Funds are insufficient to execute a Payment Order in full;
    • if the spending limits as may have been agreed upon between you and bitFlyer have been reached;
    • if the Payment Order cannot be executed in full;
    • if the Payment Order has been made by a person who has no power to operate the Account and this is apparent to us without the need to conduct any investigations;
    • if bitFlyer is legally or contractually obliged to freeze your Account or block transactions;
    • if bitFlyer suspects that the security of Service is compromised, e.g. because of a problem or technical failure or because of hacking attacks;
    • if bitFlyer suspects fraud (for example where it has identified suspicious transaction(s)) or has received notification that an incident has occurred);
    • if bitFlyer believes that the execution of the Payment Transaction would be contrary to any national or foreign laws, regulations or decisions of authorities or would expose bitFlyer to any liability or Claim whatsoever.

    Should you elect to proceed with the execution of a Payment Order notwithstanding refusal thereof by bitFlyer, you shall provide bitFlyer with a new Payment Order containing all the required elements. It will not be possible to correct the initial Payment Order, which was refused by bitFlyer.

    bitFlyer may deny an Account Information Service Provider or a Payment Initiation Service Provider access to a Payment Account for objectively justified and duly evidenced reasons relating to risks of unauthorized or fraudulent access to the Account by that Account Information Service Provider or that Payment Initiation Service Provider, including the unauthorized or fraudulent initiation of a Payment Transaction.

    bitFlyer will inform you that access to the Account is denied and the reasons therefore. That information shall, where possible, be given to you before access is denied and at the latest by the end of the Business Day following the refusal , unless providing such information would compromise objectively justified security reasons or is prohibited by other Applicable Law.

    In the event of a Payment Order which is beyond your Account’s permissible use or applicable limits, bitFlyer may request additional identifying information from you and must receive such information before processing the Payment Order. If you fail to provide this additional required information or documentation, the attempted transaction may be refused or suspended by bitFlyer, without being obliged to do so.

  4. Insufficient Customer Balance. If you have insufficient Funds on your Account to complete a Payment Order (this also include instances of insufficient balance with respect to the asset category specified in your Payment Order), we may cancel the entire Payment Order or we may fulfil a partial Payment Order using the amount of Funds currently available in your Account, less any fees.
  5. Cancellations. You may not revoke a Payment Order once it has been received by bitFlyer. Such Payment Order will be executed by bitFlyer notwithstanding any subsequent revocation order by you.
  6. Where a Payment Transaction is initiated by a Payment Initiation Service Provider or by or through the Payee (e.g. where the payment order is issued in execution of a direct debit order), you may not revoke the Payment Order after transmitting the Payment Order or giving your consent to the Payment Initiation Service Provider to initiate the Payment Transaction or after giving consent to the execution of the Payment Order to the intended Payee.

    bitFlyer may, but shall not be obliged, to accept the revocation of a Payment Order re-quested by you after receipt of such Payment Order. bitFlyer may not be held liable for not having exercised such right. Should bitFlyer accept a revocation after receipt of the Payment Order, it is entitled to charge you a fee.

  7. No Returns or Refunds for Blockchain-based transactions. All blockchain-based transactions are final and non-reversible. We do not accept any returns or provide refunds in connection with any such transactions under any circumstances whatsoever.
  8. Crypto-asset Transactions. While a crypto-asset transaction is pending confirmation by the applicable network, the crypto-asset subject to such confirmation will be unavailable for use in connection with any other Services transaction.
  9. Cancellation of Transaction. If it can reasonably be assumed that there is an error in the asking price, such as a major discrepancy with market rates, the asking price may be invalidated and the transactions based on that asking price may be cancelled by bitFlyer, without obligation for bitFlyer to do so. bitFlyer also reserves the right to halt trading, without being obliged to do so. bitFlyer may not be held liable for not having exercised such rights.
  10. Supported Crypto-Assets. It is your sole responsibility to verify the types of crypto-assets bitFlyer will accept (“Supported crypto-assets ”). Any other (“Unsupported crypto-assets”) crypto-assets sent to bitFlyer may be lost, destroyed or not returned to you. Additionally, there may be fees charged if bitFlyer attempts to retrieve the Unsupported crypto-assets to return them to you. bitFlyer shall, however, have no obligation to make such attempts. The sending, depositing, and returning of Unsupported crypto-assets puts you at risk of loss of such crypto-assets. bitFlyer accepts no liability for unsupported crypto-assets sent to bitFlyer under any circumstances whatsoever.
  11. Blockchain Modification, Disruption or Hard Fork. In the event of a change in the structure of a blockchain such as a hard fork or chain split, or in the event of an occurrence such as an airdrop, whether or not to take response measures and what measures to take will be at the sole discretion of bitFlyer. bitFlyer does not bear any liability in the event that you or a third party incur Losses as a result of the defects, alteration, or lack of measures taken by bitFlyer or if bitFlyer decides to cease handling a crypto-asset in whole or in part.
  12. Lack of Identifying Account Information. In the event of an order which is beyond your account’s permissible use or applicable limits, bitFlyer may request additional identifying information from you and must receive such information before processing the order. If the you fail to provide this additional required documentation, the attempted transaction may be suspended.
  13. Unclaimed Assets. If bitFlyer is holding Funds in your Account, and we are unable to contact you and have no records of your use of the Services for a prolonged time, bitFlyer will try to locate you at the last available address in our records . If bitFlyer is unable to locate you, you agree that bitFlyer may report these Funds to authorities and deliver any such Funds to relevant authorities, such as the Caisse de Consignation. bitFlyer reserves the right to deduct Fees from such unclaimed Assets in accordance with clause 6 of these terms.
  14. Any Claim with respect to the unauthorized or defective execution of a Payment Transaction referred to in your transaction history or other reports or the non-execution of a Payment Transaction must be submitted by you to bitFlyer in writing within 30 days of the execution or non-execution of the Payment Transaction. In the absence of any Claim lodged before the expiration of the aforementioned period, you will be deemed to have authorized such Payment Transactions, which shall be considered as definitively accepted by you.
  15. Unauthorized Payment Transactions (in case a Claim is lodged within the time specified in Section 8.14). If a Payment Transaction was not authorized by you, bitFlyer shall refund you the amount of the relevant Payment Transaction no later than the end of the following Business Day after noting or being notified of the transaction and, where applicable, restore the debited Account to the state in which it would have been, had the unauthorized Payment Transaction not occurred. However, this obligation shall not apply where bitFlyer has reasonable grounds for suspecting fraud and communicates those grounds to the relevant national authority in writing.

    Where the payment transaction is initiated through a payment initiation service provider, bitFlyer shall refund, no later than by the end of the following business day the amount of the unauthorised payment transaction and, where applicable, restore the debited payment account to the state in which it would have been had the unauthorised payment transaction not taken place.

    If the payment initiation service provider is liable for the unauthorised payment transaction, it shall immediately compensate Us for the Losses incurred or sums paid as a result of the refund to the payer, including the amount of the unauthorised payment transaction. In accordance with Article 72(1) of the EU Payment Services Directive, the burden shall be on the payment initiation service provider to prove that, within its sphere of competence, the payment transaction was authenticated, accurately recorded and not affected by a technical breakdown or other deficiency linked to the payment service of which it is in charge.

    You shall, however, remain liable for any Losses resulting from an unauthorized Payment Transaction under the following circumstances and subject to the following conditions:

    1. up to a maximum of EUR 50, resulting from the use of a lost or stolen payment instrument or from the misappropriation of a payment instrument, except if:
      • the loss, theft or misappropriation of a payment instrument was not detectable to the payer prior to a payment, except where the payer has acted fraudulently; or
      • the loss was caused by acts or lack of action of an employee, agent or branch of a payment service provider or of an entity to which its activities were outsourced.
    2. If you disclosed your Login Credentials resulting in the unauthorised Payment Transaction with intent or gross negligence. In such cases, the maximum limit under clause 8.15(i) above shall not apply;
    3. you shall not bear any financial losses where bitFlyer does not require strong customer authentication, unless you have acted fraudulently.
    4. You shall not bear any financial consequences resulting from fraudulent or unauthorized use of the lost, stolen or misappropriated Credentials after you have duly notified bitFlyer except where you have acted fraudulently.

      In any case, you shall bear the entirety of the Losses resulting from an unauthorized Payment Transaction in the event that you have acted fraudulently, irrespective of the notification of an Incident sent to bitFlyer.

    5. If your account with bitFlyer is a Business Account, please, refer to clause 2.5. for additional information on applicability of certain provisions to Business Account customers.
  16. As required by Applicable Laws, bitFlyer will notify you in the event of suspected or actual fraud or security threats via your registered e-mail, phone number or mobile app notification.
  17. Non-execution or defective execution of authorized Payment Transactions (in case a Claim is lodged as defined in clause 8.14).

    You act in the capacity of Payer with bitFlyer

    1. Payment order initiated by you with bitFlyer

      In the event of a non-execution or a defective execution of a Payment Transaction, and regardless of the possibility for bitFlyer to be held responsible for such non-execution or defective execution, bitFlyer will, upon your express request, and without incurring any liability in relation thereto, endeavor to trace the Payment Transaction and to notify you of the result of such tracing.

      bitFlyer shall not be held liable for the defective execution of a Payment Order if it can establish that the amount indicated in the Payment Order has been received by the Payee’s Payment Service Provider within the required execution time.

      In the event that bitFlyer is liable for the non-execution or defective execution of a Payment Transaction, it shall, if applicable, refund you with the total amount of the Payment Transaction and, where applicable, restore the debited Account to the state in which it would have been, had the wrong Payment Transaction not taken place. In the event the collection of Funds is not possible, bitFlyer will provide you, upon written request, all information made available to bitFlyer and relevant to you in order for you to file a legal claim to recover the Funds.

      To the extent possible, bitFlyer may also take steps to correct the wrongful execution of any Payment Order, if the Payment Order contains all the indications allowing bitFlyer to remedy such wrongful execution, in particular in case the amount transferred was different from the amount indicated in the Payment Order.

      You shall have no right to request to be refunded the amount of a Payment Transaction under the conditions set forth above in the case of a late execution of a Payment Order but may have the right to the refund of the fees, charges and/or interest to which you have been subject because of such late execution.

    2. Payment order initiated by the Payee (including instances where the Payee account may be your account with another financial or payments institution)

      In the event of non-execution or defective execution of a Payment Transaction, subject to proof by you of the Payee’s Payment Service Provider having correctly transmitted the Payment Order within the required time frame, bitFlyer shall refund you the total amount of the Payment Transaction and, if applicable, restore the debited Account to the state in which it would have been, had the wrong Payment Transaction not taken place.

      To the extent possible, bitFlyer may also take steps to correct the defective execution of a Payment Order, if the Payment Order contains all the indications allowing bitFlyer to remedy such wrongful execution, in particular in case the amount transferred was different from the amount indicated in the Payment Order.

      You shall have no right to request to be refunded the amount of a Payment Transaction under the conditions set forth above in the case of a late execution of a Payment Order but may have the right to the refund of the fees to which you have been subject because of such late execution.

    3. Payment initiation services

      Where a Payment Order is initiated by you through a Payment Initiation Service Provider, bitFlyer shall refund to you the amount of the non-executed or defective Payment Transaction and, where applicable, restore the debited Account to the state in which it would have been had the defective Payment Transaction not taken place.

      If the Payment Transaction is initiated through a Payment Initiation Service Provider, the burden shall be on the Payment Initiation Service Provider to prove that within its sphere of competence, the Payment Transaction was authenticated, accurately recorded and not affected by a technical breakdown or other deficiency linked to the payment service of which it is in charge.

    You act in the capacity of Payee with bitFlyer

    1. Payment Order executed in accordance with the Unique Identifier

      A Payment Order is deemed duly executed by bitFlyer when it is executed in accordance with the Unique Identifier information provided to bitFlyer as a part of the Payment Order, notwithstanding the fact that you may have supplied bitFlyer with any additional information.

      If the Unique Identifier you provide to bitFlyer is wrong, bitFlyer will not be held liable for any damages which could result from the non-execution or defective execution of a Payment Order so long as bitFlyer has executed the Payment Order in accordance with the indicated Unique Identifier. You shall have sole responsibility to challenge the Payer and/or the Payer’s Payment Service Provider in this respect.

    2. Payment Order initiated by the Payer (including instances where the Payer account may be your account with another financial or payments institution)

      BitFlyer may be held liable for the non-execution or defective execution of a payment order for which the bitFlyer customer is the Payee only subject to proof by the customer of receipt by bitFlyer within the required time of the amount mentioned in the payment order initiated by the Payer and that such amount has not been credited to the Payee payment Account after deduction, if applicable, of the fees charged by bitFlyer.

      In such case, bitFlyer shall ensure that the amount of the payment transaction is made available to the customer in his payment Account as soon as possible and, where applicable, credit the payment Account with the corresponding amount.

      You hereby agree that, should bitFlyer be required to effect a refund in respect of a payment transaction initiated by a Payer, bitFlyer shall be irrevocably authorized to debit the amount requested by the Payer’s Payment Service Provider in such context from the payment Account, without having to make any prior inquiry with regard to the legitimacy of the refund request sent by the Payer to his Payment Service Provider. You have sole responsibility to directly challenge the Payer and/or the Payer’s Payment Service Provider with regard to the legitimacy of the Payer’s refund request.

    3. Payment Order initiated by you as Payee with bitFlyer

      bitFlyer is only liable towards you for the correct transmission of the Payment Order to the Payer’s Payment Service Provider and the execution of the Payment Transaction in accordance with the terms of these Terms and Conditions. bitFlyer shall not incur any liability in the case of non-execution or defective execution of a Payment Order if it has fulfilled these obligations.

      Notwithstanding the above, and regardless of the possibility for bitFlyer to be held responsible for the non-execution or defective execution of a Payment Order, bitFlyer will, upon your express request, and without incurring any liability in relation thereto, endeavor to trace the Payment Transaction and to notify you of the result of such tracing.

  18. Intermediaries. When Intermediaries or other Payment Service Providers are involved in the execution of a Payment Order, bitFlyer only takes responsibility for the non-execution or defective execution of a Payment Order by an Intermediary which is chosen by bitFlyer. bitFlyer shall under no circumstances be liable for actions taken by any other intermediaries.


  1. Responsibility. You are solely responsible for your use of any External Account, and you agree to comply with all terms and conditions applicable to any External Account. bitFlyer is not responsible for any External Account, for any fees charged in connection with any transaction or for the management and security of any External Account. If your External Account is subject to a breach, you understand this is outside of bitFlyer’s control and responsibility and you may only seek damages from the External Account provider based on your agreement with the External Account provider.
  2. Sending Funds to an External Account. You may send your Funds from your bitFlyer Account to an External Account that you have linked or registered via the Services. The amount of Funds you may send will be limited to the total amount of Funds that are not in Reserve and in excess of any minimum balance requirements (including as necessary to satisfy open orders you have created), less any Fees.
  3. Timing. The time needed to complete an External Account transaction will depend in part upon the performance of third parties (including the party responsible for maintaining the applicable External Account), and bitFlyer makes no guarantee regarding the amount of time it may take to complete such transactions.
  4. Rejected Transactions. In some cases, the External Account may reject a transaction or may otherwise be unavailable. You agree that bitFlyer will not be responsible for such rejected transactions or unavailability.


  1. This Section applies only when you use the Services to trade Crypto-asset for Legal Tender, or to trade one form of Crypto-asset for another form of Crypto-asset, with another User. The current name for the bitFlyer trading platform is “bitFlyer Lightning,” although we reserve the right to change this name from time to time.
    1. Hold on Customer Assets. When you open a trade order through the Services, the corresponding amount of your Assets required to complete such order, including any applicable Fees, will be held for purposes of completing the order and restricted from further activity via the Services unless the order is cancelled. Clause 8 applies in relation thereto.
    2. Settlement. Subject to these Terms of , bitFlyer will settle completed trades on a spot basis. The assets receivable in connection with a completed trade will be settled into each corresponding bitFlyer account.
    3. Independent relationship. You acknowledge and agree that: (a) bitFlyer is not acting as your broker, intermediary, agent, or advisor or in any fiduciary capacity, and (b) no communication or information provided to you by bitFlyer shall be considered or construed as investment or financial advice. Notwithstanding the foregoing, inasmuch as the bitFlyer Lightning trading platform is operated by our parent company, bitFlyer, Inc. (in Japan), we act on your behalf when placing orders on the platform.
  2. This clause applies only when you use the Services to purchase or sell crypto-asset directly from or to bitFlyer. The current name for our direct purchase and sale platform is “bitFlyer Market,” although we reserve the right to change this name from time to time.
    1. Prices and Availability. All prices reflect the exchange rates applicable to the purchase of crypto-asset using the Legal Tender or using another crypto-asset as identified in your order. All crypto-asset sales by us are subject to availability, and we reserve the right to discontinue the sale of a crypto-asset without prior notice.
    2. Quotes. Prior to completing your purchase or sale of crypto-asset, we will show the amount of crypto-asset you intend to purchase or sell and the amount of crypto-asset or other assets (e.g. fiat funds) you will pay or receive in connection with the transaction. You agree to comply with any terms and conditions provided within such notice in order to complete your transaction.
    3. Payment Methods. You may be able to purchase crypto-asset from us using an external payment method that is accepted via the Services. You represent and warrant that you are authorized to use your designated payment method for that purpose. You authorize us, or our designated payment processor, to charge your designated payment method for the full amount of the order. If the payment method you designate cannot be verified, is invalid or is otherwise not acceptable, your order may be suspended or cancelled automatically.


If you use our Services in connection with the purchase or sale of goods or services, you acknowledge and agree that we have no control over, or liability for, those transactions, including for the quality or legality of such goods or services. You must ensure that any information you transmit to third parties (including other users of our Services) in connection with any payment you make or receive via our Services is accurate and not misleading.


  1. You agree to pay the applicable fees listed on our Fee Schedule (“Fees”) to us, whenever you use our Service. bitFlyer will notably disclose to you the charges connected to the manner in and frequency with which information is provided or made available. Subject to the terms of these Terms, we reserve the right to change our Fees at any time. Fees are assessed against the amount of the transactions, including all applicable charges.
  2. Setting off. You authorize us, or our designated payment processor, to charge or deduct any applicable Fees owed in connection with orders you complete via the Services from the Funds held in your Account. You agree that we may set off against your Account balance or debit your bank account or other payment instrument connected to your bitFlyer account, as the case may be, any amounts you owe us under these Terms, including without limitation any Chargebacks, or any other Fees (“Deductions”). All Deductions are charged at the time we process a transaction and are deducted first from the collected funds and thereafter from your balance. If you owe us an amount that exceeds your balance, we may charge or debit a payment instrument registered in your account or you will pay us the full amount of the outstanding Deductions upon receipt of our invoice. You will be liable for and pay us upon presenting an invoice all costs associated with collection in addition to the amount collected, including without limitation attorneys’ fees, court costs, collection agency fees, and any applicable interest. In simple terms, our right to set-off means that we may deduct such fees, charges or other amounts mentioned in this clause from an account balance held or controlled by you. Where the aggregate amount you owe us exceeds the amount held in your Account we may show your account balance in negative figures as a reflection of the net amount you owe to us.
  3. Processing Errors. In the event there is an error in the processing of any Payment Transaction, you authorize us to initiate debit or credit entries to your Account or your bank account or another payment instrument, as applicable, to correct such error. If we are unable to debit the bank account or another payment instrument connected to your bitFlyer account, for any reason, you authorize us to resubmit the debit, plus any applicable fees, to any other bank account or payment instrument that you have on file with us (or, in the case of any fees that are owed under these Terms, to deduct such amounts from your balance).
  4. Currency Conversion. Where a currency conversion is offered by bitFlyer to you when you make your transaction, you will be shown the exchange rate (which may include the currency conversion fee) that will be applied to the transaction before you proceed with authorizing the payment transaction. By proceeding with your authorization of the payment transaction you are agreeing to the currency conversion on the basis of the exchange rate shown to you, including applicable fees. In certain cases, you will be required to elect the currency conversion service offered by bitFlyer or by another Payment Service Provider (for example, your bank) before you complete your payment by selecting one of the available conversion options. Where a currency conversion is offered by another Payment Service Provider (for example, your bank) and not by bitFlyer, and you choose to authorize the payment transaction on the basis of the exchange rate and charges offered to you by another service provider, bitFlyer has no liability to you for that currency conversion. Where your payment account is funded by a payment instrument in a different currency and therefore involves a currency conversion by bitFlyer or if you receive a payment in a currency other than the primary currency of your account from anyone, the amount received by you will be converted into the primary currency of your account at the time the payment is received, and by entering into these Terms you consent to and authorize us to do the conversion for these cases.
  5. Taxes. You are responsible for determining and paying any and all taxes and duties, including without limitation, sales, use, transfer, value added, withholding, and other taxes and/or duties assessed, incurred, or required to be collected, paid, or withheld for any reason in connection with any request for or performance or use of the Service, your use of the website, the sale or purchase of any products or services, or otherwise in connection with any action, inaction, or omission by you or any affiliate of yours, or any of your or their respective employees, agents, contractors, or representatives. You also are responsible for collecting, withholding, reporting, and remitting correct taxes and duties to the appropriate authority. While we may provide you a means for you to determine and apply taxes to your transactions (including certain automated reporting tools), we are not obliged to determine whether taxes or duties apply and are not responsible for calculating, collecting, reporting, or remitting any taxes or duties to any authority arising from any transaction.

  2. Without limiting the foregoing, in no event will bitFlyer or any of bitFlyer Parties be liable to you for any failure or delay by us (or our employees, agents, or representatives) in performing our obligations under these Terms, where such failure or delay is caused by abnormal and unforeseeable circumstances beyond our control, such as e.g. interruptions or unavailability of telecommunication systems or more generally of our Service (e.g. due to fire or similar disasters, power cuts, failure of computer systems or attacks against the systems of bitFlyer). bitFlyer shall not be liable for damages resulting from the implementation of legal provisions, measures taken by public authorities, declared or imminent, acts of war, revolutions, civil wars, fait du Prince, strikes, lockouts, boycotts and picketing, regardless of whether bitFlyer is itself a party to the conflict or if its services are only partially affected or where a failure or delay occurs as a result of bitFlyer complying with its legal obligations or national of foreign laws or regulations or decisions of authorities.

If such construction is not possible, the provision will be severed from these Terms and all remaining clauses will remain in full force and effect.

All disputes shall be of the exclusive competence of the Courts of Luxembourg, Grand Duchy of Luxembourg, unless bitFlyer chooses to bring an action against you before any other court having jurisdiction under ordinary rules of procedure, in particular according to the applicable jurisdiction rules of the relevant European regulation or applicable convention.
