What to Do If Your Crypto Is Blocked Due to AML Risk: A Step-by-Step Guide

If your cryptocurrency has been blocked due to AML risk, first document the reason for the restriction and do not try to bypass it through new wallets or mixers. Then prepare proof of funds, complete the requested verification, and submit a structured appeal to the service.

What an AML-related cryptocurrency block means

An AML-related cryptocurrency block is a restriction on a transaction, withdrawal, or access to assets due to concerns about the origin of funds or the route taken by a transaction. It may occur on an exchange, crypto exchange service, custodial wallet, or payment service following an automated or manual review.

A high AML risk score does not prove that the owner has committed a crime. The score may take into account direct and indirect links between an address and sanctions lists, hacks, fraud, darknet services, and mixers. For an initial check of sanctions matches, you can use, for example, an AML risk assessment of a cryptocurrency address, while searches against sanctions lists are available through the OFAC Sanctions List Search.

It is important to determine exactly what has been blocked:

• the transaction — the transfer is not processed, or the funds are held pending review;
• the account or wallet — withdrawals, trading, or access to assets are restricted.

The appeal process and required documents may differ in these cases. Virtual asset service providers apply anti-money laundering and counter-terrorist financing procedures; transfers of certain crypto-assets may also require accompanying information under EU Regulation 2023/1113.

Why the cryptocurrency was blocked: identifying the source of the risk

First, ask the service for the exact status of the transaction. It may be an unprocessed transaction, a frozen withdrawal, an account restriction, a KYC request, or an additional AML review. The reason determines what you should do next: a technical error cannot be challenged in the same way as a high AML risk score.

Save all relevant information before contacting support:

• the TXID, network, amount, and date of the transaction;
• the sender’s and recipient’s addresses;
• the blocking notification and correspondence with the service.

Check the addresses and transaction using an independent AML scanner. This will help you determine whether the risk is associated with the wallet itself or arose from earlier transfers in the chain. Also check separately whether the address is linked to sanctions restrictions; you can use the OFAC Sanctions List Search for this purpose.

Check for technical causes as well: a network error, an incorrect tag or memo, an unconfirmed deposit, or a mismatch in the owner’s details. Virtual asset service providers apply anti-money laundering and counter-terrorist financing procedures; information about the sender and recipient may be requested for transfers. Therefore, an AML-related cryptocurrency block does not always indicate a violation — sometimes the service simply needs to verify the route and origin of the funds.

Step-by-step process for unblocking a crypto wallet

1. Do not try to bypass the restriction. Do not send the assets to a new address, use mixers or bridges, or split the funds into a series of small transfers. Such actions make it more difficult to review and explain the origin of the funds.
2. Respond through the service’s official channel. Ask which specific information is required for the review: details about the transaction, counterparty, source of funds, or purpose of the transfer. Request a case reference number and review the AML/KYC verification guide.
3. Collect documents related to the transaction. Prepare purchase records, exchange statements, information about the sale of the asset, contracts, and proof of income or inheritance. Do not send unnecessary documents: the materials should directly explain the source of the funds.
4. Create a transaction timeline. Specify the original source, transaction dates and amounts, and the sender’s and recipient’s addresses. Match each stage to a TXID so that the reviewer can follow the movement of the funds step by step.
5. Request a second review. Submit your explanation and attachments as one complete package, and keep the case number, copies of the files you sent, and the support team’s replies. If the service conducts sanctions-list screening, the information can also be cross-checked through the OFAC Sanctions List Search.

What proof of funds to prepare

Collect documents that link the source of the money, the transaction, and the specific crypto-assets. This package helps the service carry out a source-of-funds check and understand the economic purpose of the transaction.

• Exchange purchase: account details, proof of funding, and trading and withdrawal history. If the service has requested a bank or payment statement, attach a document showing the dates, amounts, and payment descriptions.
• P2P transaction: information about the counterparty and listing, proof of payment, correspondence, and documents explaining the purpose of the transaction. It is important to show the link between the money transfer, the cryptocurrency received, and the sending address.
• Income from employment, business, or the sale of property: a contract, invoice, payment document, or another source that links the income to the crypto-assets purchased or received.

Files must be clear and consistent: check that dates, amounts, networks, addresses, and TXIDs are written consistently. It is better to explain any discrepancies in advance in a separate note.

Do not send your seed phrase, private key, or password. Also do not disclose unnecessary personal data: secrets that provide access to the wallet are not needed to prove the source of funds.

How to challenge the decision and avoid being blocked again

Write your appeal without emotional language. Include your account ID, TXID, wallet address, the nature of the restriction, the source of the funds, and a specific request: complete the review, unblock withdrawals, or explain the next steps. Attach documents supporting the transactions and keep a copy of the correspondence.

If you receive a generic response, ask for the case to be referred to a compliance specialist and clarify which specific information led to the “high AML risk” status. Virtual asset service providers apply anti-money laundering and counter-terrorist financing procedures, so the review may take into account information about transfers and related addresses.

Do not forge documents or alter the transaction history. Inconsistencies in dates, amounts, payment descriptions, or the transfer route can increase suspicion and lead to additional restrictions.

After the decision, find out what source of risk was identified and stop interacting with addresses or counterparties associated with it. If there are signs of theft, fraud, or extortion, document the incident separately: save the correspondence, TXIDs, and notifications. You can use the steps to take after a cryptocurrency hack or theft when preparing such a report. An AML review does not replace an investigation, so contact law enforcement if necessary.

What to do right now: a practical checklist

1. Document the situation: take screenshots of the notification, correspondence with the service, and the transaction status. Copy the TXID and check that it belongs to the correct network rather than another transaction involving a similar address.
2. Check the sender’s address, recipient’s address, and the transaction itself using an AML tool. Do not connect your wallet to it or share private keys, your seed phrase, or access codes. If necessary, separately check for matches against sanctions lists through the OFAC Sanctions List Search.
3. Create one folder containing proof of funds: statements, documents related to the sale of an asset, and records from the exchange or payment service. In a separate file, prepare a transfer timeline including the transaction date, network, address, amount, and purpose.
4. Send one clear, consistent support request through the official website. Include the TXID, address, network, and a brief explanation of the source of funds. Attach only relevant documents and ask the service to confirm receipt of your request. Before sending it, check the AML screening of a cryptocurrency address so that you can describe the subject of the dispute more precisely.
5. Until the review is complete, do not split the funds, send them through a mixer, or give access to intermediaries. Do not trust promises to unblock cryptocurrency in exchange for an upfront payment: such offers may result in further losses.
6. For future transactions, check the counterparty’s address and the transaction in advance, and keep documents proving the source of funds.
