The Travel Rule

How the rule that sender and recipient details must travel with a payment applies to crypto transfers in the US, under FATF standards, in the EU and in the UK, and why self-hosted wallets are the hard case.

Education, not legal, tax or investment advice. Crypto law differs between countries and states and changes often. Check the current rules where you live with a qualified lawyer or tax adviser before you act.

The lean path

The cheapest, lowest-tax, simplest and most private route the law allows, best first. Each step names the rule it rests on and the condition that keeps it lawful.

  1. Transfers between self-hosted wallets carry no travel-rule duty in the US, EU or UK. Users and builders of purely peer-to-peer tools owe no data transfer, but sanctions law still applies.
  2. US providers must send travel-rule data only for transmittals of $3,000 or more (31 CFR 1010.410(f)). The 2020 proposal to cut this to $250 was never finalised, and the threshold still applies in 2026.
  3. Use an existing travel-rule messaging network rather than building your own. Data can travel off-chain, as FATF’s Interpretive Note to Recommendation 15 allows, but it must be sent before or at the time of the transfer.
  4. For EU users, Regulation (EU) 2023/1113 applies at any amount. Self-hosted addresses over €1,000 need a proof-of-control check, so a signed-message or test-transfer flow is the cheapest way to comply.
  5. FinCEN withdrew its unhosted-wallet reporting proposal on 6 October 2026, so no US report is needed for withdrawals to personal wallets, though income and gains are still reported.

Wonder

  1. Why does an exchange ask me who owns the wallet I am withdrawing to?
  2. Does the travel rule apply to a transfer from my own wallet to a friend’s wallet?
  3. Is the US threshold the same as Europe’s?

  1. The ‘travel rule’ requires a financial institution that sends a payment to pass identifying information about the sender, and some about the recipient, to the next institution in the chain, so the trail does not break. In the US it is 31 CFR 1010.410(f): for a transmittal of funds of $3,000 or more, the sender’s institution must include the sender’s name, account number and address, the amount, the execution date and the recipient’s institution, plus recipient details it has received. A companion rule requires records of the same transfers. Duties arise only for financial institutions such as money services businesses (lesson 5.2.3), not for individuals sending from their own wallets.
  2. FinCEN’s guidance FIN-2019-G001 of 9 May 2019 says a transfer instruction involving convertible virtual currency is an instruction to pay ‘a determinable amount of money’, so crypto transfers can be transmittals of funds covered by what it calls the Funds Travel Rule, at $3,000 or its equivalent in crypto. The information must be obtained or passed on before or at the time of the transfer, however the business settles transactions. A footnote adds that a business which builds a system that makes compliance difficult cannot use that difficulty as an excuse. A hosted wallet provider’s duties depend on its position in the chain: sender’s, intermediary or recipient’s institution.
  3. Two US proposals to go further did not become law. In October 2020 FinCEN and the Federal Reserve proposed cutting the threshold to $250 for transfers that begin or end outside the US and stating expressly that crypto is covered; the rule text still reads $3,000 as of October 2026. In December 2020 FinCEN proposed that banks and money services businesses keep records of crypto transfers above $3,000 involving ‘unhosted’ wallets and report those above $10,000. FinCEN withdrew that proposal, together with a 2023 proposal on crypto mixing, in a notice published on 6 October 2026, saying it would take no further action.
  4. Internationally the benchmark is the Financial Action Task Force (lesson 1.3.7). In June 2019 it adopted its Interpretive Note to Recommendation 15, applying the wire-transfer standard to ‘virtual asset service providers’ (VASPs). Originating VASPs should obtain and hold accurate originator information and required beneficiary information, send it to the beneficiary VASP immediately and securely, and make it available to authorities; the data need not be attached to the blockchain transaction itself. The same note set USD/EUR 1,000 as the threshold for checks on occasional transactions. Countries carry out the standard at different speeds, so a compliant firm may find its counterparty in another country has no matching rule.
  5. The EU applies the strictest version. Regulation (EU) 2023/1113 of 31 May 2023, applying from 30 December 2024, requires crypto-asset service providers to send originator and beneficiary information with every crypto transfer, regardless of amount and whether domestic or cross-border, because crypto values move quickly. For a transfer of more than EUR 1,000 to or from a self-hosted address on a customer’s behalf, the provider must assess whether that address is owned or controlled by its customer. In the UK, the Financial Conduct Authority said cryptoasset businesses must collect, verify and share transfer information from 1 September 2023. Licensing of EU providers is covered under MiCA (lesson 3.3.2).
  6. For users, the travel rule explains why a withdrawal to a personal wallet may trigger questions, a request to prove that you control the wallet, or a delay. For builders, it matters whenever the product is the regulated intermediary: a custodial app sending to another exchange must find the counterparty, check that it is a regulated provider, and exchange data securely, often through industry messaging networks. Purely peer-to-peer transfers between self-hosted wallets are outside these rules, although sanctions law still applies to everyone (lesson 5.2.5). A practical check: for each outgoing transfer type your product supports, write down whether the recipient is another provider, a self-hosted wallet or unknown, and which jurisdiction’s threshold applies.

Key facts

  • An October 2020 proposal by FinCEN and the Federal Reserve to lower the threshold to $250 for cross-border transfers was not finalised; the rule still states $3,000.
  • FinCEN withdrew its December 2020 unhosted-wallet proposal in a Federal Register notice published on 6 October 2026.
  • The FATF adopted its Interpretive Note to Recommendation 15, extending the travel rule to virtual asset service providers, in June 2019.
  • Regulation (EU) 2023/1113 applies from 30 December 2024 and covers crypto transfers regardless of amount.

6ClusterSort them into 6 categories: provider to provider in the US, provider to provider across borders, provider to self-hosted wallet, self-hosted wallet to provider, self-hosted to self-hosted, and transfers whose route you do not know.
3DistillReduce the 6 to 3 groups: transfers where travel-rule data must move, transfers where a provider must check who controls a wallet, and transfers outside travel-rule duties.
