Rules
The travel rule: what happens to your data on a transfer?
The European Transfer of Funds Regulation, commonly known as the 'travel rule', requires crypto service providers to share certain data about sender and recipient with a transfer. This rule already existed for bank transfers and has been extended to crypto transfers to combat money laundering and terrorist financing. This guide explains exactly what data is involved, when the rule applies, and what changes when you transfer to your own wallet.
What data is exchanged
For a transfer between two crypto service providers, the sending party must include data about the sender, such as name and account number or wallet address, and for larger amounts additional identifying information. The receiving provider must verify this data before finalising the transaction.
This data exchange takes place between the providers themselves, not publicly on the blockchain. The blockchain transaction remains visible as usual with addresses, but the link between an address and an identified person is recorded by the providers involved.
- Sender's name and account or wallet details
- Identifying data about the recipient
- Verification by the receiving provider before processing
When the travel rule applies
The rule applies to transfers between licensed crypto service providers, regardless of amount; smaller transactions can use a lighter data set, while larger amounts require more verification. Exact thresholds and implementation details can be set by each supervisor within the European framework.
The rule applies not only between two accounts at different providers, but also when transferring from a provider account to an address not belonging to a provider, such as a self-custody wallet. In that case the provider must collect additional information about the purpose and owner of that address, depending on the amount and risk profile of the transaction.
Transfers to a self-custody wallet
When you transfer crypto to a wallet you control yourself, without another provider involved, the sending party may ask you to confirm that the address is indeed yours and to provide additional information about the purpose of the transfer. This is a direct consequence of the travel rule, not an arbitrary requirement from the provider.
For users this sometimes means extra steps when transferring to your own hardware or software wallet, especially for larger amounts. If you refuse to provide this information, the provider can delay or refuse the transaction in line with its legal obligations.
- Confirmation that a self-custody address belongs to you
- Possible additional questions about the purpose of the transfer
- Refusing to provide information can lead to delay or rejection
What the travel rule does not do
The travel rule does not make blockchain transactions publicly traceable to a name for anyone viewing the blockchain; the link between address and identity stays with the providers and supervisors involved. Nor does the rule prevent you, entirely outside any provider, from transferring between two of your own wallets without any data being exchanged.
Frequently asked questions
Does the travel rule apply to every crypto transfer?
It applies where at least one side is a licensed crypto provider. Transfers purely between two self-custody wallets without a provider involved fall outside it.
Why does my platform ask for info on a transfer to my own wallet?
That's a travel rule requirement: the provider must establish that the receiving address really belongs to you and why you're sending the funds.
Does the travel rule make my name visible on the blockchain?
No, the blockchain itself shows no names. The link between address and identity is recorded by the providers, not in the public transaction data.
Can a platform refuse my transfer under the travel rule?
Yes, if required data is missing or cannot be verified, the provider can delay or refuse the transaction to meet its legal obligation.
