What is Travel Rule?
The Travel Rule is an AML regulation requiring financial institutions to transmit sender and recipient identifying information alongside cross-institutional value transfers. Applied to crypto, it means exchanges must share KYC data when users transfer between platforms.
How does Travel Rule work?
- A user initiates a withdrawal from one exchange to another.
- The sending exchange identifies the user via KYC procedures.
- Identifying information is transmitted to the receiving exchange using protocols like TRISA.
- The receiving exchange verifies the data before crediting the funds.
Why does Travel Rule matter?
It closes the anonymity gap in cross-exchange transfers, applying the same transparency standards to crypto as traditional wire transfers. Non-compliance risks heavy regulatory penalties.
Key features of Travel Rule
- Applies to custodial exchanges and centralized intermediaries
- Requires secure data sharing between institutions
- Enforcement and thresholds vary by jurisdiction
- Does not apply to self-custodied wallet transfers
Examples of Travel Rule
When a user withdraws Bitcoin from Kraken to Coinbase, Kraken must transmit KYC data to Coinbase. The EU's MiCA framework requires Travel Rule compliance on all transfers above 1000 euros.
