Travel Rule Overview

The Travel Rule requires Virtual Asset Service Providers (VASPs) to share originator and beneficiary information for qualifying transactions. With Notabene, Sumsub, or GTR, Fireblocks screens the transaction against your Travel Rule policy and the provider sends the data to the counterparty VASP; TRUST lets you prove that you own your addresses. Available on Developer Sandbox, Testnet, and Mainnet workspaces. Transfers to connected exchanges and on/off-ramp orders do not use these providers; see Exchanges Travel Rule Overview and On/Off-Ramps.

Providers

Provider	How you integrate	Enablement and connection
Notabene	Validate and encrypt the Travel Rule data, then attach it to the outgoing transaction.	Fireblocks Support enables it; you connect it in the Console.
Sumsub	Create an encrypted Travel Rule message, then link it to the transaction.	Fireblocks Support enables it; you connect it through the API, with Sumsub auto-connect.
GTR	Create an encrypted Travel Rule message, then link it to the transaction.	Fireblocks Support enables it; you connect it through the API with your GTR API key and secret.

Limitations

Combining providers: Sumsub and GTR can be active on the same workspace; Notabene cannot run alongside Sumsub or GTR. TRUST works alongside any provider.
Encryption: with Notabene, Sumsub, and GTR you encrypt the PII on your side, so Fireblocks never holds the keys to decrypt it.
TRUST has no screening policy; it covers proof of address only.
