Crypto Travel Rule Messaging Protocols

The FATF’s Recommendation 16 on Wire Transfers, “Travel Rule,” requires virtual asset service providers (VASPs), financial institutions, and obliged entities to exchange originator and beneficiary identifying information with counterparties during crypto transfers above $1,000.* 

*Note that different jurisdictions have different transaction threshold amounts.

Before this recommendation, and due to the public nature of blockchain transactions, no messaging protocols to send and receive customer personally identifiable information (PII) existed. Various companies and industry working groups created several Travel Rule messaging protocols to address a large component of travel rule compliance: safely and securely transferring customer PII alongside blockchain transactions.

This article will assess:

What is a Travel Rule Messaging Protocol?

A Travel Rule messaging protocol allows VASPs to securely exchange Originator and Beneficiary Customer information securely.

As a comparison, the two most widely used internet standard communication protocols for email transmission are SMTP (Simple Mail Transfer Protocol) and Internet Message Access Protocol (IMAP). Mail servers and other message transfer agents use SMTP and IMAP to send and receive mail messages. To comply with FATF’s Travel Rule Recommendation, VASPs need a similar messaging protocol to exchange originator and beneficiary information.

Why are there multiple Travel Rule messaging protocols? 

Once FATF recommended the Travel Rule, various working groups and private companies took on the task of building viable initiatives to solve the technical aspect of the Travel Rule.

While it is great that there are multiple protocols that are coming live, VASPs often are not sure which to support. We believe that with time protocols may merge or some may stop being in use. Until then, we choose to take an agnostic approach and support all major protocols, so that our customers are not faced with the difficult decision of picking one protocol over another. 

For example, there were many electronic mailing messaging protocols before SMTP and IMAP became the standard. During that time, if you wanted to send an email to someone in another system, you needed a gateway. Years later, SMTP and IMAP became the standard due to their simplicity.  

What should a complete Crypto Travel Rule solution entail?

A complete FATF’s Crypto Travel Rule solution allows crypto businesses and financial institutions to:

  1. Determine counterparty type of a transaction,
  2. Apply appropriate jurisdictional requirements,
  3. Sanctions-screen on each counterparty,
  4. Rely on blockchain analytics providers as a source to identify counterparty VASPs and assess risk score of an address
  5. Perform VASP due diligence before allowing transactions with them
  6. Store customer and beneficiary personally identifiable information (PII) in a GDPR-compliant manner and for record-keeping / reporting purposes, and
  7. Send and receive customer PII to and from VASPs using a wide variety of blockchain messaging protocols.

A Travel Rule messaging protocol addresses only one of the seven components to full compliance. Messaging protocols still need to be integrated into a complete Travel Rule solution.

Which FATF R.16 Crypto Travel Rule messaging protocols are currently on the market?

Since FATF launched its requirements, the crypto industry has already started several initiatives to solve the technical aspect of the travel rule. These consist of protocols built by industry alliance networks, closed groups of exchanges, and private companies as commercial offerings. While addressing the same challenge, the messaging protocols differ in terms of implementation requirements, how they solve discovery, governance models and costs of becoming members.

*Please note that TRNow is not a Travel Rule messaging protocol, rather a multi-protocol switch that enables the secure exchange of Travel Rule data with any counterparty VASP.
