Out-of-scope for YONA

Regulated customer data (e.g., PII, Travel Rule payloads, destination coordinates)

Works alongside existing Travel Rule, compliance, custody, and settlement systems. Open to implement under CC BY 4.0. No YONA runtime network.

More

YONA does not replace Travel Rule, compliance, or settlement systems. It fits before those steps, enabling a clear authorization decision before later processes begin.

One Reference, No Manual Beneficiary Details for end-users

In YONA, users start from their own VASP’s app or service using one YONA-defined reference: a beneficiary_handle for push payments or an intent_locator for pull payments.

The reference gives the originator VASP enough information to continue without asking the user for blockchain addresses, tags, memos, wallet details, or separate beneficiary information. Any additional details are handled directly between VASPs, instead of being collected from the user through extra payment prompts.

Where to start

For decision-makers

Start with Pilot Overview to understand the current lower-lift pilot path, what stays unchanged, and what the pilot does and does not prove.

For engineers

Start with YONA Ruleset 1.0 for normative requirements, and Reference Messages & DID Examples.
