sdcreceipt-ts
Verify VSL Settlement Receipts, sign settlement triggers and request Receipts from an issuer in TypeScript, with the same results as sdcreceipt, the reference implementation.
Conforms to:
- the VSL conformance kit 1.1: all 17 Receipt vectors, each invalid one failing on the check the manifest names, and all 5 key-document cases;
- sdcgovernance's vectors: all 21 RFC 8785 vectors, and the decision-table and governance-Receipt vectors (every table hash, all 37 evaluations, all 9 governance Receipts).
CI runs both, pinned to a fixed commit and release.
It runs in Node (20 or later), Deno and browsers. Verifying and signing need no network and no
account. You supply the keys, so a Receipt can never nominate the key it is judged by. Only settle
reaches an issuer.
