Summary
This proposal submits Vera, a bounded trust-anchor and verifiable-credential integration layer for Canton. It delivers a reusable pattern for DID recording, credential issuance, off-chain presentation verification, and Canton-side consumption of verification outcomes, so Canton applications can enforce participation and transfer eligibility rules without rebuilding identity and trust glue from scratch.
The first release is intentionally narrow and practical. It focuses on a minimal did:canton method, one standards-aligned resolver and registrar integration path, a Canton VC application for credential issuance, and two proving flows: credential-backed transfer authorization and credential-backed offer or participation eligibility.

Notes for Reviewers
This proposal is deliberately scoped as a reusable trust-integration layer, not a full decentralized identity platform. It does not attempt to deliver wallet infrastructure, universal DID method support, issuer products, or native on-ledger VC verification in the first release.
The main proving case is credential-backed transfer authorization, because it is the clearest ecosystem-facing flow for current Canton usage. A second proving flow shows that the same trust layer also supports broader institution-facing participation and approval workflows.
The attached diagrams are meant to make the execution model easier to evaluate:
- DID recording and credential issuance through the Canton VC application
- Credential-backed transfer authorization
- Credential-backed offer or participation eligibility
