Solidus Identity
Solidus Identity vs Credo TS
Credo TS is excellent, EUDI-embedded infrastructure — and it's a library. Every project built on it still stands up its own network, issuer, and trust registry. Solidus ships all three already running.
Solidus is a public testnet: no mainnet, no token, no external audit, and no paying customer. Every claim below is checkable; none of them are a substitute for the certifications an incumbent already holds.
What Credo TS does better
- Embedded in the FUNKE-winning EasyPID prototype, Germany's EUDI wallet reference build — Solidus has no equivalent implementation pedigree.
- Stewarded by the OpenWallet Foundation since 2024 — broader institutional backing than Solidus's DIF Associate-level standing.
- Broader standards coverage shipped today: DIDComm v1/v2, OID4VC, AnonCreds, SD-JWT VC, and BBS+ across Node.js and React Native.
- An actively maintained, multi-year track record (0.5/0.6 releases through 2025) as the de-facto default SDK for EUDI wallet implementations.
Where Solidus is different
- Credo has no network, no L1, no chain-anchored issuance, and no revenue model of its own, per its own brief — Solidus ships network, SDK, and issuer together.
- did:solidus is registered in the W3C DID Method Registry and resolves on a live testnet RPC, which a network-agnostic framework doesn't provide by itself.
- Native KYC issuance via Verify in the same stack — a framework alone doesn't issue credentials; you still have to build or buy that layer.

| Institutional stewardship | DIF Associate Member | OpenWallet Foundation-stewardedCredo TS wins |
| Standards coverage shipped | DID, VC, SD-JWT VC, BBS+ (testnet, unaudited) | DIDComm v1/v2, OID4VC, AnonCreds, SD-JWT VC, BBS+Credo TS wins |
| Production maturity | Public testnet, unaudited, no paying customer | Active multi-year releases, embedded in a real EUDI pilotCredo TS wins |
| What it is | Network + SDK + native KYC issuer, one stack | TypeScript framework only (DIDComm/VC); no network of its own |
| Chain-anchored trust | did:solidus resolves on a live testnet | None — network-agnostic framework, per brief |
| Native KYC / credential issuance | Native, via Verify | Not offered — framework only |
| Vertical completeness | One vendor: network, SDK, and issuer together | SDK only; network, issuer, and trust registry left to the implementer |
