What should I look for in a decentralized identity platform?

Support for the core standards (W3C VC, DIDs, OpenID4VC), the credential formats your ecosystem uses, a clear wallet strategy, revocation and trust-registry features, and interoperability evidence such as conformance to the HAIP profile or eIDAS ARF.

Which decentralized identity vendors should I evaluate?

The field includes Microsoft Entra Verified ID, MATTR, SpruceID, Dock, Trinsic, walt.id, Affinidi, Indicio, Gataca, and others. Shortlist by your use case (issuer vs verifier, government interop vs private ecosystem) rather than brand.

How to Choose a Decentralized Identity Platform

Q: Should I buy a platform or build on open standards myself?

Buy when you need issuance and verification in production quickly, want managed wallets and revocation, or must interoperate with government wallets. Build on open libraries when your needs are narrow and you have the cryptographic engineering depth to own it.

Decentralized identity platforms vary widely, from developer toolkits to managed issuance-and-verification clouds to government-grade wallet infrastructure. This buyer guide helps you evaluate them without getting lost in marketing. If you are still deciding whether you need one, start with decentralized identity explained.

Start from your use case

The single biggest filter is what you are trying to do:

Verifier only: you want to accept credentials others issue. Prioritize verification SDKs, wallet compatibility, and OpenID4VP support.
Issuer: you want to issue portable credentials. Prioritize signing, schema management, revocation, and OpenID4VCI.
Government or regulated interop: you must work with the EUDI Wallet or mDL. Prioritize ARF and HAIP conformance above all.

The capabilities that matter

Evaluate every shortlisted vendor against these:

Standards support: genuine W3C Verifiable Credentials, DIDs, and OpenID4VC, not a proprietary credential format wrapped in the vocabulary.
Credential formats: does it support the format your ecosystem uses (SD-JWT VC, W3C Data Integrity, AnonCreds)?
Wallet strategy: does it provide a wallet, integrate third-party wallets, or both? Who owns the holder relationship?
Revocation and status: how are credentials revoked and checked?
Trust framework: does it support trust registries and governance, or leave that to you?
Privacy: selective disclosure at minimum; BBS signatures or ZKPs if unlinkability matters.
Interoperability evidence: conformance test results, HAIP alignment, participation in EU large-scale pilots.

Questions that separate substance from marketing

"Which credential formats and DID methods do you support in production, not on a roadmap?"
"Show me an interop test result against another vendor's wallet or verifier."
"How does revocation work, and what does a verifier do offline?"
"If we leave, what happens to issued credentials and the holder wallets?"
"Are you aligned to the eIDAS ARF and OpenID4VC HAIP?"

Buy vs build

Buy a platform when you need production issuance or verification quickly, want managed wallets and revocation, or must interoperate with government wallets. Build on open libraries (many vendors, such as walt.id and SpruceID, offer them) when your scope is narrow and you have the cryptographic engineering depth to own key management and upgrades.

The vendor landscape

The decentralized identity vendor directory profiles the active platforms, and best decentralized identity platforms and best decentralized identity for enterprises rank them. Shortlist three to five by use case, then run the questions above against each.
