Verifiable Credentials is a W3C standard to make credentials in the digital world. It can be used to build digital IDs cards, academic diplomas, membership passes, and any kind of credential or proof of achievement you may want to attach to a subject.

Integrating Verifiable Credentials in your app can be tedious. You must implement issuance in a cryptographically correct way. Then figure out a way to store and distribute credentials to your users. Then have a revocation server. Finally, you need to provide instructions or SDKs to all parties who want to verify them. And re-do all of this if you want your credentials to work on-chain inside smart contracts.

Crossmint allows you to issue, store, distribute, present and verify VCs, all in under 5 lines of code, with an implementation that is 100% standards compliant and interoperable, and works both off and on-chain.

Verifiable Credentials is in public Beta. It can only be accessed through the Staging console.

Key Characteristics

How Does it Work?

Crossmint’s Verifiable Credentials SDK helps in all 4 components of the lifecycle of a credential:

  1. Issuance: define the schema for your credentials, and then issue credentials to users, identified by emails, phone numbers, crypto wallet addresses, or your custom user id. You can also revoke credentials.

  2. Storage: Crossmint can store all credentials for you in centralized storage, or can end to end encrypt and store them in a decentralized permanent storage network.

  3. Presentation: easily retrieve all the credentials of a user filtering only the ones you are interested in. Works with any wallet that supports the wallet connect interface.

  4. Verification: cryptographically validate that a credential you have been presented is valid. Use it to authorize users against your system.

Typically, issuance and storage are performed by one party, presentation and verification by another.
