## VERIFIABLE CREDENTIALS

# Issue and verify credentials at scale

Harness the power of W3C Verifiable Credentials onchain for any use case, accessible everywhere you need them.

Effective digital credentials

## What are Verifiable Credentials?

Credentials help individuals and businesses prove claims daily, from driver licenses to income verification.

However, digitizing credentials has been challenging due to a lack of universal standards, leading to fragmentation.

Crossmint’s Verifiable Credential solution enables onchain credentials that are standard-compliant, cryptographically secure, interoperable, and machine-verifiable.

For any credential use case

## Seamless Credential Interoperability

Crossmint’s onchain credentials are interoperable out of the box, working with all wallet providers. As such, users can effortlessly and securely bring their credentials with them to any application. This built-in interoperability supercharges the practical benefits and adoption of credentials online.
