For issuers

Your brand. Our plumbing.

Schools, employers, training platforms: any organization that issues credentials can use LearnCoin as its cryptographic backbone. Your brand stays in front of the recipient, your domain owns the relationship, your certificate design. LearnCoin is invisible infrastructure underneath.

First issuer

Ewance — real-world challenges, on-chain credentials

Ewance is a higher-education platform that runs industry-sponsored real-world challenges. When a student completes a challenge, Ewance issues a credential through LearnCoin with the student's skills mapped to and custom competency frameworks.

Integration took about a week from API key provisioning to first live credential. Ewance passes tenant metadata through the REST API; LearnCoin writes the OB 3.0 entries into the signed credential and the verification page renders the Ewance brand above the fold.

Every Ewance credential today is a W3C VC 2.0 + Blockcerts v3 + Open Badges 3.0 credential anchored on Base Sepolia ( testnet).
