Why your certificate matters
From signed work
to recruiter-trusted proof.
Most online certificates are pretty PDFs nobody can verify. Ewance credentials are identity-checked, signed, anchored on-chain — and ready to drop into LinkedIn, your portfolio, or a recruiter's inbox in one tap.
Recruiters confirm authenticity in one click — no Ewance account or login required. The verification widget calls our public API and returns a signed authenticity statement in under a second.
Every credential is hashed and anchored on the LearnCoin chain at issue time. The hash is independent of Ewance—if our domain disappears tomorrow, the proof is still on a public ledger that anyone can verify.
