Verifications

Onchain proof that a user is verified

Let users prove they've passed identity checks with a privacy-preserving attestation, without sharing personal data.

check.ts
const { verified, country } = await yb.verifications.check({ address: userAddress, schema: "account-verified" }) if (!verified) showVerifyPrompt()

What you get

Privacy first

No personal data is published onchain.

Reusable

Verify once, use across apps.

Enforce geographic rules.
