MonSeal

I built a universal verification platform on Monad (Testnet) issue tamper-proof credentials, verify them instantly with a QR code. Problem: Millions of documents people rely on every day like degrees, experience letters, warranty cards, event tickets, ownership records etc, can be forged, altered, or lost. Verifying them today means emails, phone calls, and manual checks between the verifier and the issuing organization, with no fast or universal way to confirm authenticity. Solution: MonSeal lets approved organizations issue credentials whose cryptographic hash, issuer, and timestamp are sealed on Monad. Anyone , no account, no wallet, no login can scan a QR code or paste a credential ID and get an instant public answer: verified, revoked, expired, or tampered. Issuing is gated by an on-chain approval system (organizations apply, get reviewed, and only approved wallets can successfully issue), so the trust guarantee comes from the smart contract itself, not from a database anyone could edit.
