EMOZ’s smart contract is a non-transferable ERC-721 (soulbound NFT) contract on the Polygon blockchain:
Issues immutable certificates as NFTs.
Stores public data: SHA-256 file hash and algorithm.
Stores encrypted metadata: Declaring user’s name, declaration, email hash.
Can only be used by EMOZ to issue certificates.
Fully transparent: Public code on Polygonscan
The contract ensures permanence, immutability, and auditability: even if EMOZ were to shut down.
