Credential Smart Contracts

Credential.sol and Credential1155.sol are smart contracts designed to allow users to register credentials. The contracts use OpenZeppelin open source contracts, such as AccessControl, ECDSA, and EIP712.

Main Features

The main features of these contracts are:

• The Issuer address specified in the constructor is a privileged signing address.
• Once a credential is registered, the subject address is minted an ERC721 or ERC1155 token.
• Users can check if a subject has a registered credential by calling checkRegistration().
• Credential.sol and Credential1155.sol use Access Control and ECDSA signature checking to ensure that a credential is signed by the specified issuer.

Credential.sol and Credential1155.sol use Access Control and ECDSA signature checking to ensure that a credential is signed by the issuer that was specified in the constructor
