@onchain-id/solidity - npm Package Versions

[2.2.1]

Changed

• Replaced the storage slot used for ImplementationAuthority on the proxies, to avoid conflict with ERC-1822 on block explorers. By using the same storage slot, the explorers were identifying this proxy as an ERC-1822, while it's a different implementation here, the storage slot is not used to store the address of the implementation but the address to ImplementationAuthority contract that references the implementation

[2.2.0]

Added

• Identities are now required to implement the standardized function isClaimValid(IIdentity _identity, uint256 claimTopic, bytes calldata sig, bytes calldata data) external view returns (bool), used for self-attested claims (_identity is the address of the Identity contract).
• Implemented the isClaimValid function in the Identity contract.
• IdFactory now implements the implementationAuthority() getter.

[2.1.0]

Added

• Implemented a new contract Gateway to interact with the IdFactory. The Gateway contract allows individual accounts (being EOA or contracts) to deploy identities for their own address as a salt. To deploy using a custom salt, a signature from an approved signer is required.
• Implemented a new base contract Verifier to be extended by contract requiring identity verification based on claims and trusted issuers.

[2.0.1]

Added

• added method createIdentityWithManagementKeys() that allows the factory to issue identities with multiple management keys.
• tests for the createIdentityWithManagementKeys() method

[2.0.0]

Added

• Add typechain-types (targeting ethers v5).
• Add tests cases for execute and approve methods.
• Add method revokeClaimBySignature(bytes signature) in ClaimIssuer, prefer using this method instead of the now deprecated revokeClaim method.
• Add checks on ClaimIssuer to prevent revoking an already revoked claim.
• Added Factory for ONCHAINIDs

Updated

• Switch development tooling to hardhat.
• Implemented tests for hardhat (using fixture for faster testing time).
• Prevent calling approve method with a non-request execute nonce (added a require on executionNone).
