Breaking changes

  • Update minimum pragma to 0.8.24 in SignatureChecker, Governor and Governor's extensions. (#5716).

Pragma changes

  • Reduced pragma requirement of interface files

Changes by category

Account

  • Account: Added a simple ERC-4337 account implementation with minimal logic to process user operations. (#5657)
  • AccountERC7579: Extension of Account that implements support for ERC-7579 modules of type executor, validator, and fallback handler. (#5657)
  • AccountERC7579Hooked: Extension of AccountERC7579 that implements support for ERC-7579 hook modules. (#5657)
  • EIP7702Utils: Add a library for checking if an address has an EIP-7702 delegation in place. (#5587)
  • IERC7821, ERC7821: Interface and logic for minimal batch execution. No support for additional opData is included. (#5657)

Governance

  • GovernorNoncesKeyed: Extension of Governor that adds support for keyed nonces when voting by sig. (#5574)

Tokens

  • ERC20Bridgeable: Implementation of ERC-7802 that makes an ERC-20 compatible with crosschain bridges. (#5739)

Cryptography

Signers
  • AbstractSigner, SignerECDSA, SignerP256, and SignerRSA: Add an abstract contract and various implementations for contracts that deal with signature verification. (#5657)
  • SignerERC7702: Implementation of AbstractSigner for Externally Owned Accounts (EOAs). Useful with ERC-7702. (#5657)
  • SignerERC7913: Abstract signer that verifies signatures using the ERC-7913 workflow. (#5659)
  • MultiSignerERC7913: Implementation of AbstractSigner that supports multiple ERC-7913 signers with a threshold-based signature verification system. (#5659)
  • MultiSignerERC7913Weighted: Extension of MultiSignerERC7913 that supports assigning different weights to each signer, enabling more flexible governance schemes. (#5741)
Verifiers
  • ERC7913P256Verifier and ERC7913RSAVerifier: Ready to use ERC-7913 verifiers that implement key verification for P256 (secp256r1) and RSA keys. (#5659)
Other
  • SignatureChecker: Add support for ERC-7913 signatures alongside existing ECDSA and ERC-1271 signature verification. (#5659)
  • ERC7739: An abstract contract to validate signatures following the rehashing scheme from ERC7739Utils. (#5664)
  • ERC7739Utils: Add a library that implements a defensive rehashing mechanism to prevent replayability of smart contract signatures based on the ERC-7739. (#5664)

Structures

  • EnumerableMap: Add support for BytesToBytesMap type. (#5658)
  • EnumerableMap: Add keys(uint256,uint256) that returns a subset (slice) of the keys in the map. (#5713)
  • EnumerableSet: Add support for StringSet and BytesSet types. (#5658)
  • EnumerableSet: Add values(uint256,uint256) that returns a subset (slice) of the values in the set. (#5713)

Utils

  • Arrays: Add unsafeAccess, unsafeMemoryAccess and unsafeSetLength for bytes[] and string[]. (#5568)
  • Blockhash: Add a library that provides access to historical block hashes using EIP-2935's history storage, extending the standard 256-block limit to 8191 blocks. (#5642)
  • Bytes: Fix lastIndexOf(bytes,byte,uint256) with empty buffers and finite position to correctly return type(uint256).max instead of accessing uninitialized memory sections. (#5797)
