Release Notes

nomicfoundation/hardhat (@​nomicfoundation/hardhat-chai-matchers)

v2.0.8

v2.0.6

Compare Source

This release improves the error messages of the .withArgs matcher (thanks @​RenanSouza2!)

v2.0.5

Compare Source

This version:

• Adds support for Typed objects (thanks @​RenanSouza2!)
• Improves how .revertedWithCustomError handles wrong number of arguments (thanks @​RenanSouza2!)

v2.0.4

Compare Source

This release improves the loading performance of the plugin

v2.0.3

Compare Source

This release adds support for Addressable objects in .withArgs and .equals (thanks @​Amxx!)

v2.0.2

Compare Source

This release forbids our async matchers from being chained. This means that you can't do something like:

await expect(contract.f())
  .to.changeEtherBalance(...)
  .and.to.changeTokenBalance(...)

This never worked properly, leading to potential false positives in tests. Now this pattern will throw an error to make it clear that it's not supported.

If some of your tests start throwing because of this, the way to do the same thing without chaining is:

const tx = contract.f();

await expect(tx).to.changeEtherBalance(...);
await expect(tx).to.changeTokenBalance(...);

v2.0.1

Compare Source

This version removes a dependency from the package that was no longer necessary.

v2.0.0

Compare Source

This new major version of Hardhat Chai Matchers works with the new version of our hardhat-ethers plugin. If you are going to use ethers v6, this is the version that you have to install. If you are still using ethers v5, then you should keep using version 1.x of this plugin.

As part of that, we dropped support for ethers v5's BigNumbers in this version. No other breaking changes were introduced to the API.

These removals were implemented in the following PRs: #​3637, #​3880, #​3945, #​4258, #​4276, #​4289

Changes by category

General

• Replaced revert strings and require statements with custom errors. (#​4261)
• Bumped minimum compiler version required to 0.8.20 (#​4288, #​4489)
• Use of abi.encodeCall in place of abi.encodeWithSelector and abi.encodeWithSignature for improved type-checking of parameters (#​4293)
• Replaced some uses of abi.encodePacked with clearer alternatives (e.g. bytes.concat, string.concat). (#​4504) (#​4296)
• Overrides are now used internally for a number of functions that were previously hardcoded to their default implementation in certain locations: ERC1155Supply.totalSupply, ERC721.ownerOf, ERC721.balanceOf and ERC721.totalSupply in ERC721Enumerable, ERC20.totalSupply in ERC20FlashMint, and ERC1967._getImplementation in ERC1967Proxy. (#​4299)
• Removed the override specifier from functions that only override a single interface function. (#​4315)
• Switched to using explicit Solidity import statements. Some previously available symbols may now have to be separately imported. (#​4399)
• Governor, Initializable, and UUPSUpgradeable: Use internal functions in modifiers to optimize bytecode size. (#​4472)
• Upgradeable contracts now use namespaced storage (EIP-7201). (#​4534)
• Upgradeable contracts no longer transpile interfaces and libraries. (#​4628)

Access

• Ownable: Added an initialOwner parameter to the constructor, making the ownership initialization explicit. (#​4267)
• Ownable: Prevent using address(0) as the initial owner. (#​4531)
• AccessControl: Added a boolean return value to the internal _grantRole and _revokeRole functions indicating whether the role was granted or revoked. (#​4241)
• access: Moved AccessControl extensions to a dedicated directory. (#​4359)
• AccessManager: Added a new contract for managing access control of complex systems in a consolidated location. (#​4121)
• AccessManager, AccessManaged, GovernorTimelockAccess: Ensure that calldata shorter than 4 bytes is not padded to 4 bytes. (#​4624)
• AccessManager: Use named return parameters in functions that return multiple values. (#​4624)
• AccessManager: Make schedule and execute more conservative when delay is 0. (#​4644)

Finance

• VestingWallet: Fixed revert during 1 second time window when duration is 0. (#​4502)
• VestingWallet: Use Ownable instead of an immutable beneficiary. (#​4508)

Governance

• Governor: Optimized use of storage for proposal data (#​4268)
• Governor: Added validation in ERC1155 and ERC721 receiver hooks to ensure Governor is the executor. (#​4314)
• Governor: Refactored internals to implement common queuing logic in the core module of the Governor. Added queue and _queueOperations functions that act at different levels. Modules that implement queuing via timelocks are expected to override _queueOperations to implement the timelock-specific logic. Added _executeOperations as the equivalent for execution. (#​4360)
• Governor: Added voter and nonce parameters in signed ballots, to avoid forging signatures for random addresses, prevent signature replay, and allow invalidating signatures. Add voter as a new parameter in the castVoteBySig and castVoteWithReasonAndParamsBySig functions. (#​4378)
• Governor: Added support for casting votes with ERC-1271 signatures by using a bytes memory signature instead of r, s and v arguments in the castVoteBySig and castVoteWithReasonAndParamsBySig functions. (#​4418)
• Governor: Added a mechanism to restrict the address of the proposer using a suffix in the description.
• GovernorStorage: Added a new governor extension that stores the proposal details in storage, with an interface that operates on proposalId, as well as proposal enumerability. This replaces the old GovernorCompatibilityBravo module. (#​4360)
• GovernorTimelockAccess: Added a module to connect a governor with an instance of AccessManager, allowing the governor to make calls that are delay-restricted by the manager using the normal queue workflow. (#​4523)
• GovernorTimelockControl: Clean up timelock id on execution for gas refund. (#​4118)
• GovernorTimelockControl: Added the Governor instance address as part of the TimelockController operation salt to avoid operation id collisions between governors using the same TimelockController. (#​4432)
• TimelockController: Changed the role architecture to use DEFAULT_ADMIN_ROLE as the admin for all roles, instead of the bespoke TIMELOCK_ADMIN_ROLE that was used previously. This aligns with the general recommendation for AccessControl and makes the addition of new roles easier. Accordingly, the admin parameter and timelock will now be granted DEFAULT_ADMIN_ROLE instead of TIMELOCK_ADMIN_ROLE. (#​3799)
• TimelockController: Added a state getter that returns an OperationState enum. (#​4358)
• Votes: Use Trace208 for checkpoints. This enables EIP-6372 clock support for keys but reduces the max supported voting power to uint208. (#​4539)

Metatx

• ERC2771Forwarder: Added deadline for expiring transactions, batching, and more secure handling of msg.value. (#​4346)
• ERC2771Context: Return the forwarder address whenever the msg.data of a call originating from a trusted forwarder is not long enough to contain the request signer address (i.e. msg.data.length is less than 20 bytes), as specified by ERC-2771. (#​4481)
• ERC2771Context: Prevent revert in _msgData() when a call originating from a trusted forwarder is not long enough to contain the request signer address (i.e. msg.data.length is less than 20 bytes). Return the full calldata in that case. (#​4484)

Proxy

• ProxyAdmin: Removed getProxyAdmin and getProxyImplementation getters. (#​3820)
• TransparentUpgradeableProxy: Removed admin and implementation getters, which were only callable by the proxy owner and thus not very useful. (#​3820)
• ERC1967Utils: Refactored the ERC1967Upgrade abstract contract as a library. (#​4325)
• TransparentUpgradeableProxy: Admin is now stored in an immutable variable (set during construction) to avoid unnecessary storage reads on every proxy call. This removed the ability to ever change the admin. Transfer of the upgrade capability is exclusively handled through the ownership of the ProxyAdmin. (#​4354)
• Moved the logic to validate ERC-1822 during an upgrade from ERC1967Utils to UUPSUpgradeable. (#​4356)
• UUPSUpgradeable, TransparentUpgradeableProxy and ProxyAdmin: Removed upgradeTo and upgrade functions, and made upgradeToAndCall and upgradeAndCall ignore the data argument if it is empty. It is no longer possible to invoke the receive function (or send value with empty data) along with an upgrade. (#​4382)
• BeaconProxy: Reject value in initialization unless a payable function is explicitly invoked. (#​4382)
• Proxy: Removed redundant receive function. (#​4434)
• BeaconProxy: Use an immutable variable to store the address of the beacon. It is no longer possible for a BeaconProxy to upgrade by changing to another beacon. (#​4435)
• Initializable: Use the namespaced storage pattern to avoid putting critical variables in slot 0. Allow reinitializer versions greater than 256. (#​4460)
• Initializable: Use intermediate variables to improve readability. (#​4576)

Token

• ERC20, ERC721, ERC1155: Deleted _beforeTokenTransfer and _afterTokenTransfer hooks, added a new internal _update function for customizations, and refactored all extensions using those hooks to use _update instead. (#​3838, #​3876, #​4377)
• ERC20: Removed Approval event previously emitted in transferFrom to indicate that part of the allowance was consumed. With this change, allowances are no longer reconstructible from events. See the code for guidelines on how to re-enable this event if needed. (#​4370)
• ERC20: Removed the non-standard increaseAllowance and decreaseAllowance functions. (#​4585)
• ERC20Votes: Changed internal vote accounting to reusable Votes module previously used by ERC721Votes. Removed implicit ERC20Permit inheritance. Note that the DOMAIN_SEPARATOR getter was previously guaranteed to be available for ERC20Votes contracts, but is no longer available unless ERC20Permit is explicitly used; ERC-5267 support is included in ERC20Votes with EIP712 and is recommended as an alternative. (#​3816)
• SafeERC20: Refactored safeDecreaseAllowance and safeIncreaseAllowance to support USDT-like tokens. (#​4260)
• SafeERC20: Removed safePermit in favor of documentation-only permit recommendations. Based on recommendations from @​trust1995 (#​4582)
• ERC721: _approve no longer allows approving the owner of the tokenId. (#​4377) _setApprovalForAll no longer allows setting address(0) as an operator. (#​4377)
• ERC721: Renamed _requireMinted to _requireOwned and added a return value with the current owner. Implemented ownerOf in terms of _requireOwned. (#​4566)
• ERC721Consecutive: Added a _firstConsecutiveId internal function that can be overridden to change the id of the first token minted through _mintConsecutive. (#​4097)
• ERC721URIStorage: Allow setting the token URI prior to minting. (#​4559)
• ERC721URIStorage, ERC721Royalty: Stop resetting token-specific URI and royalties when burning. (#​4561)
• ERC1155: Optimized array allocation. (#​4196)
• ERC1155: Removed check for address zero in balanceOf. (#​4263)
• ERC1155: Optimized array accesses by skipping bounds checking when unnecessary. (#​4300)
• ERC1155: Bubble errors triggered in the onERC1155Received and onERC1155BatchReceived hooks. (#​4314)
• ERC1155Supply: Added a totalSupply() function that returns the total amount of token circulating, this change will restrict the total tokens minted across all ids to 2**256-1 . (#​3962)
• ERC1155Receiver: Removed in favor of ERC1155Holder. (#​4450)

Utils

• Address: Removed the ability to customize error messages. A common custom error is always used if the underlying revert reason cannot be bubbled up. (#​4502)
• Arrays: Added unsafeMemoryAccess helpers to read from a memory array without checking the length. (#​4300)
• Arrays: Optimized findUpperBound by removing redundant SLOAD. (#​4442)
• Checkpoints: Library moved from utils to utils/structs (#​4275)
• DoubleEndedQueue: Refactored internal structure to use uint128 instead of int128. This has no effect on the library interface. (#​4150)
• ECDSA: Use unchecked arithmetic for the tryRecover function that receives the r and vs short-signature fields separately. (#​4301)
• EIP712: Added internal getters for the name and version strings (#​4303)
• Math: Makes ceilDiv to revert on 0 division even if the numerator is 0 (#​4348)
• Math: Optimized stack operations in mulDiv. (#​4494)
• Math: Renamed members of Rounding enum, and added a new rounding mode for "away from zero". (#​4455)
• MerkleProof: Use custom error to report invalid multiproof instead of reverting with overflow panic. (#​4564)
