Minor Changes
#8442
4904c72Thanks @ChristopherDedominici! - Support test name filter negation (--grep-exclude) for Solidity and Mocha tests.#8472
2a66c2eThanks @kanej! - Added experimental EIP-7843 support to the Amsterdam hardfork: blocks now include theslotNumberheader field, and theSLOTNUM(0x4b) opcode returns it. EDR has no consensus layer, so the value is simulated: it increments by one per mined block, starting at 0 on a new chain, or from the forked block's slot number when forking.Patch Changes

eb4826aThanks @ChristopherDedominici! - Fix a bug where the EIP-712 collector throws for a struct of the same name in a source file the user didn't include.#8443
b5674eaThanks @Kropiunig! - Fixed the HD wallet derivation-path validator so malformed paths containing stray colons (e.g.m:/44'/60'/0'/0) are rejected with theINVALID_HD_PATHerror.#8411
5eb4f0eThanks @BROCCOLO1D! - Support Solidity testmemoryLimitand fuzz/invarianttimeoutconfig options.Updated dependencies:

81871fdThanks @tenderdeve! - Explain the unsupported cheatcodeeip712HashType(string,string)and point to the documentation for the alternative instead.#8400
2f48724Thanks @kanej! - Support setting the transaction gas cap in Solidity Tests#8367
82d00fcThanks @alcuadrado! - Lazy load dependencies to optimize bootstrap time#8391
f3c5727Thanks @schaable! - Makehardhat test solidity --snapshot-checkread-only. It no longer rewrites or deletes.gas-snapshotorsnapshots/*.jsonfiles, and instead reports differences. The command now fails when a stored gas value differs from the current one, or when no baseline exists, with a hint to run--snapshot.#8332
e542a48Thanks @gultekinmakif! - Fixed a crash that could occur when a network returned an unexpected response while resolving the default sender account#8385
946e379Thanks @BROCCOLO1D! - When a Hardhat 2 plugin calls an API that no longer exists in Hardhat 3, the error now names the specific API that was used and explains how to migrate it to Hardhat 3.Updated dependencies:
v3.9.0Compare Source
Minor Changes
0fd498dThanks @kanej! - Added support forcoverage.skipFiles, a list of globs of Solidity files to exclude from coverage instrumentation and reporting during a--coveragerun.Patch Changes
#8383
1660f1eThanks @schaable! - Fixed an intermittent "Provider for provided chain type does not exist" error that could occur when multiple network connections were created concurrently.#8371
287620eThanks @gultekinmakif! - Account overrides that share an address with the network's built-in genesis accounts are now correctly merged into a single genesis entry.#8375
931a5f0Thanks @schaable! - Suppressed the solc initcode size warning for Solidity test contracts and when running under--coverage.#8372
5f6aff2Thanks @gultekinmakif! - Improved validation forinitialDatenetwork configuration. InvalidDateobjects and unparseable datestrings are now rejected during config loading rather than causing a runtime error later.v3.8.0Compare Source
Minor Changes
#8339
f21390fThanks @alcuadrado! - AddeddefinePlugin, a new helper exported fromhardhat/plugins. Plugin authors should wrap their plugin literal with it so the default export of theirindexmodule becomes:definePluginreturns its argument unchanged and, as a side effect, registers the plugin's id in a process-wide registry of loaded plugins. Hardhat's CLI uses that registry to warn when a plugin is imported but missing from the user'spluginsarray.#8339
19c6927Thanks @alcuadrado! - Hardhat now warns when a plugin is imported in your Hardhat config file but missing from thepluginsarray. The warning is printed to stderr after the runtime environment is created, listing the offending plugins and pointing the user at the fix.If your Hardhat config file is written in TypeScript, for the warning to be reliable your project's
tsconfig.jsonmust enableverbatimModuleSyntax: true. Without it, TypeScript deletes unused default-value imports, so an unused plugin can't be detected.Patch Changes
#8336
86bfe66Thanks @Wodann! - - Fixed default gas limit of Solidity test runner when a custom transaction gas cap (EIP-7825) or block gas limit is specified#8345
9d5b96cThanks @alcuadrado! - Add.solidityStackproperty to theSolidityErrorexceptions generated by EDR#8365
dbb689bThanks @kanej! - Suppress the solc contract size warning for Solidity test files.#8368
2e2ba99Thanks @kanej! - Fixed thebuildtask attempting to download a compiler even though apathto a local compiler is configured.#8339
25cea9fThanks @alcuadrado! - The sample projects initialized withhardhat --initnow setverbatimModuleSyntax: truein theirtsconfig.json. This ensures that plugin imports inhardhat.config.tsare actually evaluated at runtime, which is required for the new "imported but unused plugin" warning to work reliably.Updated dependencies:

Minor Changes
#8327
dee44f6Thanks @alcuadrado! - Add acleanupArtifactsoption toSolidityBuildSystem#build. Whentrue, the build system runscleanupArtifactsagainst the build's root file paths after a successful build, deleting orphan artifacts and unreachable build-info files for the scope.#8327
dee44f6Thanks @alcuadrado! - Deprecate the followingSolidityHooks:getCompiler,onCleanUpArtifacts,preprocessProjectFileBeforeBuilding,preprocessSolcInputBeforeBuilding,readSourceFile,invokeSolc, andreadNpmPackageRemappings. They will be removed in a future release.Use
processArtifactsAfterSuccessfulBuildinstead ofonCleanUpArtifacts, andgetCompilationJobErrorsinstead ofinvokeSolc.#8327
dee44f6Thanks @alcuadrado! - AddSolidityHooks#getCompilationJobErrorshook, which lets plugins process the compiler output errors of a compilation job before they are reported to the user.#8327
dee44f6Thanks @alcuadrado! - AddSolidityHooks#processArtifactsAfterSuccessfulBuildhook to let plugins post-process the artifacts. The hook receives the resolved build options as a new exportedResolvedBuildOptionstype.Patch Changes

793cc84Thanks @kanej! - Disable transaction gas cap and block gas limit when running tests under--coverage.#8270
cf2823bThanks @schaable! - Solidity test configuration now also accepts{ profiles: { default: ... } }. Only thedefaultprofile is currently supported, other profile names will be supported in a future release. The previous flat shape continues to work unchanged.The resolved
HardhatConfig.test.solidityis now profile-keyed: read per-profile fields athre.config.test.solidity.profiles.default.*instead ofhre.config.test.solidity.*. Plugins that read the resolved Solidity test config need to be updated.Patch Changes

8452f97Thanks @alcuadrado! - Export./package.jsonso consumers can import the package's manifest.#8310
9f394ecThanks @js360000! - Fix JSON-RPCerror.datashape for revert errors (code 3): return the raw revert hex string directly instead of a{ message, txHash, data }wrapper object. This matches the geth/anvil/EVM-node convention that client tooling (viem, ethers, web3.js) relies on when decoding custom errors. Closes #8075.#8269
