hardhat

# hardhat ## 3.8.0 ### Minor Changes - [#8339](https://github.com/NomicFoundation/hardhat/pull/8339) [`f21390f`](https://github.com/NomicFoundation/hardhat/commit/f21390fe78773d8ba514cd4a64954220437293e3) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Added `definePlugin`, a new helper exported from `hardhat/plugins`. Plugin authors should wrap their plugin literal with it so the default export of their `index` module becomes: ```ts import type { HardhatPlugin } from "hardhat/types/plugins"; import { definePlugin } from "hardhat/plugins"; const hardhatPlugin: HardhatPlugin = definePlugin({ id: "my-plugin", // ... }); export default hardhatPlugin; ``` `definePlugin` returns 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's `plugins` array. - [#8339](https://github.com/NomicFoundation/hardhat/pull/8339) [`19c6927`](https://github.com/NomicFoundation/hardhat/commit/19c6927372fb39c4c4f0afe37895c738abbde237) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Hardhat now warns when a plugin is imported in your Hardhat config file but missing from the `plugins` array. 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.json` must enable `verbatimModuleSyntax: true`. Without it, TypeScript deletes unused default-value imports, so an unused plugin can't be detected. ### Patch Changes - [#8336](https://github.com/NomicFoundation/hardhat/pull/8336) [`86bfe66`](https://github.com/NomicFoundation/hardhat/commit/86bfe66b9b73c52649be2207b00b315a3b758f25) Thanks [@Wodann](https://github.com/Wodann)! - - Fixed default gas limit of Solidity test runner when a custom transaction gas cap (EIP-7825) or block gas limit is specified - Fixed process deadlock/hang when dropping a provider with interval mining and logging enabled - Print more detailed error descriptions for EVM, invariant fuzz, and cheatcode errors - [#8345](https://github.com/NomicFoundation/hardhat/pull/8345) [`9d5b96c`](https://github.com/NomicFoundation/hardhat/commit/9d5b96c59b4b84db549fff18144e6d0c8b129901) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Add `.solidityStack` property to the `SolidityError` exceptions generated by EDR - [#8365](https://github.com/NomicFoundation/hardhat/pull/8365) [`dbb689b`](https://github.com/NomicFoundation/hardhat/commit/dbb689b94925a949c554708d7ded2d9dde074270) Thanks [@kanej](https://github.com/kanej)! - Suppress the solc contract size warning for Solidity test files. - [#8368](https://github.com/NomicFoundation/hardhat/pull/8368) [`2e2ba99`](https://github.com/NomicFoundation/hardhat/commit/2e2ba996cc7c8a3056da3352defeb9cc9eba0cb2) Thanks [@kanej](https://github.com/kanej)! - Fixed the `build` task attempting to download a compiler even though a `path` to a local compiler is configured. - [#8339](https://github.com/NomicFoundation/hardhat/pull/8339) [`25cea9f`](https://github.com/NomicFoundation/hardhat/commit/25cea9f9789c56d3e43f1cc8f0f7a34adde89605) Thanks [@alcuadrado](https://github.com/alcuadrado)! - The sample projects initialized with `hardhat --init` now set `verbatimModuleSyntax: true` in their `tsconfig.json`. This ensures that plugin imports in `hardhat.config.ts` are actually evaluated at runtime, which is required for the new "imported but unused plugin" warning to work reliably. - Updated dependencies: - @nomicfoundation/hardhat-errors@3.0.15 ## 3.7.0 ### Minor Changes - [#8200](https://github.com/NomicFoundation/hardhat/pull/8200) [`ce430ac`](https://github.com/NomicFoundation/hardhat/commit/ce430ac97113e743ff6b2d34105f1ebde90d0d91) Thanks [@tenderdeve](https://github.com/tenderdeve)! - Hardhat 3 is now stable, the "Beta" wording is being dropped from the `hardhat --init` process and project templates. ## 3.6.0 ### Minor Changes - [#8327](https://github.com/NomicFoundation/hardhat/pull/8327) [`dee44f6`](https://github.com/NomicFoundation/hardhat/commit/dee44f69cafb9a11b702abe73e6215a954f16937) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Add a `cleanupArtifacts` option to `SolidityBuildSystem#build`. When `true`, the build system runs `cleanupArtifacts` against the build's root file paths after a successful build, deleting orphan artifacts and unreachable build-info files for the scope. - [#8327](https://github.com/NomicFoundation/hardhat/pull/8327) [`dee44f6`](https://github.com/NomicFoundation/hardhat/commit/dee44f69cafb9a11b702abe73e6215a954f16937) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Deprecate the following `SolidityHooks`: `getCompiler`, `onCleanUpArtifacts`, `preprocessProjectFileBeforeBuilding`, `preprocessSolcInputBeforeBuilding`, `readSourceFile`, `invokeSolc`, and `readNpmPackageRemappings`. They will be removed in a future release. Use `processArtifactsAfterSuccessfulBuild` instead of `onCleanUpArtifacts`, and `getCompilationJobErrors` instead of `invokeSolc`. - [#8327](https://github.com/NomicFoundation/hardhat/pull/8327) [`dee44f6`](https://github.com/NomicFoundation/hardhat/commit/dee44f69cafb9a11b702abe73e6215a954f16937) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Add `SolidityHooks#getCompilationJobErrors` hook, which lets plugins process the compiler output errors of a compilation job before they are reported to the user. - [#8327](https://github.com/NomicFoundation/hardhat/pull/8327) [`dee44f6`](https://github.com/NomicFoundation/hardhat/commit/dee44f69cafb9a11b702abe73e6215a954f16937) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Add `SolidityHooks#processArtifactsAfterSuccessfulBuild` hook to let plugins post-process the artifacts. The hook receives the resolved build options as a new exported `ResolvedBuildOptions` type. ### Patch Changes - [#8327](https://github.com/NomicFoundation/hardhat/pull/8327) [`dee44f6`](https://github.com/NomicFoundation/hardhat/commit/dee44f69cafb9a11b702abe73e6215a954f16937) Thanks [@alcuadrado](https://github.com/alcuadrado)! - `SolidityBuildSystem#cleanupArtifacts` now returns the list of artifact paths that remain after the cleanup. - [#8335](https://github.com/NomicFoundation/hardhat/pull/8335) [`a4bf547`](https://github.com/NomicFoundation/hardhat/commit/a4bf547bd7bc7d60e63fc31efc3dd27edb197b78) Thanks [@gultekinmakif](https://github.com/gultekinmakif)! - Allow STRING_WITHOUT_DEFAULT and FILE_WITHOUT_DEFAULT as positional arguments - [#8326](https://github.com/NomicFoundation/hardhat/pull/8326) [`959f2e1`](https://github.com/NomicFoundation/hardhat/commit/959f2e1989c4bcbff05f717b33a2df1098f67616) Thanks [@kanej](https://github.com/kanej)! - Fixed `hardhat flatten` silently producing a misleading output for projects with cyclic Solidity dependencies. - [#8262](https://github.com/NomicFoundation/hardhat/pull/8262) [`d3ba170`](https://github.com/NomicFoundation/hardhat/commit/d3ba17006874715de86194c6a136cd0b7afb9bc4) Thanks [@fvictorio](https://github.com/fvictorio)! - Add AGENTS.md and agentic skills to sample projects - Updated dependencies: - @nomicfoundation/hardhat-utils@4.1.3 - @nomicfoundation/hardhat-errors@3.0.14 ## 3.5.1 ### Patch Changes - [#8316](https://github.com/NomicFoundation/hardhat/pull/8316) [`971a135`](https://github.com/NomicFoundation/hardhat/commit/971a135becc86dea7a3039148b55d0774c7c26a0) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Fix `hardhat --init` when used with pnpm 11 - [#8302](https://github.com/NomicFoundation/hardhat/pull/8302) [`fb99caa`](https://github.com/NomicFoundation/hardhat/commit/fb99caa5b9bf75ffa70d2488112755b8de94e7a3) Thanks [@ChristopherDedominici](https://github.com/ChristopherDedominici)! - Suppress solc warnings that are direct side effects of `--coverage` instrumentation. - [#8315](https://github.com/NomicFoundation/hardhat/pull/8315) [`90650fd`](https://github.com/NomicFoundation/hardhat/commit/90650fd841a800adecdae011c196c8ec83a1a053) Thanks [@schaable](https://github.com/schaable)! - Improved error messages for common migration errors. ## 3.5.0 ### Minor Changes - [#8301](https://github.com/NomicFoundation/hardhat/pull/8301) [`793cc84`](https://github.com/NomicFoundation/hardhat/commit/793cc84d311ff96b1725f5b83a0063b9a28e3d19) Thanks [@kanej](https://github.com/kanej)! - Disable transaction gas cap and block gas limit when running tests under `--coverage`. - [#8270](https://github.com/NomicFoundation/hardhat/pull/8270) [`cf2823b`](https://github.com/NomicFoundation/hardhat/commit/cf2823b5ec9b5e6427c874636393a5ffcb70f412) Thanks [@schaable](https://github.com/schaable)! - Solidity test configuration now also accepts `{ profiles: { default: ... } }`. Only the `default` profile 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.solidity` is now profile-keyed: read per-profile fields at `hre.config.test.solidity.profiles.default.*` instead of `hre.config.test.solidity.*`. Plugins that read the resolved Solidity test config need to be updated. ### Patch Changes - [#8298](https://github.com/NomicFoundation/hardhat/pull/8298) [`83b1ae1`](https://github.com/NomicFoundation/hardhat/commit/83b1ae1bdc3b941f9e15f9d2d92cadf88f7a8747) Thanks [@Wodann](https://github.com/Wodann)! - - Fixed a bug when using a test filter where the `setUp` function would be run for empty test suites - Fixed a bug where snapshot cheatcodes would throw an error if names were invalid - Fixed coverage instrumentation interfering with the single-call `vm.prank` cheatcode - Added support for instrumentation of Solidity 0.8.35 - [#8264](https://github.com/NomicFoundation/hardhat/pull/8264) [`8452f97`](https://github.com/NomicFoundation/hardhat/commit/8452f9726205540e1684d3f8458bfd145e790226) Thanks [@alcuadrado](https://github.com/alcuadrado)! - Export `./package.json` so consumers can import the package's manifest. - [#8310](https://github.com/NomicFoundation/hardhat/pull/8310) [`9f394ec`](https://github.com/NomicFoundation/hardhat/commit/9f394ec7547cf7dd3392aeb826fca96b9c0aca28) Thanks [@js360000](https://github.com/js360000)! - Fix JSON-RPC `error.data` shape for revert errors (code 3): return the raw revert hex string directly instead of a `{ message, txHash, data }` wrapper object.
