Release notes

Sourced from hardhat's releases.

Hardhat v3.18.1

This is a small bugfix release with fixes for simulated network predeploys and Solidity test error formatting.

Changes

• #8631 d014d43 Thanks @​Kropiunig! - Fixed edr-simulated networks with forking.enabled: false starting without the chain's predeploys (e.g. OP's GasPriceOracle and L1Block, or the L1 beacon roots and history storage contracts).

• #8636 8b24451 Thanks @​schaable! - Fixed the formatting of errors reported while running Solidity tests.

• Updated dependencies:

  • @​nomicfoundation/hardhat-utils@​4.4.0

---

💡 The Nomic Foundation is hiring! Check our open positions.

Hardhat v3.18.0

This release includes two enhancements along with performance improvements and bug fixes: test profiles can now be used in Solidity tests, see our test profiles guide, and hardhat-mocha has been updated to mocha@12.

Changes

• #8590 e2ebf54 Thanks @​schaable! - Added Solidity test profiles, allowing test settings to vary across environments such as local development and CI.

• #8595 562cc0b Thanks @​ChristopherDedominici! - Made ethers derive secp256k1 public keys with EDR's native implementation instead of its pure-JS one, speeding up new Wallet(secretKey), Wallet.createRandom(), HD wallet derivation and computeAddress.

• #8624 1377eb0 Thanks @​ChristopherDedominici! - Updated mocha to ^12.0.0 in the hardhat --init mocha-ethers template project.

• #8574 e28e4f5 Thanks @​anaPerezGhiglia! - Removed the pre-Byzantium hardforks (chainstart, homestead, dao, tangerineWhistle, spuriousDragon) from the accepted hardfork and hardforkHistory values, as EDR cannot execute them.

• #8635 ad92657 Thanks @​popescuoctavian! - Upgraded EDR to v0.22.0.

• #8601 34087dd Thanks @​cdesch! - Improved HTTP proxy support.

• #8616 8b73917 Thanks @​rome-xi! - Fixed invalid HTTPS_PROXY/HTTP_PROXY values being reported as unexpected errors instead of a Hardhat error.

• Updated dependencies:

  • @​nomicfoundation/hardhat-errors@​3.1.0
  • @​nomicfoundation/hardhat-utils@​4.3.0

Hardhat v3.17.0

This release includes a new default gas estimation mode for eth_estimateGas to prevent misleading results when internal calls run out of gas, as well as improved performance for test suites using ethers.

Changes

• #8501 5faee42 Thanks @​ChristopherDedominici! - Add gasEstimationMode config option to EDR networks, defaulting to a new "noInternalOutOfGas" mode to prevent misleading eth_estimateGas results when internal calls run out of gas.
