Bumps hardhat from 2.22.19 to 3.19.0.

Release notes

Sourced from hardhat's releases.

Hardhat v3.19.0

This release expands our support for the upcoming Amsterdam hardfork, including: EIP-7976, EIP-7981, EIP-7997, EIP-8024 and EIP-8037. In particular, EIP-8037's separation of execution gas and state gas metering significantly changes the gas costs of state creation, so test early. See our Amsterdam Support guide for more details.

Changes

  • #8680 0e51fa2 Thanks @​anaPerezGhiglia! - Added experimental EIP-7976 support to the Amsterdam hardfork: the calldata floor cost rises to 64 gas per byte. See the guide for more details.

  • #8680 b52d2eb Thanks @​anaPerezGhiglia! - Added experimental EIP-7981 support to the Amsterdam hardfork: access list data costs an extra 64 gas per byte. See the guide for more details.

  • #8680 bb62bf6 Thanks @​anaPerezGhiglia! - Added experimental EIP-7997 support to the Amsterdam hardfork: the deterministic CREATE2 factory is now part of the genesis state. See the guide for more details.

  • #8680 0e51fa2 Thanks @​anaPerezGhiglia! - Added experimental EIP-8024 support to the Amsterdam hardfork: the DUPN, SWAPN and EXCHANGE opcodes reach stack items beyond DUP16 and SWAP16. See the guide for more details.

  • #8680 bb62bf6 Thanks @​anaPerezGhiglia! - Added experimental EIP-8037 support to the Amsterdam hardfork: execution gas and state gas are metered separately, and a block's gasUsed reports the larger. See the guide for more details.

  • #8680 bb62bf6 Thanks @​anaPerezGhiglia! - Upgraded EDR to v0.22.2.

  • #8679 63fb54a Thanks @​Wodann! - Excluded the templates' node_modules folders from the published package, which broke installation with Yarn classic.

  • #8667 5793554 Thanks @​schaable! - Improved the errors for invalid transactions sent from local accounts.

  • #8666 0295fef Thanks @​schaable! - Fixed locally managed accounts silently dropping the blobs of EIP-4844 transactions; sending one now throws an error.

  • #8680 17133ce Thanks @​kanej! - Removed the remaining built-in Holesky (chain ID 17000) hardfork history, as the network has been shut down.

  • #8680 17133ce Thanks @​kanej! - Added the Amsterdam hardfork activation on Sepolia, so forking Sepolia uses amsterdam for blocks after it activates.

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.

3.18.0

Minor Changes

  • #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.

  • #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.

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