Bumps hardhat from 2.27.0 to 3.4.1.

Release notes

Sourced from hardhat's releases.

hardhat@3.4.1

This change includes small performance improvements and bug fixes. Note that node:test test suites now run sequentially, matching the the mocha testing plugin.

Changes

• #8142 a997091 Thanks @​ChristopherDedominici! - Make node:test sequential by default and run test files in the same process (isolation: "none").
• #8173 1a01f9b Thanks @​alcuadrado! - Improve error reporter
• #8176 13e46b2 Thanks @​kanej! - Fixed compilation error check to ignore ambiguous warnings (#8176)
• #8179 d16d82a Thanks @​alcuadrado! - Await all returned promises for better debuggability
• Updated dependencies:
  • @​nomicfoundation/hardhat-utils@​4.0.4

Hardhat v3.4.0

This is a large release in preparation of the first stable version of Hardhat 3!

Please read the list of changes below, the user migration guide, and if you are a plugin author, the plugins migration guide.

Highlights

New NetworkManager methods

We deprecated the network.connect() method as it was a common source of confusion. It still works, but will eventually be removed.

Instead, you can use the new methods network.create() and network.getOrCreate().

Unified compilation of contracts and Solidity tests

Previously, Hardhat 3 compiled your contracts and your Solidity tests independently. Starting with this version, they are built together, leading to faster compilation times and smaller compilation artifacts.

You can opt into the older behavior with the new splitTestsCompilation field in your solidity config. This is mainly useful if you rely on plugins that don't yet support unified compilation yet, or if your setup depends on test artifacts being isolated from contract artifacts.

Simulated networks now return the JSON-RPC code 3 on execution errors

If you run an in-process simulated network, or hardhat node, revert errors in JSON-RPC responses now use code 3 instead of the code used previously (-32603 or no code at all). This change aligns Hardhat's behavior with the rest of the tooling ecosystem.

This should only improve the error messages that you see, and doesn't require any update, unless you are manually interacting with JSON-RPC responses.

Proxies support in the --gas-stats feature

Hardhat now classifies gas stat entries based on both the implementation contract and the proxy (or proxies) in front of it. For example, a proxy forwarding to a Vault contract is now reported as gas spent in Vault via the proxy.

Previously, that same call would have reported all the gas under the proxy, hiding which implementation actually did the work.

The Hardhat version is now included in the BuildInfo files of production builds

Minor Changes

• #8116 88787e1 Thanks @​kanej! - Add getOrCreate to the network API

• #8127 353cf86 Thanks @​alcuadrado! - Make the split of contracts and solidity tests compilation optional, and controlled with a new splitTestsCompilation config field.

Patch Changes

• #8105 00e9695 Thanks @​marianfe! - Add Solidity 0.8.34 to the default EVM targets table (osaka) (#8105)

• #8108 5404ac8 Thanks @​schaable! - Display contract runtime bytecode size in the gas stats table and JSON output

• #8104 e27a7ad Thanks @​ChristopherDedominici! - Use code 3 for JSON-RPC revert error codes to align with standard node behavior and preserve error causes in viem/ethers.

• #8103 14b335a Thanks @​kanej! - Improved network handler performance through additional metadata to allow early skipping (#8103)

• #8148 49ec5d0 Thanks @​alcuadrado! - Don't report HardhatErrors that aren't bugs

• #8102 d5f8394 Thanks @​kanej! - Improved performance of network handler initialization (#8102)

• #8141 63c68c1 Thanks @​ChristopherDedominici! - Added support for EDR structured Solidity test cheatcode errors.

• #8123 cf3933b Thanks @​alcuadrado! - Add a toolVersionsInBuildInfo setting to the Solidity config, which is true by default in the production build profile. When enabled, the version of Hardhat is included in the Build Info files.

  NOTE: This change can lead to build info ids changing despite the compilation output's bytecodes being identical, especially when using the production build profile.

• #8143 f74cec9 Thanks @​ChristopherDedominici! - Update .gitignore files in the sample projects to ignore snapshots and env files.

• #8096 7fb721b Thanks @​alcuadrado! - [chore] Move to packages/ folder.

• #8116 88787e1 Thanks @​kanej! - Deprecate the hre.network.connect() method in favour of hre.network.create(), exactly the same method but more clearly indicating that it will create a new connection.

• #8119 ff5a97e Thanks @​schaable! - Show proxy chain information in --gas-stats and --gas-stats-json output
