deps(contracts)(deps-dev): bump hardhat from 2.28.6 to 3.4.0 in /packages/contracts

[dependabot]

Bumps hardhat from 2.28.6 to 3.4.0.

Release notes

Sourced from hardhat's releases.

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

If you compile your project with the production Build Profile, a new toolVersions field containing the Hardhat version will be added to your Build Info files. This can help you reproduce your builds in the future.

You can enable this functionality in other build profiles with the flag toolVersionsInBuildInfo.

Smaller Build Info output files by using a better default output selector

Building your contracts with this version of Hardhat will lead to a significantly smaller artifacts/ folder, in some cases around 50% smaller.

User migration guide

To update to this new version of Hardhat, please follow this guide.

Replace network.connect() with network.create().

Replace network.connect(...) calls with network.create(...). Everything else keeps working as expected.

Build ids may change even when bytecode is identical

• #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.

  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.

• #8114 6eeb144 Thanks @​ChristopherDedominici! - Updated forking configurations to support number and bigint.

• #8121 0f1038c Thanks @​alcuadrado! - Update the default outputSelection setting of solc to decrease the artifacts size.

  NOTE: This change can lead to build info ids changing, despite compilation output's bytecodes being identical.

• #8122 edfa548 Thanks @​alcuadrado! - Optimize hre.artifacts.artifactExists()

• #8115 935a043 Thanks @​ChristopherDedominici! - Breaking change: removed timeout option for Solidity tests in hardhat.config.ts file.
