build(deps-dev): bump @nomicfoundation/hardhat-toolbox from 2.0.2 to 4.0.0

[dependabot]

Bumps @nomicfoundation/hardhat-toolbox from 2.0.2 to 4.0.0.

Release notes

Sourced from @​nomicfoundation/hardhat-toolbox's releases.

@​nomicfoundation/hardhat-toolbox@​4.0.0

This version of Hardhat Toolbox bumps the versions of hardhat-verify and typechain. This is a new major because the new versions of those peer dependencies are not compatible with the previous ones, but you can consider this a low-risk upgrade.

Hardhat Toolbox v3.0.0: ethers v6, bigints and more!

This new major version of Hardhat Toolbox is based on ethers v6 and uses new versions of the hardhat-ethers, hardhat-chai-matchers and typechain plugins.

Using in a new project

Nothing has changed in how you use the Toolbox for a new project: if you initialize one with the latest version of Hardhat, then this version of the Toolbox will be used. Check our Setting up a project guide for the complete instructions.

Upgrading an existing project

To use this new version of the Toolbox in an existing project, you need to upgrade the Toolbox and its relevant peer dependencies.

If you are using npm 7 or later, you just need to upgrade the Toolbox and npm will handle the rest:

npm install @nomicfoundation/hardhat-toolbox@3

If you are using yarn or an older version of npm, you’ll need to manually upgrade all the relevant packages and remove the ones that are no longer needed:

# upgrade relevant packages
yarn add @nomicfoundation/hardhat-toolbox@3 @nomicfoundation/hardhat-chai-matchers@2 @nomicfoundation/hardhat-ethers@3 @nomicfoundation/hardhat-verify @typechain/ethers-v6 @typechain/hardhat@8 ethers@6
remove packages that are no longer needed
yarn remove @​ethersproject/abi @​ethersproject/providers @​nomiclabs/hardhat-ethers @​nomiclabs/hardhat-etherscan @​typechain/ethers-v5

What’s new?

Ethers v6 has several changes with respect to v5. These are some of them, but check their migration guide for the full details.

Native bigints

One of the most important changes in v6 is that now native bigints are used instead of BigNumber objects. For example, checking if an address has a positive amount of tokens is done like this in v5:

const balance = await token.balanceOf(someAddress)
if (balance.gt(0)) {
// ...
}

While in v6 you would do it this way:

const balance = await token.balanceOf(someAddress)
</tr></table>
