Bump hardhat from 2.6.0 to 2.10.2 in /examples/hardhat

[dependabot]

Bumps hardhat from 2.6.0 to 2.10.2.

Release notes

Sourced from hardhat's releases.

Hardhat v2.10.2

This version adds support for Solidity versions up through 0.8.16. Besides that:

• Now console.log() prints an empty line instead of printing undefined.
• The "Unrecognized custom error" message includes the selector of the custom error.

Hardhat v2.10.1

This version improves how propagated Solidity errors are processed by Hardhat (issue #2546).

Hardhat 2.10.0: A refreshed experience

Hardhat 2.10.0 is out, and it marks a change in the product direction that Hardhat has historically taken.

Hardhat’s core values have always been optionality, flexibility and extensibility, enabling it to be used in whatever ways were needed and found to be useful. However, as we described in this thread, the Ethereum and Hardhat development ecosystems grew too large for easy navigation among the many different paths and viable options.

While retaining those core values, Hardhat 2.10.0 now offers a complete and opinionated setup that is ready to start building Ethereum software out-of-the-box. No decisions on plugins, libraries, or dependencies. Just get going.

We’re calling this the Hardhat Toolbox, which is a bundle of plugins and functionality that the Nomic Foundation team considers to be the best way to get started with a new Ethereum project. Read on to learn more about it.

Hardhat Toolbox

You can get our recommended setup by installing the @nomicfoundation/hardhat-toolbox plugin.

When you use this plugin, you'll be able to:

• Deploy and interact with your contracts using ethers.js and the hardhat-ethers plugin.
• Test your contracts with Mocha, Chai and our own Hardhat Chai Matchers plugin.
• Interact with Hardhat Network with our Hardhat Network Helpers.
• Verify the source code of your contracts with the hardhat-etherscan plugin.
• Get metrics on the gas used by your contracts with the hardhat-gas-reporter plugin.
• Measure your tests coverage with solidity-coverage.
• And, if you are using TypeScript, get type bindings for your contracts with Typechain.

You can learn how to migrate to it here.

Hardhat Chai Matchers

@nomicfoundation/hardhat-chai-matchers is a drop-in replacement of @nomiclabs/hardhat-waffle that integrates more tightly with Hardhat, adds new functionality and improves its error messages. We recommend migrating to it.

Since the very beginning, we’ve recommended that people use Waffle, via hardhat-waffle, and we thank the team at TrueFi for their great work. However, for such a core component of the setup, there were too many recurring issues related to not being integrated deeply enough with Hardhat. For this reason, we decided to fork Waffle and release our own Chai matchers.

Some of its functionality and improvements:

• All of hardhat-waffle’s matchers are supported
• Great support for BigNumber and native bigint
  • No need to think about them anymore
  • Our matchers can compare any combination of
    • number
    • Native bigint
    • ethers.BigNumber
    • BN.js
