This newsletter is made possible thanks to Hardhat!

Hardhat has just released a refreshed experience for new projects: Hardhat Toolbox. With minimal boilerplate and set up effort, it’s the best way to get started with building for Ethereum.

Hardhat Toolbox packs most of the functionality you’ll need into a single package. No additional plugins required to get started. It also includes a new replacement for hardhat-waffle that is tightly integrated with Hardhat which offers extra features and better error messages.

Check out the announcement for more information, and install Hardhat 2.10.0 to try it out!
