This newsletter is made possible thanks to Hardhat’s VSCode extension!

The Hardhat for Visual Studio Code extension adds comprehensive language support for Solidity to Visual Studio Code and enhances editor integration for Hardhat projects.

Key features include code completion, go to definition, symbol renaming, and inline code validation from compiler errors/warnings. 

The extension also provides helpful code actions, hover help, and support for adding access modifiers and virtual/override keywords to function signatures.
