This Hardhat 3 Alpha release adds support for Blockscout to the hardhat-verify plugin and overhauls how dependency resolution and remappings work.
Improved support for remappings
Hardhat now supports remappings.txt files in your project, as well as in git submodules and npm dependencies.
Each remappings.txt file applies to the directory where it's located and all its subdirectories, similar to how .gitignore works.
This version also removes support for defining remappings directly in your solidity config. Please migrate to using remappings.txt files instead.
Additionally, remapping targets for npm packages have changed. Previously, these targets used the format npm/<package>@<version>/.... They now follow the structure node_modules/<package>/..., which is simpler and better aligned with the rest of the ecosystem.
