💥 Plugin name

hardhat-zksync-solc

📝 Description

It would be useful if solidity compilation would work using the cached compiler offline.

🤔 Rationale

A colleague from Avara asked about offline compilation of Solidity code using hardhat. This is useful when working with (temporarly) no internet access, for example during flights.

  errno: -3008,
  code: 'ENOTFOUND',
  syscall: 'getaddrinfo',
  hostname: 'github.com'
