custom-solc

Using a custom solc

To use a custom solc you need to override the TASK_COMPILE_SOLIDITY_GET_SOLC_BUILD subtask. This subtask returns an object with four properties:

• compilerPath: the path to the compiler
• isSolcJs: a flag indicating if the compiler is a javascript module or a native binary
• version: the short version of the compiler (for example, 0.8.5)
• longVersion: the long version of the compiler (for example, 0.8.5-nightly.2021.5.12+commit.98e2b4e5). This property is used as extra metadata in the build-info files, so you shouldn't worry too much about its value.

See hardhat.config.js to see how it's done.
