Unknown key "viaIR"

Question

Unknown key "viaIR" Error HH600: Compilation failed

I'm encountering the above error when I try to compile.

Here is my hardhat.config.ts

import { HardhatUserConfig } from "hardhat/config";
import "@nomicfoundation/hardhat-toolbox";

const config: HardhatUserConfig = {
  solidity: {
    version: "0.6.12",
    settings: {
      viaIR: true,
    },
  },
};

export default config;

Answer 1

viaIR: true may require version 0.8.13 and higher.
