verfication failed

Environment information

• brownie Version: 1.14.6
• solc Version: 0.8.4
• Python Version: 3.9.4
• OS: linux

What was wrong?

Given a contract

// contracts/hodl.sol
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "OpenZeppelin/openzeppelin-contracts@4.0.0/contracts/utils/Context.sol";
import "OpenZeppelin/openzeppelin-contracts@4.0.0/contracts/token/ERC777/ERC777.sol";

contract TestToken is ERC777 {
    constructor() ERC777("Test Token", "TEST", new address[](0)) {
        _mint(msg.sender, 1e25, "", "");
    }
}

brownie compile runs perfect. But in brownie console, verification always fails using either deploy() or publish_source().

How can it be fixed?

I don’t know how to fix this.

I have the same issue. Using solc 0.8.3 instead of 0.8.4 seems to have fixed. Guessing this is related to the issue that makes coverage reports fail on 0.8.4
