pragma solidity ^0.8.0;

contract OwnerControlled {
    address public owner;
    uint256 private value;

    event ValueChanged(uint256 newValue);
    error Unknown(string str);

    constructor() {
        owner = msg.sender;
    }

    modifier onlyOwner() {
        if(msg.sender != owner) {
            revert Unknown("only Owner");
        }
        _;
    }

    function setValue(uint256 _newValue) public onlyOwner {
        value = _newValue;
        emit ValueChanged(_newValue);
    }

    function getValue() public view returns (uint256) {
        return value;
    }
}

in this contract, when tx revert by using custom error.
cast run result:

Executing previous transactions from the block.
Traces:
  [2462] 0xDc64a140Aa3E981100a9becA4E685f962f0cF6C9::setValue(1)
    └─ ← [Revert] custom error 7c45b126: 
only Owner


Transaction failed.

Solution

I think we can make it more readable by using openchain's signature database online.
In this pr, custom err would look like:

Executing previous transactions from the block.
Traces:
  [2462] 0xDc64a140Aa3E981100a9becA4E685f962f0cF6C9::setValue(1)
    └─ ← [Revert] Unknown("only Owner")


Transaction failed.
