Feature Request

As a follow-up to https://github.com/web3/web3.js/issues/4235 implements more tests (and replace the current one). Additionally, some cases need to be handled. According to: https://blog.soliditylang.org/2021/04/21/custom-errors/ there are special selectors: 0x82b42900 which is the ‘selector’ for Unauthorized() and 0x08c379a0 is the ‘selector’ of Error(string).

Use Cases

Deploying a smart contract locally enables better testing. And handling for Unauthorized() and Error(string) would be good as they are special selectors that the user would not need to provide the ABI for.

0x82b42900/Unauthorized() is not a special selector. It's just an example of a user-defined error, it's shown in Example section in the article linked.

The two built in selectors are Error(string) and Panic(uint256) as defined in the docs.
