Quick start

Update for Shagnhai EVM features

1. PUSH0 opcode

You can use shanghai evm version in your project.

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.20;
contract MetisShanghaiUpgradeExample {
    uint256 public num;
    function push0(uint256 _n) public {
        num = _n;
    }
}

2. More user-friendly error from the rpc

The RPC can return encoded custom errors and solidity panic errors

Custom errors

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.20;
error MyError();
contract MetisShanghaiUpgradeExample {
    function customError() public pure {
        revert MyError();
    }
}

curl https://l2rpc.devnet.metisdevops.link -X POST -H "Content-Type: application/json" \
  --data '{"method":"eth_call","params":[{"to":"0x2e07967571dB8896178A65039b4Dd13Be354B002","input":"0xdda3a7bd"}, "latest"],"id":1,"jsonrpc":"2.0"}'

The error data 0xdd6c951c is for the custom error MyError

{
  "jsonrpc": "2.0",
  "id": 1,
  "error": { "code": 3, "message": "execution reverted", "data": "0xdd6c951c" }
}

Solidity panic errors

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.20;
contract MetisShanghaiUpgradeExample {
    function panicError(uint256 _x) public pure returns (uint256){
        return _x / 0;
    }
}

curl https://l2rpc.devnet.metisdevops.link -X POST -H "Content-Type: application/json" \
  --data '{"method":"eth_call","params":[{"to":"0x2e07967571dB8896178A65039b4Dd13Be354B002","input":"0x67c9d7930000000000000000000000000000000000000000000000000000000000000001"}, "latest"],"id":1,"jsonrpc":"2.0"}'

{
  "jsonrpc": "2.0",
  "id": 1,
  "error": {
    "code": 3,
    "message": "execution reverted: division or modulo by zero",
    "data": "0x4e487b710000000000000000000000000000000000000000000000000000000000000012"
  }
}
