Contract 를 활용한 transfer 호출시 revert error 문의

[namu]

답변 감사합니다!

traceTransaction 을 통한 debugging 은 상당히 어렵네요.
아래는 traceTransaction 을 실행한 결과 입니다.

이 외에 여러가지 방법을 찾아보다가 해결이 되었는데요, 아래와 같이 solidity 코드를 수정하고 해결이 되었습니다.

function test(address recipient, address token, uint256 amount) public returns (bool) {
    (bool success, bytes memory data) = token.delegatecall(abi.encodeWithSignature("transfer(address,uint256)", recipient, amount));
    return success;
}

기본적으로 solidity compiler 가 method 호출을 call 로 compile 하여, 기대했던 msg.sender 값이 실제와 달랐던 것 같아요.
