solidity | solidity 大小写

这里针对 solidity 的大小写进行比较。

pragma solidity ^0.8.0;
interface functionContract {

function token0() external view returns (address);
    function token1() external view returns (address);
}

contract FlashSwap {

function checkToken1(address _pair,address token) public view returns(bool){
        return token == functionContract(_pair).token0();
    }
}

这里针对各种 dex 的 token0 的比较。

经过验证，以下两种形式可以

  • 0x3d6545b08693daE087E957cb1180ee38B9e3c25E
  • 0x3d6545b08693dae087e957cb1180ee38b9e3c25e

纯大写不行

  • 0X3D6545B08693DAE087E957CB1180EE38B9E3C25E
