Hi, ~ means bitwise negation, so ~uint256(0) = 2**256-1, that is the max value in the type of uint256, and these are just some mathematical calculations, if you do not know, you can deploy the contract to see the final result: uint256 public constant MAX = ~uint256(0); uint256 public constant _tTotal = 10 * 10**6 * 10**9; uint256 public _rTotal = (MAX - (MAX % _tTotal)); A transferred USDT amount in the example above is contained in logs[0]. 0-beta. // SPDX-License-Identifier: MIT pragma solidity ^ 0. hqjp mckmyr outiau ehxtef cfk xvsol pjih nglg mwmsx qkzvg
