TRC20 是一种基于 TRON 区块链的代币标准，类似于以太坊的 ERC20 标准。TRC20 代币合约的代码能让用户在 TRON 网络上创建和管理自己的代币。以下是一个简单的 TRC20 代币合约示例代码，您可以根据自己的需求进行修改和扩展。 ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.5.0; contract TRC20Token { string public name; string public symbol; uint8 public decimals = 18; uint256 public totalSupply; mapping(address = uint256) public balanceOf; mapping(address = mapping(address = uint256)) public allowance; event Transfer(address indexed from, address indexed to, uint256 value); event Approval(address indexed owner, address indexed spender, uint256 value); constructor(string memory _name, string memory _symbol, uint256 _initialSupply) public { name = _name; symbol = _symbol; totalSupply = _initialSupply * (10 ** uint256(decimals)); balanceOf[msg.sender] = totalSupply; // 将所有初始代币分配给合约的创建者 } function transfer(address _to, uint256 _value) public returns (bool success) { require(_to != address(0), TRC20 是一种基于 TRON 区块链的代币标准，类似于以太坊的 ERC20 标准。TRC20 代币合约的代码能让用户在 TRON 网络上创建和管理自己的代币。以下是一个简单的 TRC20 代币合约示例代码，您可以根据自己的需求进行修改和扩展。 ```solidity // SPDX-License-Identifier: MIT pragma solidity ^0.5.0; contract TRC20Token { string public name; string public symbol; uint8 public decimals = 18; uint256 public totalSupply; mapping(address = uint256) public balanceOf; mapping(address = mapping(address = uint256)) public allowance; event Transfer(address indexed from, address indexed to, uint256 value); event Approval(address indexed owner, address indexed spender, uint256 value); constructor(string memory _name, string memory _symbol, uint256 _initialSupply) public { name = _name; symbol = _symbol; totalSupply = _initialSupply * (10 ** uint256(decimals)); balanceOf[msg.sender] = totalSupply; // 将所有初始代币分配给合约的创建者 } function transfer(address _to, uint256 _value) public returns (bool success) { require(_to != address(0),
