波场(Tron)发币教程
免手续费,易上手,直接发行和定制属于自己的波场链代币
什么是 TRC-20 代币
波场链上有两种同质化代币标准:TRC-10 和 TRC-20
TRC-10 代币是波场原生代币标准,不依赖智能合约,直接在链上发行。发行成本低,交易速度快,手续费低廉(仅消耗带宽和能量),功能简单,仅支持基础转账和余额查询。常用于简单资产发行(如社区代币、积分)等低复杂度应用场景。
TRC-20 代币类似以太坊的 ERC-20,基于智能合约的标准化代币。支持复杂功能(如授权转账、代币销毁等),交易需要消耗 TRX 作为手续费(Gas)。常用于 DeFi 代币(如稳定币、治理代币)等。
通常说到波场链的代币,未特殊说明的话,都是默认指 TRC-20 的代币标准。本文的发币教程也核心针对 TRC-20 代币标准进行演示说明。
标准 TRC-20 代币指的是没有任何功能、机制的代币合约,代币创建之后默认会丢弃权限,所以也没有任何权限,是一个纯粹的、干净的、标准的合约。
根据以下步骤,您可以在 Tron 上创建一个属于自己的标准合约代币。
部署准备
钱包:TronLink,保证钱包中至少有 150 个 TRX,用于支付代币部署的 gas 费用

部署流程
打开合约部署的页面:https://tronscan.org/#/contracts/contract-compiler,点击页面右上角进行钱包连接
点击上传按钮,将前面从 github 下载的合约代码(trc20.sol)进行上传
合约上传成功之后即可在页面中看到合约的代码
点击编译按钮
这里我们启用优化配置,可以帮助我们部署的时候更节省 gas,然后点击 Confirm 进行确认 如果看到下面这几行绿色的信息,即表示合约代码编译通过,准备开始部署
下面开始点击部署,开始相关代币参数的配置
首先要么要选择 CpboxTRC20Token 这个合约,选择之后可以看到最下面的代币信息填写区域: tokenName:代币的名称
tokenSymbol:代币的符号
tokenDecimals:代币的小数点
tokenSupply:代币的供应量,假设我们总共的代币供应量为 10000,decimal 为 18 位,那么这里的 initialSupply 的供应量就需要填 10000000000000000000000 = 10000 * 10^18(10000 乘以 10 的 18 次方)
以下是一份供应量为 10000 个 CDT 代币的示例配置:
点击 Confirm 进行确认,即可唤起 TronLink 钱包,将合约部署的交易发到链上(注意要保证有充足的 TRX 进行 gas 费用的支付)
交易确认成功之后即代币部署成功。
上面介绍了波场链(Tron)上部署代币的方式,如果你觉得太麻烦也可以选择 CPBOX 发币,支持多个主网
