为部署在 RinkeBy 测试网上的智能合约执行 ERC20 代币“转移功能”的原始交易

如何解决为部署在 RinkeBy 测试网上的智能合约执行 ERC20 代币“转移功能”的原始交易

我正在尝试使用 ERC20 转移功能将余额从合约部署者地址转移到另一个地址。

对于本地 Ganache 网络从部署者地址传输就像

await contract.transfer(receiverAddress,amount);

由于 Rinkeby 测试网不允许使用方法“eth_sendTransaction”并给出错误，因此我尝试创建如下所示的原始交易。执行以下编写的代码时没有收到错误，但接收方的余额也没有变化。

const result = {};
const contract = new web3.eth.Contract(token_artifact.abi,config.contractAddress);
const count = await web3.eth.getTransactionCount(config.deployerAddress);

const nonce = web3.utils.toHex(count);
const gasLimit = web3.utils.toHex(90000);
const gasPrice = web3.utils.toHex(web3.eth.gasPrice || web3.utils.toHex(2 * 1e9));
const value = web3.utils.toHex(web3.utils.toWei('0','wei'));
const data = contract.methods.transfer(receiver,amount).encodeABI();

const txData = {
      nonce,gasLimit,gasPrice,value,data,from: config.deployerAddress,to: receiver
     };

web3.eth.accounts.wallet.add(config.deployerPrivateKey);
const sentTx = await web3.eth.sendTransaction(txData);
result['receipt'] = sentTx;

    }
}

[注意：我可以检查给定地址的总供应量和余额。]

let data = {};
const contract = require('@truffle/contract');
const Token = contract(token_artifact);
Token.setProvider(web3.currentProvider);

const instance = await Token.at(config.contractAddress);

const result = await Promise.all([instance.totalSupply(),instance.balanceOf(address)]);
data['totalSupply'] = result[0].toNumber();
data['balanceOf'] = result[1].toNumber();

resolve(data);

解决方法

在转移代币时，您需要与合约进行交互（即向合约发送交易）。不直接与令牌接收器。

因此您需要将交易的to字段更改为合约地址。

// this field says that you want to transfer tokens to the `receiver`
const data = contract.methods.transfer(receiver,amount).encodeABI();

const txData = {
      nonce,gasLimit,gasPrice,value,data,// containing info that you want to `transfer()` to the `receiver`
      from: config.deployerAddress,// send transaction from your address
      to: config.contractAddress // CHANGED; send transaction to the contract address
};
