为部署在 RinkeBy 测试网上的智能合约执行 ERC20 代币 'transfer function' 的原始交易

Question

我正在尝试使用 ERC20 传输函数将余额从合约部署者地址转移到另一个地址。

从部署者地址进行本地 Ganache 网络传输非常简单

await contract.transfer(receiverAddress, amount);

由于 Rinkeby Testnet 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。执行下面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：我可以查看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);

Answer 1

转账时需要与合约进行交互（即向合约发送交易）。不直接与令牌接收者一起使用。

所以需要将交易的to字段改为合约地址。

// 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
};
