MetaMask - RPC错误:错误: 0.001号的事务值无效必须在wei中

Question

我希望使用MetaMask发送ETH或ERC20令牌

下面的脚本是抛出错误，

RPC错误:错误: 0.001号的事务值无效，必须在wei中。

const method = 'eth_sendTransaction'
const parameters = [{
    from: account,
    to: to,
    value: 0.001
}]
const from = account
const payload = {
    method: method,
    params: parameters,
    from: from,
}
web3.currentProvider.sendAsync(payload, function (err, response) {

}); 

Answer 1

In Ether, the smallest unit of the currency is wei, and 1 ETH === 10^18 wei 

var weiValue = web3.utils.toWei('1'，‘醚’)；// 1醚 console.log(weiValue);//1000000000000000000

Answer 2

MetaMask不再注入web3。有关详细信息，请参阅：https://docs.metamask.io/guide/provider-migration.html#replacing-window-web3
