我正在使用 web3 库版本 0.20.2。我想用我的智能合约做的只是转移自定义的 erc20 代币。
下面的智能合约代码(sloidity)
function transfer(address _to, uint256 _value) returns (bool success) {}
我想使用此功能将我的自定义令牌转移到 _to(地址)。
var myContract = web3.eth.contract(abi)
var myContractInstance = myContract.at(address);
var total = myContractInstance.totalSupply();
var balance = myContractInstance.balanceOf(owner);
onsole.log('total',total);
console.log('balance',balance);
var to ="0x20....";
var value = 10;
var isAddress = web3.isAddress(to);
console.log(isAddress);
myContractInstance.transfer(to, value, (err,res)=> {console.log(err,res);});
这是我的控制台。

我不知道怎么了,我错过了什么吗?请让我知道如何解决此“无效地址”错误。谢谢!
