如果我只知道合同地址和合同接口(ABI),我试图找出是否可以获取合同创建者的地址吗?
答案 0 :(得分:1)
没有用于查找合同创建者地址的显式web3.js方法。如果要使用web3.js完成此操作,则必须从本质上遍历所有先前的块和交易,然后再通过web3.eth.getTransactionReceipt
搜索交易收据。这将返回一个contractAddress
属性,该属性可以与您拥有的合同地址进行比较。
以下是使用web3.js(v1.0.0-beta.37)的示例:
const contractAddress = '0x61a54d8f8a8ec8bf2ae3436ad915034a5b223f5a';
async function getContractCreatorAddress() {
let currentBlockNum = await web3.eth.getBlockNumber();
let txFound = false;
while(currentBlockNum >= 0 && !txFound) {
const block = await web3.eth.getBlock(currentBlockNum, true);
const transactions = block.transactions;
for(let j = 0; j < transactions.length; j++) {
// We know this is a Contract deployment
if(!transactions[j].to) {
const receipt = await web3.eth.getTransactionReceipt(transactions[j].hash);
if(receipt.contractAddress && receipt.contractAddress.toLowerCase() === contractAddress.toLowerCase()) {
txFound = true;
console.log(`Contract Creator Address: ${transactions[j].from}`);
break;
}
}
}
currentBlockNum--;
}
}
getContractCreatorAddress();
