区块链浏览器上做合约验证,部署的时候用的多文件

多个文件验证不可控因素有点多,你用truffle-flatten做成一个文件,然后使用remix部署,然后再验证,就是单个文件验证,直接复制remix里的代码,比较顺利

How to check if Ethereum address is valid or not

web3.js

const address = "0x0089d53F703f7E0843953D48133f74cE247184c2"
let result = Web3.utils.isAddress(address)
console.log(result)  // => true

web3j

社区fork为其增加了isAddress commit
https://github.com/bcskill/web3j

package org.web3j.utils;

import org.junit.Test;

import static junit.framework.TestCase.assertFalse;
import static org.junit.Assert.assertTrue;

import static org.web3j.utils.Account.isAddress;

public class AccountTest {
    @Test
    public void verifyIsAddress() {
        String validLowerCaseAddress = "0x3de8c14c8e7a956f5cc4d82beff749ee65fdc358";
        assertTrue(isAddress(validLowerCaseAddress));
        String validChecksumAddress = "0xfB6916095ca1df60bB79Ce92cE3Ea74c37c5d359";
        assertTrue(isAddress(validChecksumAddress));
        String invalidLengthAddress = "0x3de8c14c8e7a956f5cc4d82beff749ee65bac35";
        assertFalse(isAddress(invalidLengthAddress));
        String invalidChecksumAddress = "0x3de8c14c8E7a956f5cc4d82beff749ee65fdc358";
        assertFalse(isAddress(invalidChecksumAddress));
    }
}
