使用golang 将ETH账户的资产汇集到一个账户

首先安装依赖插件

go mod init test
#复制下面代码放入 test.go 然后执行：
go mod tidy

下面是一段golang代码展示汇集eth的示例，请把私钥等配置成自己的

package main

import (
	"encoding/hex"
	"fmt"
	"github.com/yellomoon/web3tool"
	"github.com/yellomoon/web3tool/jsonrpc"
	"github.com/yellomoon/web3tool/wallet"
	"math"
	"math/big"
	"sync"
)

var RpcClient *jsonrpc.Client
var mut sync.Mutex

// var rpcUrl = "https://eth-mainnet.public.blastapi.io" // RPC URL  如果地址不能使用了 请去 https://infura.io 注册账号获取免费的
var rpcUrl = "http://localhost:7545"

func getClient() *jsonrpc.Client {
	mut.Lock()
	defer mut.Unlock()
	var err error
	if RpcClient == nil {
		RpcClient, err = jsonrpc.NewClient(rpcUrl)
		if err != nil {
			panic(err)
		}
	}
	return RpcClient
}

/*
获取指定账户的eth余额
address: 指定账户地址

:return:账户余额
*/
func getEthBalance(address string) *big.Int {
	client := getClient()
	number, err := client.Eth().BlockNumber()
	if err != nil {
		panic(err)
	}
	balance, e := client.Eth().GetBalance(web3tool.HexToAddress(address), web3tool.BlockNumber(number))
	if e != nil {
		panic(e)

	return balance
}
