使用Go语言创建Polygon公链钱包地址

生成Polygon公链钱包地址

Polygon是建立在以太坊上的Layer2解决方案，私钥、公钥、地址生成原理和以太坊一样。

package main

import (
	"crypto/ecdsa"
	"fmt"

	"github.com/ethereum/go-ethereum/common/hexutil"
	"github.com/ethereum/go-ethereum/crypto"
)

func main() {
	ad, pk := generateKeyPair()
	fmt.Printf("%s\n%s\n", ad, pk)
}

func generateKeyPair() (ad, pk string) {
    // 生成私钥：生成一个随机的椭圆曲线数字签名算法（ECDSA）私钥
	privateKey, _ := crypto.GenerateKey()
	privateKeyBytes := crypto.FromECDSA(privateKey)
    // 从私钥生成公钥
	publicKey := privateKey.Public()
	publicKeyECDSA, _ := publicKey.(*ecdsa.PublicKey)
    // 从公钥生成钱包地址
	address := crypto.PubkeyToAddress(*publicKeyECDSA).Hex()[2:]
	return address, hexutil.Encode(privateKeyBytes)[2:]
}

运行代码，可在控制台看到生成的Polygon公链钱包地址：
