交易所钱包开发-------USDT开发

一、基于ERC20的USDT开发（go开发）

1、地址生成

    func generateAddr() {

        privateKey, err := crypto.GenerateKey()

        if err != nil {

            log.Fatal(err)

        }

        privateKeyBytes := crypto.FromECDSA(privateKey)

        privateKeyStr := hexutil.Encode(privateKeyBytes)[2:]

        log.Println("-String--private key ---", privateKeyStr)

        publicKey := privateKey.Public()

        publicKeyECDSA, ok := publicKey.(*ecdsa.PublicKey)

        if !ok {

            log.Fatal("error casting public key to ECDSA")

        }

        publicKeyBytes := crypto.FromECDSAPub(publicKeyECDSA)

        publicKeyStr := hexutil.Encode(publicKeyBytes)[4:]

        log.Println("-String--public key ---", publicKeyStr)

        address := crypto.PubkeyToAddress(*publicKeyECDSA).Hex()

        return privateKeyStr, publicKeyStr, address

    }

二、基于OMNI协议的USDT开发（nodejs开发）

1、地址生成

let randomBytes = require('randombytes');

let BigInteger = require('bigi');

let ecurve = require('ecurve');

let crypto = require('crypto');

let cs = require('coinstring');

function generateAddress() {

    let secp256k1 = ecurve.getCurveByName('secp256k1')

    let randombytes = randomBytes(32).toString('hex')

    let privateKey = Buffer.from(randombytes, 'hex')

    let ecparams = ecurve.getCurveByName('secp256k1')

    let curvePt = ecparams.G.multiply(BigInteger.fromBuffer(privateKey))

    let x = curvePt.affineX.toBuffer(32)

    let y = curvePt.affineY.toBuffer(32)

    let publicKey = Buffer.concat([Buffer.from([0x04]), x, y])

    //compressed

    publicKey = curvePt.getEncoded(true) //true forces compressed public key

    console.log("压缩公钥 :" + publicKey.toString('hex'))

    let sha = crypto.createHash('sha256').update(publicKey).digest()

    let pubkeyHash = crypto.createHash('rmd160').update(sha).digest()

    let address = cs.encode(pubkeyHash, 0x0)

    // address of compressed public key

    console.log("压缩地址：" + address) //<-- 0x0 is for public addresses

    //校验和Base58编码

    // let private_key2 = cs.encode(privateKey, 0x80) // private_key2 have some problem

    // console.log(private_key2) //<--- 0x80 is for private addresses

    let private_key = cs.encode(Buffer.concat([privateKey, new Buffer([0x01])]), 0x80)

    console.log("压缩私钥：" + private_key) // <-- compressed private address

    return [address, publicKey.toString('hex'), private_key]

}

module.exports = {

    generateAddress

}
