มาสร้าง Stellar Account ด้วย Go SDK กัน

ลองสร้าง Stellar Account และรับ 1000 XLM จาก Testnet ดู ด้วย Go SDK

package main

import (
    "log"

    "github.com/stellar/go/clients/horizonclient"
    "github.com/stellar/go/keypair"
    "github.com/stellar/go/network"
    "github.com/stellar/go/txnbuild"
)

func main() {
    pair, _ := keypair.Parse("secret key")
    addr := pair.Address()
    client := horizonclient.DefaultTestNetClient
    accountRequest := horizonclient.AccountRequest{AccountID: addr}
    account1, err := client.AccountDetail(accountRequest)
    if err != nil {
        log.Fatalln(err)
    }
    des, _ := keypair.Random()

    createAccountOp := txnbuild.CreateAccount{
        Destination: des.Address(),
        Amount:      "1000",
    }
    txParams := txnbuild.TransactionParams{
        SourceAccount:        &account1,
        IncrementSequenceNum: true,
        Operations:           []txnbuild.Operation{&createAccountOp},
        BaseFee:              txnbuild.MinBaseFee,
        Timebounds:           txnbuild.NewTimeout(300),
    }
    tx, _ := txnbuild.NewTransaction(txParams)

    signedTx, err := tx.Sign(network.TestNetworkPassphrase, pair.(*keypair.Full))
    if err != nil {
        log.Fatalln(err)
    }
    txeBase64, err := signedTx.Base64()
    if err != nil {
        log.Fatalln(err)
    }
    log.Println("Transaction base64: ", txeBase64)

    resp, err := client.SubmitTransactionXDR(txeBase64)
    if err != nil {
        hError := err.(*horizonclient.Error)
        log.Fatal("Error submitting transaction:", hError.Problem)
    }

    log.Println("Transaction response: ", resp)
}
