Create an account

The first account on TestNet needs to be created by calling friendbot, a helper service that will create and fund the provided account address. However, on the public network, you need an initial, funded account before you can create further accounts. Typically a wallet or exchange can create an initial account for you.

In this TestNet example, we first get an account funded from friendbot, and then demonstrate the create account operation to set up a second account.

package main

import (
	"log"

	"github.com/xdbfoundation/go/clients/frontierclient"
	"github.com/xdbfoundation/go/keypair"
	"github.com/xdbfoundation/go/network"
	"github.com/xdbfoundation/go/txnbuild"
)

func main() {
	// Generate a new randomly generated address
	pair, err := keypair.Random()
	if err != nil {
		log.Fatal(err)
	}
	log.Println("Seed 0:", pair.Seed())
	log.Println("Address 0:", pair.Address())

	// Create and fund the address on TestNet, using friendbot
	client := frontierclient.DefaultTestNetClient
	client.Fund(pair.Address())

	// Get information about the account we just created
	accountRequest := frontierclient.AccountRequest{AccountID: pair.Address()}
	hAccount0, err := client.AccountDetail(accountRequest)
	if err != nil {
		log.Fatal(err)
	}

	// Generate a second randomly generated address
	kp1, err := keypair.Random()
	if err != nil {
		log.Fatal(err)
	}
	log.Println("Seed 1:", kp1.Seed())
	log.Println("Address 1:", kp1.Address())

	// Construct the operation
	createAccountOp := txnbuild.CreateAccount{
		Destination: kp1.Address(),
		Amount:      "10",
	}

	// Construct the transaction that will carry the operation
	txParams := txnbuild.TransactionParams{
		SourceAccount:        &hAccount0,
		IncrementSequenceNum: true,
		Operations:           []txnbuild.Operation{&createAccountOp},
		Timebounds:           txnbuild.NewTimeout(300),
		BaseFee:              100,
	}
	tx, _ := txnbuild.NewTransaction(txParams)

	// Sign the transaction, and base 64 encode its XDR representation
	signedTx, _ := tx.Sign(network.TestNetworkPassphrase, pair)
	txeBase64, _ := signedTx.Base64()
	log.Println("Transaction base64: ", txeBase64)

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

	log.Println("\nTransaction response: ", resp)
}
