Hi @jsrj78,

This issue has been resolved with my latest push. there was a problem with the way I was decoding the secret key value. Please lemme know if you still have the same issue.

My Bad I didnt read your comment carefully to understand the issue the first time.

Hi, Ibraheem Bello
I have appreciated it. The bug is fixed. But when I run my code. A source account balance is 5000000.After transfer 1000000 from source account to the destination account. I think final source account balance is 4000000 and destination account is 1000000, But I got source account balance is 5000000 and destination account is 1000000000. Can you help me?

code:

func main() {
// Change the mnemonic to something else,
// or you will get address used by others.
mnemonic := "presentx good satochit coin future media giant"
wallet := librawallet.NewWalletLibrary(mnemonic)

// create a new address
address1, childNum, err := wallet.NewAddress()
if err != nil {
	log.Fatal(err)
}

fmt.Printf("Source Account Address: %s\n", address1.ToString())

// Create account  with mnemonic and childNum
sourceAccount, err := librawallet.NewAccount(mnemonic, childNum)
if err != nil {
	log.Fatal(err)
}
// If you have your secrey key you can create account from it.
// secreyKey := "hex string of secret key here"
// sourceAccount, err := librawallet.NewAccountFromSecret(secretKey)

// Libra Client Configuration
config := goclient.LibraClientConfig{
	Host:    "ac.testnet.libra.org",
	Port:    "80",
	Network: goclient.TestNet,
}
// Instantiate LibraClient with Configuration
libraClient := goclient.NewLibraClient(config)

// Mint Coin from Test Faucet to account generated.
err = libraClient.MintWithFaucetService(sourceAccount.Address.ToString(), 5000000, true)

if err != nil {
	log.Fatal(err)
}
// Get Account State.
SourceaccState, err := libraClient.GetAccountState(sourceAccount.Address.ToString())
if err != nil {
	log.Fatal(err)
}
fmt.Printf("Source Account Balance: %s\n", SourceaccState.Balance)

// Set the current account sequence.
sourceAccount.Sequence = SourceaccState.SequenceNumber

// Amount in Micro-Libra
var amount uint64 = 1000000
destinationAddress := "f4aebe371e4176143c3409122d0adf43c0e00a6552b5b0ae9980d8981fcd0221"

// Note: Make sure the current source account sequence is set
// Get the Account State and Set the current account sequence.
// Transfer Coins from source account to destination address.
err = libraClient.TransferCoins(sourceAccount, destinationAddress, amount, 0, 10000, true)
if err != nil {
	log.Fatal(err)
}
fmt.Printf("Transfer %d coins from %x to %s", amount, sourceAccount.Address, destinationAddress)

DestinationaccState, err := libraClient.GetAccountState(destinationAddress)
if err != nil {
	log.Fatal(err)
}
fmt.Printf("Source Account Balance: %s\n", SourceaccState.Balance)

fmt.Printf("Destination Account Balance: %s\n", DestinationaccState.Balance)

}

Hi @jsrj78,

Sorry, am responding late. I have been away for some days.

I dont think you have any issue.

1. For SourceaccState, I can see you not getting the new account state after calling TransferCoins, thats why you still getting the previous balance of 5000000
2. For the destination account, pretty sure alot of other people are using that same account for test. So you neccessarily wont get the balance you are expecting because someone else may have transferred money to that account. You can generate a new destination address

Hi codemaveric,
Thanks your reply.I add GetAccountState after transferCoins.But Balance also not change.Can you help me? List my code:

func main() {
// Change the mnemonic to something else,
// or you will get address used by others.
mnemonic := "presentx goodxd satochit coinu futuree media gianto"
wallet := librawallet.NewWalletLibrary(mnemonic)

// create a new address
address1, childNum, err := wallet.NewAddress()
if err != nil {
	log.Fatal(err)
}

fmt.Printf("Source Account Address: %s\n", address1.ToString())

// Create account  with mnemonic and childNum
sourceAccount, err := librawallet.NewAccount(mnemonic, childNum)
if err != nil {
	log.Fatal(err)
}

address2, childNum2, err := wallet.NewAddress()
if err != nil {
	log.Fatal(err)
}

fmt.Printf("Destination Account Address: %s\n", address2.ToString())
destinationAccount, err := librawallet.NewAccount(mnemonic, childNum2)

// If you have your secrey key you can create account from it.
// secreyKey := "hex string of secret key here"
// sourceAccount, err := librawallet.NewAccountFromSecret(secretKey)
