Transfer HBAR
In this section, you will learn how to transfer HBAR from your account to another on the Hedera test network.
Note: You can always check the "Code Check ✅ " section at the bottom of each page to view the entire code if you run into issues. You can also post your issue to the respective SDK channel in our Discord community here or on the GitHub repository here.
Use your new account created in the "Create an account" section and transfer 1,000 tinybars from your account to the new account. The account sending the HBAR needs to sign the transaction using its private keys to authorize the transfer. Since you are transferring from the account associated with the client, you do not need to explicitly sign the transaction as the operator account(account transferring the HBAR) signs all transactions to authorize the payment of the transaction fee.
Java
JavaScript
Go
//System.out.println("The new account balance is: " +accountBalance.hbars);
//-----------------------<enter code below>--------------------------------------
//Transfer HBAR
TransactionResponse sendHbar = new TransferTransaction()
.addHbarTransfer(myAccountId, Hbar.fromTinybars(-1000)) //Sending account
.addHbarTransfer(newAccountId, Hbar.fromTinybars(1000)) //Receiving account
.execute(client);
//console.log("The new account balance is: " +accountBalance.hbars.toTinybars() +" tinybar.");
//-----------------------<enter code below>--------------------------------------
//Create the transfer transaction
const sendHbar = await new TransferTransaction()
.addHbarTransfer(myAccountId, Hbar.fromTinybars(-1000)) //Sending account
.addHbarTransfer(newAccountId, Hbar.fromTinybars(1000)) //Receiving account
.execute(client);
//Print the balance of tinybars
//fmt.Println("The account balance for the new account is ", accountBalance.Hbars.AsTinybar())
//-----------------------<enter code below>--------------------------------------
//Transfer hbar from your testnet account to the new account
transaction := hedera.NewTransferTransaction().
AddHbarTransfer(myAccountId, hedera.HbarFrom(-1000, hedera.HbarUnits.Tinybar)).
AddHbarTransfer(newAccountId,hedera.HbarFrom(1000, hedera.HbarUnits.Tinybar))
//Submit the transaction to a Hedera network
txResponse, err := transaction.Execute(client)
if err != nil {
panic(err)
}
Note: The net value of the transfer must equal zero (the total number of HBAR sent by the sender must equal the total number of HBAR received by the recipient).
To verify the transfer transaction reached consensus by the network, you will submit a request to obtain the receipt of the transaction. The receipt status will let you know if the transaction was successful (reached consensus) or not.
Java
JavaScript
Go
System.out.println("The transfer transaction was: " +sendHbar.getReceipt(client).status);
//Verify the transaction reached consensus
const transactionReceipt = await sendHbar.getReceipt(client);
console.log("The transfer transaction from my account to the new account was: " + transactionReceipt.status.toString());
//Request the receipt of the transaction
transferReceipt, err := txResponse.GetReceipt(client)
if err != nil {
panic(err)
}
//Get the transaction consensus status
transactionStatus := transferReceipt.Status
fmt.Printf("The transaction consensus status is %v\n", transactionStatus)
You can request the cost of a query prior to submitting the query to the Hedera network. Checking an account balance is free of charge today. You can verify that by the method below.
Java
JavaScript
Go
//Request the cost of the query
Hbar queryCost = new AccountBalanceQuery()
.setAccountId(newAccountId)
.getCost(client);
System.out.println("The cost of this query is: " +queryCost);
//Request the cost of the query
const queryCost = await new AccountBalanceQuery()
.setAccountId(newAccountId)
.getCost(client);
console.log("The cost of query is: " +queryCost);
//Create the query that you want to submit
balanceQuery := hedera.NewAccountBalanceQuery().
SetAccountID(newAccountId)
//Get the cost of the query
cost, err := balanceQuery.GetCost(client)
if err != nil {
panic(err)
}
println("The account balance query cost is:", cost.String())
You will verify the account balance was updated for the new account by requesting a get account balance query. The current account balance should be the sum of the initial balance (1,000 tinybars) plus the transfer amount (1,000 tinybars) and equal to 2,000 tinybars.
Java
JavaScript
Go
//Check the new account's balance
AccountBalance accountBalanceNew = new AccountBalanceQuery()
.setAccountId(newAccountId)
.execute(client);
System.out.println("The new account balance is: " +accountBalanceNew.hbars);
//Check the new account's balance
const getNewBalance = await new AccountBalanceQuery()
.setAccountId(newAccountId)
.execute(client);
console.log("The account balance after the transfer is: " +getNewBalance.hbars.toTinybars() +" tinybar.")
//Check the new account's balance
newAccountBalancequery := hedera.NewAccountBalanceQuery().
SetAccountID(newAccountId)
//Sign with client operator private key and submit the query to a Hedera network
newAccountBalance, err := newAccountBalancequery.Execute(client)
if err != nil {
panic(err)
}
//Print the balance of tinybars
fmt.Println("The hbar account balance for this account is", newAccountBalance.Hbars.AsTinybar())
Congratulations! You have successfully transferred HBAR to another account on the Hedera Testnet! If you have followed the tutorial from the beginning, you have completed the following thus far:
⭐
- Set up your Hedera environment to submit transactions and queries.
- Created an account.
- Transferred HBAR to another account.
