Paying lumens from root account to a keypair.

dzham

you need to use a createAccount operation, https://www.stellar.org/developers/guides/concepts/list-of-operations.html#create-account

Can you please show me an example?

dzham

	operation = StellarSdk.Operation.createAccount({
		destination: destInfo.id,
		startingBalance: '20'
	});

Should this operation be wrapped in a transaction? Also, I know, that the source is optional. However, the explanation on the page is not clear; "Defaults to the transaction's source account.". For now, I am using the root account because, I want to fund this account to begin with.

This is my approach:

var transaction = new StellarSdk.TransactionBuilder(sourceAccount)
  .addOperation(StellarSdk.Operation.createAccount({
  destination: destinationId,
  startingBalance: xferAmount,
  source : sourceKeys.publicKey()
}))
  .addMemo(StellarSdk.Memo.text('Test Transaction'))
  .build();
  
transaction.sign(sourceKeys);
server.submitTransaction(transaction);

dzham

Your approach looks good.

"source" in an operation is only needed if it's not the same account as the one you initialize your TransactionBuilder with.

ok, this is what I get:

/home/champ/node_modules/stellar-base/lib/transaction_builder.js:143
                var sequenceNumber = new BigNumber(this.source.sequenceNumber()).add(1);
                                                               ^

TypeError: this.source.sequenceNumber is not a function

    at startup (node.js:136:18)
    at node.js:966:3

This is what I am using:

StellarSdk.Network.use(new StellarSdk.Network(NETWORK_PASSPHRASE));
var opts = new StellarSdk.Config.setAllowHttp(true);
var server = new StellarSdk.Server(HORIZON_ENDPOINT, opts);
var sourceKeys = StellarSdk.Keypair.fromSecret(fromWallet);
var destinationId = toWallet;

var transaction = new StellarSdk.TransactionBuilder(sourceKeys.publicKey())
  .addOperation(StellarSdk.Operation.createAccount({
    destination: destinationId,
    startingBalance: xferAmount,
    source : sourceKeys.publicKey()
  }))
  .addMemo(StellarSdk.Memo.text('Test Transaction'))
  .build();
  
transaction.sign(sourceKeys);
server.submitTransaction(transaction);

dzham

You need to put it inside

server.loadAccount(sourceKeys.publicKey())
.then(function(sourceAccount) {
}

chainhead

Yay! Got it working now. Thanks, dzham ?

Here is my final attempt.

var sourceKeys = StellarSdk.Keypair.fromSecret(fromWallet);
var destinationId = toWallet;

server.loadAccount(sourceKeys.publicKey())
  .then(function(sourceAccount) {
    var txn = new StellarSdk.TransactionBuilder(sourceAccount)
                .addOperation(StellarSdk.Operation.createAccount({
                    destination: destinationId,
                    startingBalance: xferAmount
                  }
                  )
                )
                .addMemo(StellarSdk.Memo.text('Test Transaction')
                )
                .build();
                
    txn.sign(sourceKeys);
    return server.submitTransaction(txn);
    })
  .then(function(result) {
    console.log('Success! Results:', result);
  })
  .catch(function(error) {
    console.error('Something went wrong!', error);
  });

getting error:

txn.sign(sourceKeys); return undefined.

Hard to say when result_codes isn't visible

I am trying send fund from root account,

helloravi

sohan Did you figure it out?

helloravi

All those who are looking to solve this issue. You have to check the network phrase from http://localhost:8000 and use the right network phrase.

tx_bad_seq is coming for me while sending from root account to new keypair. any idea about it?

Vishwas1 This is my guess as I don't know the protocol in depth but "bad sequence" probably means that the Sequence Number you sent in your transaction is not what Horizon expected.
If you check your account (e.g. https://horizon.stellar.org/accounts/GAREELUB43IRHWEASCFBLKHURCGMHE5IF6XSE7EXDLACYHGRHM43RFOX ) you can see a value like
"sequence": "27707856228712522",
If you submit a transaction with this number incremented +1, you should be good.
