Sending a TransferTransaction

Alice wants to send 10 symbol.xym to Bob, whose address is TBONKW-COWBZY-ZB2I5J-D3LSDB-QVBYHB-757VN3-SKPP.

Prerequisites

Method #01: Using the SDK

  1. In a new terminal, monitor which transactions involving the ticket vendor’s address are confirmed and which of them are rejected by the network.
symbol-cli monitor all --address <alice-address>
  1. Define the TransferTransaction, including Bob address as the recipient and attaching 10 symbol.xym.
// replace with recipient address
const rawAddress = 'TBONKW-COWBZY-ZB2I5J-D3LSDB-QVBYHB-757VN3-SKPP';
const recipientAddress = Address.createFromRawAddress(rawAddress);
// replace with network type
const networkType = NetworkType.TEST_NET;
// replace with symbol.xym id
const networkCurrencyMosaicId = new MosaicId('51A99028058245A8');
// replace with network currency divisibility
const networkCurrencyDivisibility = 6;

const transferTransaction = TransferTransaction.create(
    Deadline.create(),
    recipientAddress,
    [new Mosaic (networkCurrencyMosaicId,
        UInt64.fromUint(10 * Math.pow(10, networkCurrencyDivisibility)))],
    PlainMessage.create('This is a test message'),
    networkType,
    UInt64.fromUint(2000000));
// replace with recipient address
const rawAddress = 'TBONKW-COWBZY-ZB2I5J-D3LSDB-QVBYHB-757VN3-SKPP';
const recipientAddress = symbol_sdk_1.Address.createFromRawAddress(rawAddress);
// replace with network type
const networkType = symbol_sdk_1.NetworkType.TEST_NET;
// replace with symbol.xym id
const networkCurrencyMosaicId = new symbol_sdk_1.MosaicId('51A99028058245A8');
// replace with network currency divisibility
const networkCurrencyDivisibility = 6;
const transferTransaction = symbol_sdk_1.TransferTransaction.create(symbol_sdk_1.Deadline.create(), recipientAddress, [new symbol_sdk_1.Mosaic(networkCurrencyMosaicId, symbol_sdk_1.UInt64.fromUint(10 * Math.pow(10, networkCurrencyDivisibility)))], symbol_sdk_1.PlainMessage.create('This is a test message'), networkType, symbol_sdk_1.UInt64.fromUint(2000000));
        // replace with node endpoint
        try (final RepositoryFactory repositoryFactory = new RepositoryFactoryVertxImpl(
                "http://api-01.us-west-1.symboldev.network:3000/")) {
            // replace with recipient address
            final String rawAddress = "TBONKW-COWBZY-ZB2I5J-D3LSDB-QVBYHB-757VN3-SKPP";
            final UnresolvedAddress recipientAddress = Address.createFromRawAddress(rawAddress);
            final NetworkType networkType = repositoryFactory.getNetworkType().toFuture().get();
            // replace with symbol.xym id
            final MosaicId networkCurrencyMosaicId = new MosaicId("51A99028058245A8");
            // replace with network currency divisibility
            final Integer networkCurrencyDivisibility = 6;
            // replace with relative amount of symbol.xym to send
            final BigInteger amount = BigInteger.valueOf(10);

            final Mosaic mosaic = new Mosaic(networkCurrencyMosaicId,
                    amount.multiply(BigInteger.valueOf(10).pow(networkCurrencyDivisibility)));
            final TransferTransaction transferTransaction = TransferTransactionFactory
                    .create(
                            networkType,
                            recipientAddress,
                            Collections.singletonList(mosaic),
                            PlainMessage.create("This is a test message"))
                    .maxFee(BigInteger.valueOf(2000000)).build();

As you may have noticed, transfer transactions require an array of mosaics as a parameter. This permits sending transfer transactions with multiple mosaics at the same time.

If you own more than one mosaic, you can send them together in the same transaction:

    [new Mosaic( new MosaicId('7CDF3B117A3C40CC'), UInt64.fromUint(1000)),
        new Mosaic ( new MosaicId('51A99028058245A8'), UInt64.fromUint(10 * Math.pow(10, 6)))],
[new symbol_sdk_1.Mosaic(new symbol_sdk_1.MosaicId('7CDF3B117A3C40CC'), symbol_sdk_1.UInt64.fromUint(1000)),
    new symbol_sdk_1.Mosaic(new symbol_sdk_1.MosaicId('51A99028058245A8'), symbol_sdk_1.UInt64.fromUint(10 * Math.pow(10, 6)))], 
                            Arrays.asList(new Mosaic(new MosaicId("7CDF3B117A3C40CC"),
                                            BigInteger.valueOf(1000)),
                                    new Mosaic(new MosaicId("51A99028058245A8"),
                                            BigInteger.valueOf(10000000))),

Note

Symbol works with absolute amounts. To get an absolute amount, multiply the number of assets you want to send by 10divisibility. For example, if the mosaic has divisibility 2, to send 10 units (relative) you should define 1000 (absolute) instead.

  1. Sign the transaction with Alice’s account.

Note

Include the first block generation hash to make the transaction only valid for your network. Open nodeUrl + '/block/1' in a new browser tab and copy the meta.generationHash value.

// replace with sender private key
const privateKey = '1111111111111111111111111111111111111111111111111111111111111111';
const account = Account.createFromPrivateKey(privateKey, networkType);
// replace with meta.generationHash (nodeUrl + '/block/1')
const networkGenerationHash = '44D2225B8932C9A96DCB13508CBCDFFA9A9663BFBA2354FEEC8FCFCB7E19846C';
const signedTransaction = account.sign(transferTransaction, networkGenerationHash);
// replace with sender private key
const privateKey = '1111111111111111111111111111111111111111111111111111111111111111';
const account = symbol_sdk_1.Account.createFromPrivateKey(privateKey, networkType);
// replace with meta.generationHash (nodeUrl + '/block/1')
const networkGenerationHash = '44D2225B8932C9A96DCB13508CBCDFFA9A9663BFBA2354FEEC8FCFCB7E19846C';
const signedTransaction = account.sign(transferTransaction, networkGenerationHash);
            // replace with private key
            final String privateKey = "1111111111111111111111111111111111111111111111111111111111111111";
            // replace with network generation hash
            final String generationHash = repositoryFactory.getGenerationHash().toFuture().get();

            final Account account = Account
                    .createFromPrivateKey(privateKey, networkType);
            final SignedTransaction signedTransaction = account
                    .sign(transferTransaction, generationHash);
  1. Once signed, announce the transaction to the network.
// replace with node endpoint
const nodeUrl = 'http://api-01.us-west-1.symboldev.network:3000';
const repositoryFactory = new RepositoryFactoryHttp(nodeUrl);
const transactionHttp = repositoryFactory.createTransactionRepository();

transactionHttp
    .announce(signedTransaction)
    .subscribe((x) => console.log(x), (err) => console.error(err));
// replace with node endpoint
const nodeUrl = 'http://api-2-01.us-west-1.symboldev.network:3000';
const repositoryFactory = new symbol_sdk_1.RepositoryFactoryHttp(nodeUrl);
const transactionHttp = repositoryFactory.createTransactionRepository();
transactionHttp
    .announce(signedTransaction)
    .subscribe((x) => console.log(x), (err) => console.error(err));
            final TransactionRepository transactionRepository = repositoryFactory
                    .createTransactionRepository();
            transactionRepository.announce(signedTransaction).toFuture().get();
        }

5. Open the terminal where you are monitoring the transaction’s status. The transaction should appear as confirmed after ±15 seconds and the amount defined gets transferred from the sender’s account to the recipient’s account. If the terminal raises an error, check the error code meaning here.

Method #02: Using the CLI

 symbol-cli transaction transfer --recipient-address TBONKW-COWBZY-ZB2I5J-D3LSDB-QVBYHB-757VN3-SKPP --mosaics "@symbol.xym::10000000" --message "This is a test message" --sync
