Getting the amount of XPX sent to an account

This guide will help you check the amount of XPX you have sent to any account.

Prerequisites

Getting into some code

In this example, we are going to check how many assets of a certain type have we sent to an account.

conf, err := sdk.NewConfig(context.Background(), []string{"http://bctestnet1.brimstone.xpxsirius.io:3000"})
if err != nil {
    panic(err)
}

// Use the default http client
client := sdk.NewClient(nil, conf)

address, err := sdk.NewAddressFromPublicKey("...", client.NetworkType())
if err != nil {
    panic(err)
}

accountInfo, err := client.Account.GetAccountInfo(context.Background(), address)
if err != nil {
    panic(err)
}

for _, mosaic := range accountInfo.Mosaics {
    if mosaic.AssetId == sdk.XpxNamespaceId {
      fmt.Println(mosaic.String())
    }
}

import { mergeMap, map, filter, toArray } from 'rxjs/operators';

const accountHttp = new AccountHttp('http://bctestnet1.brimstone.xpxsirius.io:3000');

const originPublicKey = '7D08373CFFE4154E129E04F0827E5F3D6907587E348757B0F87D2F839BF88246';
const originAccount = PublicAccount.createFromPublicKey(originPublicKey, NetworkType.TEST_NET);

const recipientAddress = 'VDG4WG-FS7EQJ-KFQKXM-4IUCQG-PXUW5H-DJVIJB-OXJG';
const address = Address.createFromRawAddress(recipientAddress);

accountHttp

        map((_) => _.mosaics[0].amount.compact() / Math.pow(10, NetworkCurrencyMosaic.DIVISIBILITY)), // Map only amount in xpx
        toArray(), // Add all mosaics amounts into one array
        map((_) => _.reduce((a, b) => a + b, 0))
    )

const recipientAddress = 'VDG4WG-FS7EQJ-KFQKXM-4IUCQG-PXUW5H-DJVIJB-OXJG';

    );
        // Replace with public key
        final String originPublicKey = "<public_key>";

        // Replace with recipient address
        final String recipientAddress = "VB2RPH-EMTFMB-KELX2Y-Q3MZTD-RV7DQG-UZEADV-CYKC";

        // Replace with public key

        final Address address = Address.createFromRawAddress(recipientAddress);

        final AccountHttp accountHttp = new AccountHttp("http://bctestnet1.brimstone.xpxsirius.io:3000");

        final BigInteger total = accountHttp.outgoingTransactions(originAccount)
                .flatMapIterable(tx -> tx) // Transform transaction array to single transactions to process them
                .filter(tx -> tx.getType().equals(TransactionType.TRANSFER)) // Filter transfer transactions
                .map(tx -> (TransferTransaction) tx) // Map transaction as transfer transaction
                .filter(tx -> tx.getRecipient().equals(address)) // Filter transactions from to account
                .filter(tx -> tx.getMosaics().size() == 1 && tx.getMosaics().get(0).getId().equals(NetworkCurrencyMosaic.ID)) // Filter xpx transactions
                .map(tx -> tx.getMosaics().get(0).getAmount().divide(BigDecimal.valueOf(Math.pow(10, NetworkCurrencyMosaic.DIVISIBILITY)).toBigInteger())) // Map only amount in xpx
                .toList() // Add all mosaics amounts into one array
                .map(amounts -> amounts.stream().reduce(BigInteger.ZERO, BigInteger::add))
                .toFuture()
                .get();

        System.out.println("Total xpx send to account " + address.pretty() + " is: " + total.toString());

If you want to check another mosaic different than the native currency, change mosaicId for the target mosaic.
