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

• Finish the getting started section.
• Have one account with xpx currency.
• Have sent mosaics to another account.
• Text editor or IDE.
• XPX-Chain-SDK or XPX-Chain-CLI.

Getting into some code

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

Golang

TypeScript

JavaScript

Java

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())
    }
}

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

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