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.
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())
}
}

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