I can help you with that, but I need some additional information to check your balance. Please tell me which service or platform you are referring to. For example, are you asking about your balance on a specific Lightning Network wallet, a banking platform, or something else?

To check your balance, you'll generally need to access your specific Nostr client or associated Lightning wallet. Here's a general idea of how you might do it, depending on the type of wallet you are using:

Custodial Wallets: If you are using a custodial wallet, your balance should be displayed within the wallet interface.

Non-Custodial Wallets: If you have a non-custodial wallet, you will need to manage your own private keys and connect to either your own Lightning Network node, or a trusted one, to manage and check your balance.

Some popular Lightning wallets that are used with Nostr include Alby, Mutiny Wallet, and BlueWallet.
