What is a Lightning Address?

A Lightning Address is a readable way to receive Lightning payments. In Blitz, your contact name becomes an address such as you@blitzwalletapp.com.

How it works

One address, many places to use it

It’s your contact name

Your Blitz contact name becomes your Lightning address. No long invoice to copy.

Choose USD or BTC

Customize the receiving currency. Receive as USD (USDB) to keep value stable, or as BTC to stack.

Per-account addresses

Each personal account and each NWC sub-account can have its own Lightning Address, with the same USD or BTC options.

Example

If Alex chooses “receive as USD,” any Lightning payment to alex@blitzwalletapp.com lands as USDB. Switch to BTC anytime in settings.

Where to use it

Share it wherever you post

Put it on profiles

Add it to X, Nostr, or your bio. Anyone with a Lightning wallet can pay it.

Works with compatible wallets

Other compatible wallets can pay it too. The sender needs a wallet that supports Lightning Addresses. If their wallet cannot resolve the address, share a one-time invoice QR instead.

Troubleshooting

When a Lightning payment does not arrive

Check the spelling

Addresses are exact. Confirm the contact name and domain before the sender pays.

Check the wallet

The sender must use a wallet that supports Lightning Addresses. A BOLT11 invoice QR is a useful fallback.

Check the preference

If you chose USDB, the payment may appear in your dollar balance instead of your BTC balance.
