## Features

* Lightning **send & receive** through your LNbits wallet
* **Multiple LNbits server connections** managed in one app, with a quick switcher under the home menu and per-connection identifiers and label
* **QR scanner** that auto-detects BOLT11, BOLT12, LNURL, or Lightning addresses and routes to the right flow
* **BOLT12** support: pay offers (`lno1…`) and invoices (`lni1…`), or generate your own offer for static receive
* **LNURL** support: pay, withdraw, and cryptographic auth (LUD-04)
* **Lightning addresses** (`user@host`)
* **My Contact**: share your Lightning address, BOLT12 offer, and LNURL-pay link via QR, copy, system share, or NFC. The LNURL-pay link and BOLT12 offer can be auto-generated from your LNbits server.
* **Deterministic avatars per LNbits connection** derived from your public Lightning identity, so the same connection shows the same avatar across devices and saved contacts show the same avatar as the owner's home screen
* **NFC** read and write for Lightning destinations
* Acts as a **system handler for `lightning:` deep links**. Tap a Lightning link in any app and EmberSpark opens.
* **Live transaction history**: incoming and outgoing payments surface within a few seconds, no manual refresh
* **Tap any amount** on Home or History to swap between sats and fiat. The preference persists across restarts.
* **Currency switcher** on the Receive screen, so you can enter the amount in fiat, see the sats equivalent, and create the right invoice
* **Fiat balance** display (USD / EUR / GBP / CHF / CAD / AUD / JPY) via mempool.space
* **Contacts**: save destinations you pay regularly, scan-to-add or paste, edit or delete, pick from the list on the Send-to screen
* Editable **LNbits connections** (URL, admin key, label) without losing the per-connection My-Contact entries
* **Biometric or device-PIN lock** on app launch
* API key stored in Android KeyStore via `flutter_secure_storage`
* "Allow unverified HTTPS" toggle for self-signed certificates or `.onion` LNbits servers
