    ### What's new **Lightning without your own node (experimental)** Pay a Lightning invoice without connecting a node: an atomic swap with a provider where the funds stay in your on-chain wallet (HTLC, refund path always available). Testing phase — please report anything odd. **Batch send** Pay up to 20 recipients in a single transaction: one fee instead of one per transfer. Per-row validation (dust, duplicates) and a confirmation screen listing every recipient. RBF fee bump covers the whole batch. **Addresses and UTXOs** Per-address on-chain state (never used / used and spent / holds funds), derivation path and balance for each receive and change address, plus a UTXO tab. **Faster start** Lazy block-wise address derivation: the home screen went from ~5.9 s to 1–2 s on a real device, with 20–40 addresses derived instead of 200. **Private notes per transaction** Annotate any transaction; notes stay on your device, appear in the history and are included in exports. **History export** Export the full history as CSV or JSON (copied to the clipboard; a file download in the web build), including your notes. **Clearer node diagnostics** The app recognizes the node release and explains the peering gate when no peer can connect, instead of leaving you with a silent empty list. External links now open correctly on Android. Lightning error messages are translated. ### Under the hood - 965 tests, `flutter analyze` clean - Security review follow-ups closed (challenge-response, release fail-closed, screen protection, address reuse, fee estimation) - Groundwork for PSBT (create / sign / finalise) — not user-visible yet ### Checksums ``` SHA256(btc-blake2b-wallet-v0.3.0.apk) = 9B4C5B7CFD50834C6F67B83272E59AF952F3D041BD9795E8DA9DFCFB4A23A061 ```

    ### Collegare il nodo all'app (dove trovo la stringa) 1. Installa nodo + bridge con l'installer: https://btcblake2b.org/node.html 2. La **stringa di connessione** (URI NWC) viene stampata al termine dell'installazione ed è salvata sul server: `cat ~/bridge/uri.txt` (per un altro dispositivo: `./install.sh --gen-uri`) 3. Nell'app: **Lightning → Connetti** → incolla la stringa **Esempio** (valori fittizi): `nostr+walletconnect://<pubkey-del-bridge-64-hex>?relay=wss://relay.primal.net&secret=<secret-64-hex>` ⚠️ La stringa contiene un segreto di autorizzazione: trattala come una password. ### Verifica integrità - SHA-256: `btc-blake2b-wallet-v0.2.0.apk.sha256` (in allegato) — confronta con https://btcblake2b.org/download.html - Installer nodo (v0.2.0): https://github.com/btcblake2b/control-plane/releases/tag/v0.2.0 - MIT · nessun server dell'autore · rete sperimentale, non affiliata
