Running on a Pixel 9 with GrapheneOS
Turn any Android phone into a fully-validating Bitcoin full node with a built-in Lightning wallet. Send and receive payments validated entirely by your own node. No third parties.
No external servers. No trusted third parties. Your keys, your node, your rules.
Copy your home node's validated state over LAN. Full node at chain tip in under an hour. No days-long sync.
Pure Kotlin Electrum server on localhost. BlueWallet balances, transactions, and UTXOs all served from your own pruned node. History recovery from mempool.space fills in pruned blocks automatically. Tested and working.
UTXOracle derives BTC/USD from on-chain transaction patterns. Zero external APIs. Updates with each block.
Built-in Lightning wallet powered by LDK. Send, receive, open channels, payment history. BOLT11 and BOLT12 offers. QR codes. Seed backup and restore.
LDK-to-LND watchtower bridge protects your channels when offline. Built-in Tor (Arti) connects directly to .onion watchtowers. No external apps needed.
Fee estimates, projected blocks, transaction search. All from your own node's mempool.
Core 30, Core 29.3, or Knots 29.3. BIP 110 signaling toggle works on any compatible implementation. Switch with one tap, same chainstate.
Max Data, Low Data, Away Mode. Burst sync saves battery and data. Auto-detects WiFi/cellular and charging state. Your wallet holds peers active when you need them.
Share your validated node with nearby phones over WiFi. They scan a QR code, get the app and your chainstate. Full node in under an hour. Built, not yet tested on a second device.
W^X compliant, no root needed. Auto-start on boot, persistent mempool, foldable/landscape support. In-app updates from GitHub Releases.
No home node? Download a snapshot from the internet (3-6 hours via AssumeUTXO, on-chain only).
Or copy from a nearby phone: someone who already has the app shares their node over WiFi. Scan their QR code, download chainstate, done. No home server needed.
Everything in one app, all localhost. Full Lightning wallet with LDK.
Power modes: Max Data (continuous), Low Data (15-min burst sync), Away (60-min burst sync).
Auto-detects WiFi/cellular and charging state. External wallets hold the network active while connected.
All share the same chainstate. Switch without re-syncing. Universal BIP 110 signaling toggle.
Open source. MIT licensed. No tracking. No accounts. Just Bitcoin.
Android today. iOS is on the horizon.
