U App XMR

Monero, private by default.

U App XMR is the open-source companion for the U App. Reveal your 25-word Monero phrase in the U App, scan it here, and this wallet holds, syncs, and sends your XMR entirely on-device.

Keys never leave

Scan the phrase QR from the U App; the wallet file is sealed with AES-256-GCM under your device Keystore.

Full Monero wallet

Balances, history, and sends with real ring signatures via the sandboxed wallet2 engine, round-robined public nodes.

Verify on import

An independent in-app implementation of the derivation checks that the restored address matches your U App address.

How it works

  1. Install the U App and the U App XMR companion.
  2. In the U App: Profile > Security > Reveal Monero phrase (25 words).
  3. In U App XMR: Scan QR (or paste). The app derives the address and checks it matches.
  4. Import. The companion syncs and handles everything XMR from then on.
Open source: this app is licensed under GPL-3.0 and its full source is at github.com/UdotCASH/u-app-xmr. The U App itself stays GPL-free; the two share keys only through your 25-word phrase. Developer build: install at your own risk.
