Fortis Wallet A non-custodial mobile wallet for Bitcoin XBT and Bitcoin BTC, locked with your fingerprint. Your recovery phrase is generated on your phone, encrypted there, and never leaves it. Locked with your fingerprint (or face, or device PIN): the key that opens the app is held in your phone's secure hardware (StrongBox or the TEE) and is released only when you unlock - one unlock opens every wallet. Locks itself a minute after you leave it, and clears your keys from memory; swaps carry on in the background. Asks again before it shows your recovery phrase or sends coins. Your recovery phrase is encrypted on the phone (Argon2id + XChaCha20-Poly1305) and never sent anywhere. Every screen is kept out of screenshots, screen recordings and the recent-apps view. Swap BTC <-> XBT with another person: atomic and non-custodial (on-chain HTLCs, nobody holds your coins in the middle). Post an offer, take one from the list, or swap privately by code; it runs in the background, a cancelled match releases your coins back within minutes, and "Find my swaps" recovers them from your phrase on a new phone. 12- or 24-word BIP-39 phrase, BIP-84 native SegWit, optional passphrase. Up to 10 named wallets, any mix of XBT and BTC, from the one phrase. Send and receive with QR codes, a built-in camera scanner, or paste. Fee presets or a custom sat/vB rate; "take the fees out of this amount"; sweep a whole balance. History with a tap-through to a block explorer; approximate value in USD, EUR or 28 other currencies (Settings -> Currency). Connect a hardware wallet (Keystone, Passport, SeedSigner, Jade and others) as a view-only BTC wallet by scanning its account QR. Cross-chain replay protection: SIGHASH_UNIFIED on every XBT send (automatic), plus an optional oversized OP_RETURN on BTC sends. Extra entropy from your hands: shake the phone, scribble on screen, or CPU-timing jitter, folded into the seed. In 75 languages, picked in Settings or following your phone. No analytics, no ads, no third-party SDKs; the backend only ever sees public addresses and finished signed transactions - no account, no sign-up. Standard, portable keys - restore the same phrase in any BIP-84 wallet. Open source (MIT). No Google Play Services.
