A comprehensive Bitcoin wallet with no compromises. Every tool you need for true self-custody, built with privacy and security at every layer.
Private keys encrypted with AES-256 and stored in the iOS Keychain — never on a server. Supports 11 wallet types including HD wallets from 12 or 24-word seed phrases, extended key imports, output descriptors, Electrum seeds, and watch-only wallets. You hold the keys; you control the Bitcoin.
Multi-signature security for your most important Bitcoin. Configure 2-of-3, 3-of-5, or any m-of-n setup. Add cosigners from hardware wallets like Coldcard, Trezor, or Ledger. Create, sign, and finalize PSBTs for collaborative custody.
Full support for all four Bitcoin address types simultaneously. Taproot (bc1p) for the latest protocol features, Native SegWit (bc1q) for optimal fees, Wrapped SegWit (3) for broad compatibility, and Legacy (1) for maximum interoperability.
Batch payments to multiple recipients in a single transaction. Mempool-based fee estimates, custom fee rate input, and Replace-by-Fee support. Full coin control — freeze, label, and tag UTXOs. QR code scanning, address validation, and similarity detection to prevent mistakes.
Inspect every detail of your transactions — inputs, outputs, fees, confirmations, block height, and RBF status. Add notes and labels to keep your history organized. Export any transaction as a PDF for your records or reporting.
Back up your entire wallet state encrypted with AES-256-GCM to iCloud or as a local file. Automatic daily backups run in the background to keep your data safe. Restore on any device with your backup password — no seed phrase re-entry needed.
Generate your seed with provably random entropy you can verify. Draw on screen, flip coins, roll dice, or type random characters. Your physical randomness is mixed with device entropy using HKDF-SHA256 for a cryptographically secure seed every time.
PIN protection with 4 to 32 digits and progressive lockout after failed attempts. Face ID and Touch ID for fast, biometric authentication. Screenshot blocking on sensitive screens, configurable auto-lock, and private keys decrypted only during signing then cleared from memory.
No analytics. No telemetry. No third-party tracking. SatRyn never phones home. Connect to your own Electrum server to keep your balance queries, transaction history, and address lookups completely private. Your financial data stays yours.
Bitcoin-only. No altcoins, no tokens, no distractions. Full BIP support: BIP39, BIP32, BIP44, BIP49, BIP84, BIP86, BIP48, BIP125, and BIP174. Native Taproot from day one. Built on bitcoinjs-lib with the secp256k1 elliptic curve library.
Save Bitcoin addresses with names and tags for easy identification. View transaction history per contact to track payments over time. Quick-access recent recipients so you can send to frequent contacts in seconds.
Display your balance in Bitcoin, millibitcoin, bits, or satoshis. Live fiat conversion in over 50 currencies so you always know what your Bitcoin is worth in your local money. Switch denominations instantly from anywhere in the app.
Choose the look that fits your style. Light for daytime use, Dim for reduced eye strain, and Midnight — a true black OLED theme that saves battery and looks stunning on modern displays. Every screen is designed for all three.
Fully open source with no backdoors and no hidden code. Inspect every line, verify every function, and build from source yourself. Don't Trust, Verify. The way Bitcoin software should be.
