Your keys, your Bitcoin. Self-custody wallet with multisig vaults, coin control, Taproot support, and real-time sync. No tracking. No third parties.
SatRyn is a secure, self-custody Bitcoin wallet for iPhone that keeps your private keys on your device, not on a server. Whether you're storing your first satoshis or managing a multi-signature Bitcoin vault, SatRyn gives you full control with no sign-ups, no accounts, and no tracking.
SECURE BITCOIN WALLET — SELF-CUSTODY
Your Bitcoin, your keys. SatRyn encrypts private keys with AES-256 and stores them in the iOS Keychain. This Bitcoin wallet supports 11 wallet types: HD wallets from 12 or 24-word seed phrases, extended key imports, output descriptors, Electrum seeds, imported keys, and watch-only Bitcoin wallets.
BITCOIN MULTISIG VAULTS
Protect your Bitcoin with multi-signature security. Set up 2-of-3, 3-of-5, or any m-of-n Bitcoin vault. Add cosigners from hardware wallets or other Bitcoin apps. Create, sign, and coordinate PSBTs — the standard for secure Bitcoin signing across devices.
ALL BITCOIN ADDRESS FORMATS
Taproot (bc1p), Native SegWit (bc1q), Wrapped SegWit (3), and Legacy (1). Each Bitcoin wallet generates all four formats — always have the right address for any transaction.
SEND & RECEIVE BITCOIN
Send Bitcoin to one address or batch multiple payments in one transaction. Real-time mempool fee estimates or custom sat/vB rate. Bump stuck transactions with Replace-by-Fee. Full coin control: select, freeze, label, and tag UTXOs. Built-in QR scanner with address validation and poisoning detection.
BITCOIN TRANSACTION DETAILS
Inspect every Bitcoin transaction: inputs, outputs, fees, confirmations, block height, and RBF status. Add notes and labels. Export history as PDF. Full transparency for every sat.
ENCRYPTED BITCOIN BACKUP
Back up your Bitcoin wallet — seeds, settings, contacts, labels — encrypted with AES-256-GCM to iCloud or local file. Automatic daily backups ensure you never lose access. Restore on any device with your password.
TRUE RANDOM SEED GENERATION
Generate your Bitcoin seed phrase with provably random entropy. Draw on screen, flip coins, roll dice, or type random characters — mixed with cryptographic RNG using HKDF-SHA256 for verifiable key generation.
BITCOIN SECURITY
- PIN protection (4-32 digits) with progressive lockout
- Face ID and Touch ID authentication
- Screenshot blocking on sensitive screens
- Auto-lock with configurable timeout
- Keys decrypted only during signing, then cleared from memory
PRIVATE BITCOIN WALLET — NO TRACKING
Zero analytics. Zero telemetry. Connect to your own Electrum server for fully private Bitcoin queries. SatRyn never phones home.

I’m not super technical, so I wanted something that didn’t overwhelm me. The main screen shows balance and recent activity without too many charts or extra stuff; Checking past transactions and details like confirmations is pretty straightforward.
Easy setup on my phone
Nicholson Nunez
I downloaded it late at night to move some BTC off an exchange. The setup was straightforward and I liked that it walked me through backing up the recovery phrase without rushing. Took me maybe five minutes and I felt cọmfortable sending my first small transfer right away.
Developer Response
Really appreciate the review, Nicholson! That smooth onboarding experience is something we put a lot of thought into — security should feel natural, not intimidating. If there’s anything that kept it from being a full 5 stars, we’d love to hear about it. Always improving!

Use with your risks. I get an important lesson. Do not put much coin on an unpopular wallet. Btw I can confirm the seed is saved properly as well as other wallet. But only this one get drained.
