SatRyn is a self-custody Bitcoin wallet built for people who believe their keys should stay on their device. No accounts. No sign-ups. No tracking. Just Bitcoin.
SatRyn is Bitcoin-only. No altcoins, no tokens, no distractions. Just powerful tools for managing your Bitcoin with complete sovereignty.
Your private keys are encrypted with AES-256 and stored in the iOS Keychain — never on a server. You hold the keys; you control the Bitcoin.
Protect your Bitcoin with multi-signature security. Set up 2-of-3, 3-of-5, or any m-of-n configuration with hardware wallets or other apps.
No analytics. No telemetry. No third-party tracking. Connect to your own Electrum server to keep your queries completely private.
Generate your seed with provably random entropy. Draw on screen, flip coins, roll dice, or type random characters for verifiable seed generation.
Batch payments, custom fee rates, Replace-by-Fee, full coin control with UTXO selection — freeze, label, and tag your outputs.
Back up your entire wallet state encrypted with AES-256-GCM to iCloud or as a local file. Automatic daily backups keep your data safe.
