We are on a mission to give every Bitcoiner complete sovereignty over their wealth — with no compromises on security, privacy, or usability.
SatRyn exists because we believe that holding your own keys is not just a technical preference — it is a fundamental right. Every person should be able to send, receive, and store Bitcoin without trusting a third party with their wealth.
Our mission is to give people complete sovereignty over their Bitcoin with no compromises on security or privacy. We build tools that are powerful enough for experts yet accessible enough for everyone.
No venture capital. No token sales. No data monetization. Just open-source software that puts you in control.
Every decision we make is guided by these core principles. They are not marketing words — they are the standards we hold ourselves to in every line of code.
Your keys, your coins. No intermediaries, no custodians, no permission needed. SatRyn ensures you — and only you — control your Bitcoin.
No analytics, no tracking, no telemetry. We do not collect your data because we do not want your data. Connect your own node for complete privacy.
Every line of code is public and verifiable. Don't trust — verify. Our entire codebase is available on GitHub for anyone to audit.
No altcoins, no distractions, pure Bitcoin focus. We dedicate 100% of our effort to building the best Bitcoin wallet possible.
Defense-in-depth at every layer. From AES-256-GCM encryption to iOS Keychain storage, security is not an afterthought — it is the foundation.
Powerful tools made accessible. Advanced features like coin control, multisig, and custom fees are available to everyone, not just power users.
SatRyn is built on bitcoinjs-lib with the secp256k1 elliptic curve library — the same battle-tested cryptographic foundations trusted across the Bitcoin ecosystem.
We implement a comprehensive set of Bitcoin Improvement Proposals: BIP39 and BIP32 for hierarchical deterministic wallets, BIP44/49/84/86 for all address formats including native Taproot, BIP48 for multisig derivation, BIP125 for Replace-by-Fee, and BIP174 for Partially Signed Bitcoin Transactions.
Every standard is implemented faithfully, tested rigorously, and open for anyone to audit. No shortcuts, no proprietary protocols, no black boxes.
