How It Works
At ResKey, we protect your Bitcoin using Liana—open-source wallet software that powers a smart, time-based multisig vault tailored to your needs.
This is how a basic setup looks like:
🔐 Phase 1 — Maximum Security (2-of-2)
You hold one key, ResKey holds the other.
Both are required to move funds — ResKey can never act alone.
Your Bitcoin stays locked without your approval. Nobody can force you to move funds.
🧩 Phase 2 — Smart Recovery and Inheritance (2-of-3)
After a set delay, control shifts to a 2-of-3 setup:
You hold two keys (hardware + software), ResKey holds a backup.
Any two can spend — you stay in full control, with built-in recovery and inheritance options by giving the software key to a heir.
🆘 Phase 3 — Inheritance and Unilateral Exit (1-of-2)
If ResKey is unavailable, you can spend with just one key.
Stay fully independent, forever.
Your software key can also serve as an inheritance key.
🛠️ Optional: Third-Party Backup
Add a backup key held by someone you trust.
ResKey still can’t act alone, but can help recover your funds together with your trusted party if all your keys are lost.
🔁 Reset Anytime
Send a transaction to restart the delay and stay in control.
Customizable by you!
We tailor the vault to your life—not the other way around.
The only restriction is that there can never be a situation where reskey can move funds alone.
What we stand for:
Bitcoin only
We are Bitcoin-only because our collaborative custody model relies on the unique security that only Bitcoin offers. Multisig, inheritance, and sovereignty work best when built on the most robust and decentralized protocol.
Open Source
We only use open source software and hardware because trust should be earned through transparency—not taken for granted. With open source, every line of code and every device can be verified, not just believed.
Trustless
We build everything to be trustless—because real security means you don’t have to trust us. Our setup ensures you stay in full control of your Bitcoin at all times, with us only stepping in when you truly need it.
Secure
Security is at the core of everything we do. With time-tested multisig, offline key storage, and no single point of failure, your Bitcoin stays protected—no matter what happens.
Adaptive
Our solutions are adaptive because every Bitcoiner’s needs are different. Whether it’s inheritance planning, theft protection, or key loss recovery—your setup evolves with you.
