Why us?

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.

 

🔒 Phase 1 — Max Security (2-of-2 Multi-sig)

You hold 1 key, ResKey holds the other. Both are required to move funds. Even under duress, no one can access your Bitcoin without your confirmation.

 

🧩 Phase 2 — Smart Recovery (Single-sig)

After a delay you choose (e.g. 6 months), the vault shifts to singlesig—only your key is needed. Optionally, add a trusted backup key.

 

🆘 Phase 3 — Emergency Access (1-of-2)

As a final fallback, either key regains access—allowing recovery if you lose yours.

 

🔁 Reset Anytime

Send a transaction to restart the delay and stay in control.

 

Customizable by you!
Start with 3-of-3, 2-of-3 or any setup you whish. Add family keys. Set up inheritance rules. We tailor the vault to your life—not the other way around.

What we stand for:

Bitcoin Logo

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.
