INDEPENDENCE IS A DESIGN DECISION.
Your bitcoin. Your authority.
We design custody that puts you in control —
and keeps you there when life changes.
Separate keys.
Shared authority.
THE OPERATING PRINCIPLE
We help you hold your own bitcoin. With the right architecture, a clear recovery plan, and the confidence to use both.
WHY COINHOSTIndependent expertise at every stage.
Choose the work you need. Keep control
of the system we build.
THE FOUNDATION / BUILT AROUND YOU
A custody arrangement designed around what you hold, who can act, and which failures it needs to survive. From a first hardware wallet to a distributed multisig setup.
ASSUMPTIONS → EVIDENCE
Understand the weak points in your existing setup. Review signers, locations, and recovery paths, then put the plan through a controlled drill.
BUILT TO OUTLAST THE UNEXPECTED
Make a plan that the right people can follow. Inheritance, succession, written instructions, and practical training — rehearsed while you can refine it.
Custody should fit the life around it.
Explore the 2-of-3 beta and our vision
for a wider range of multisignature models.
Three keys are distributed.
Any two are needed to sign.
A signing key on your phone. Your first point of control.
A separate device and a separate signing key.
A backup path. Never enough to move funds on its own.
Your mobile and hardware keys authorize an everyday transaction. Coinhost is not required to sign.
SCENARIO / 01Your hardware key and the Coinhost recovery key provide another path, subject to the recovery process and cooling period.
SCENARIO / 02Keep your descriptor and access to both of your keys. Rehearse signing with compatible tools before you need an independent exit.
SCENARIO / 03CONCEPTUAL SIGNING MODEL / NOT A LIVE WALLET SECURITY DETAILS ↗
THE NEXT MODEL / 3-OF-5
Five independent keys. Any three can sign.
A model for distributing authority across more people, devices, or locations.
3 of 5 keys available. Any three can authorize a transaction.
This illustrates the 3-of-5 principle. Signer roles and recovery details will be defined as the model develops.
Understand your threat model, your priorities, and the people who need access.
Map the signers, locations, and recovery paths. Make the trade-offs explicit.
Set up the devices, distribute the keys, and verify the custody arrangement together.
Practice signing, loss, and recovery. Leave with a system you can operate.
A custody plan is only useful if you know how to use it when something changes.
