The platform
Custody policy you can hand to someone else.
Sentinel turns how you hold Bitcoin into a written policy — one a lawyer, an executor or an auditor can read and act on. You describe the arrangement; the software checks it and produces the document.
What you get
- A governance brief
- One document describing the policy in plain language, for the person who has to act on it.
- A deterministic check
- Every policy is verified by a Miniscript proof engine — four gates, a pass or a fail, no judgement call.
- A readiness score
- Five pillars, so you can see which part of the arrangement is weakest before someone else does.
Who it is for
Fiduciary consultants who have to show their work, and holders whose arrangement has to survive them. If a custody question ends with someone else needing to understand what you set up, that document is the thing Sentinel makes.
