Coinhost is a discreet consultancy that designs, builds, and audits Bitcoin self-custody for individuals, families, treasuries, funds, and OTC desks. We have worked in this market since 2014 — long enough to have seen how most setups fail, and to know what it takes to build one that doesn't.
Self-custody rewards the people who do it correctly and punishes, eventually and completely, those who do not. The gap between the two is rarely a missing tool — it is a missing discipline.
We exist to supply that discipline. We design custody around your actual threat model, build it with you in the room, document it so it survives you, and rehearse it until it works under stress. The same craft serious custodians have used for a decade, applied one client at a time.
We keep a small book, take engagements by introduction and application, and never publish who we work with. The work speaks privately, or not at all.
Open standards, reviewed primitives, documented procedures. If a design depends on something novel or clever, it is the wrong design. Dull and durable beats elegant and fragile.
We never take custody, and we design so you can leave. Standard descriptors, exportable to Sparrow, Electrum, or Specter. A setup you cannot walk away from is a setup you do not control.
No client names, no logos, no case studies. Engagement material is handled on a need-to-know basis and returned or destroyed on completion. Discretion is part of the service.
We are a practice, not a platform. We take a limited number of engagements each quarter so that each one gets the attention custody actually requires.
If you hold real value on-chain, perhaps we should speak.
