Not your keys, not your coins

Hold your own keys. Without guessing.

Notarial-grade templates and guides for Bitcoin self-custody. No fluff, no affiliate links — just the exact steps to set up your wallet, back up your seed, and plan inheritance.

Open source. Air-gapped. Bitcoin only.

Verified, not invented

Every wallet step is checked against current firmware and apps. We cover Ledger, Jade, Sparrow and Green — and nothing we have not tested.

Printable and durable

A4 PDFs built to print, fill by hand, and store with your backup. The kind of document a lawyer would respect.

French and English

Each pack ships in both languages, written natively in each — not machine-translated.
