01The 2-of-3 model

Three keys. No single point of failure.

Any two of three keys can move funds, so losing one key never loses your Bitcoin, and no single party can ever act alone.

KEY 01

Your first hardware key

A Trezor with its own steel backup plate, delivered to your door. You set it up yourself, we guide every step.

KEY 02

Your second hardware key

A Ledger with its own backup plate, in the same delivery. Set up by you, held by you.

KEY 03

SimplB recovery key

Held on an air-gapped Coldcard for recovery and inheritance. We can never move funds alone.

02What you get

You generate your own keys with us guiding every step, we never see or touch them, then store all four items, two wallets and two plates, in four separate secure locations we plan with you

The Vault attracts management fees, confirmed with you in your consultation before anything is set up. Hardware is included in your setup and supplied in limited quantities: we do five Vault setups a month, by consultation only.
