Use cases
Five focus scenarios, each a self-contained guide to who it is for, how to set it up, and its trade-offs. None is more important than the others.
Cold wallet for high-value self-custody
An Ownbit cold wallet turns a spare phone into an air-gapped signer for high-value holdings. The offline phone holds your key and signs by QR; an online watch-only wallet monitors balances and builds transactions. No dedicated hardware to buy.
OpenTeam MultiSig for shared treasuries
Team MultiSig gives every participant equal permissions and requires several of them to approve any spend. It suits small teams, communities and shared funds where no one person should be able to move money alone, but you don't need formal roles.
OpenFamily MultiSig for shared custody
Family MultiSig lets couples and families hold crypto together, so no single lost phone or forgotten seed can put the household's savings at risk. With accident protection, the people you trust can still recover the funds if something happens to one of you.
OpenCrypto inheritance without sharing a seed
Crypto inheritance with Ownbit means your heirs can eventually access your Bitcoin and crypto without you ever sharing a seed phrase and without trusting a company to hold your keys. It uses Accident-Protection MultiSig and an on-chain recovery handover.
OpenEnterprise MultiSig for treasury governance
Enterprise MultiSig is role-based treasury governance for companies and DAOs. Unlike Team MultiSig where everyone is equal, it assigns distinct roles and weights — Owner, Signer and Security Admin — and supports whitelists and limits, managed from a web console.
