Bitcoin Keeper
Open-source Bitcoin vault with multisig, hardware wallet support, and inheritance planning for long-term holders.
Why We Recommend Bitcoin Keeper
Bitcoin Keeper is a fully non-custodial, open-source wallet where users maintain complete control of their private keys. The company never has access to user funds and cannot sign or authorize transactions on behalf of users.
The application code is publicly available on GitHub (bithyve/bitcoin-keeper), allowing independent security review by the community. Bitcoin Keeper provides signed checksums and detached GPG signatures for APK verification, enabling users to confirm they are running authentic, unmodified software. WalletScrutiny has included Bitcoin Keeper in their build verification efforts, indicating attention to transparency.
The wallet supports connecting to your own Bitcoin node, eliminating reliance on third-party servers for transaction verification. Multi-key vault configurations distribute signing authority across multiple devices and locations, removing single points of failure. The app is Bitcoin-only, avoiding the complexity and attack surface of multi-asset wallets.
Best For
Bitcoin Keeper is ideal for long-term holders who want robust self-custody without relying on a single key or device. The multisig vault system (supporting configurations like 2-of-3 or 3-of-5) provides protection against key loss or compromise while maintaining full user control.
Families and estate planners benefit from built-in inheritance tools, including time-locked keys via Miniscript that can automatically unlock after specified periods. Collaborative custody features allow trusted contacts like spouses, business partners, or advisors to participate in multi-signature setups without any single party having unilateral control.
Hardware wallet users will appreciate broad compatibility with devices like Coldcard and Tapsigner, enabling air-gapped signing while using Keeper as the coordination layer. Privacy-conscious users benefit from UTXO management tools and the ability to connect their own node. The tiered approach lets beginners start with simple hot wallets before graduating to more sophisticated multisig configurations as their holdings and knowledge grow.
