what's Bitcoin Keeper?

BBitcoin Keeper is a community-led, open-source mobile wallet app exclusively for Bitcoin, designed to enable secure self-custody through multisig configurations that distribute keys across multiple devices and hardware wallets, eliminating single points of failure. It supports integration with popular hardware like Coldcard and Trezor, Miniscript-enhanced vaults for complex spending policies, coin control, transaction labeling, Tor privacy, and personal Electrum servers. The intuitive interface guides users from basic hot wallets to advanced setups, with free tier access to unlimited wallets, collaborative custody, and direct Bitcoin purchases without KYC or subscriptions. A standout feature is its emphasis on longevity and inheritance planning, offering time-locked vaults, duress keys, emergency access mechanisms, and tamper-evident recovery runbooks for heirs. Paid tiers provide encrypted cloud backups, canary wallets for monitoring, and concierge onboarding. Fully non-custodial, keys remain solely on user devices, aligning with Bitcoin's ethos of sovereignty while prioritizing usability for individuals and families managing generational wealth.
