Security Model
Mobile-first Bitcoin-only self-custody system using 2-of-3 multisig, a hardware key, an app key, a Block-managed server recovery key, fingerprint-gated hardware approval, device verification, cloud backup, recovery contacts, delay-and-notify recovery, and an emergency exit kit instead of a seed phrase.
Trust Assumptions
- Users trust Block's Bitkey software, app distribution, and server-cosigner infrastructure
- Block's server key cannot move funds alone but remains part of normal recovery and optional low-limit transfer workflows
- The app key backup remains encrypted and recoverable through the user's cloud account
- NFC pairing and device-verification flows remain correctly implemented
- Users verify transactions and security settings on the Bitkey device display before approval
- Users understand Bitkey intentionally does not provide a traditional seed phrase backup

Known Issues
2024: Seedless recovery and server-cosigner debate
Bitkey rejects traditional seed phrases in favor of a managed 2-of-3 multisig recovery model, which improves usability but creates dependence on Block infrastructure and recovery processes.
2026: Generational hardware transition
Current Bitkey marketing and official pages describe a newer $250 device with on-device display verification, while older retail listings and pages still show the earlier $150 NFC-only hardware, so users must verify the exact generation before purchase.
