BitBox / Shift Crypto

• Name: BitBox / Shift Crypto
• URL: https://bitbox.swiss/
• Category: hardware-wallet infrastructure / self-custody app-and-backup stack / developer-integrable signing ecosystem
• Tags: bitcoin-ecosystem
• Summary: BitBox is a clean Bitcoin-first hardware-wallet stack: device, companion app, backup flow, and integration surface. The interesting part is the signer-plus-app plumbing and the microSD recovery model, not some grand custody theory.
• What it does:
  • Builds BitBox hardware wallets for offline storage of private keys and on-device transaction signing
  • Offers multiple device variants including Bitcoin-only and multi-asset editions, plus the newer BitBox02 Nova with Bluetooth support for iPhone/iPad
  • Operates the BitBoxApp as the official companion application for desktop and mobile portfolio management, transaction signing, buy/sell flows, and account management
  • Uses a microSD-centered backup and recovery flow, with optional paper or steel recovery-word backup paths
  • Publishes developer resources for integrating the BitBox02 through WebHID, BitBoxBridge, and the Bitcoin Hardware Wallet Interface (HWI)
  • Maintains public firmware, app, bridge, backup-recovery, and client-library repositories for the device ecosystem
• Key claims:
  • The homepage says BitBox hardware wallets store private keys offline and presents the BitBoxApp as “the center of the BitBox ecosystem,” which is a strong signal that the company is shipping a full operational stack rather than only hardware
  • The homepage repeatedly emphasizes instant backup and recovery using the included microSD card, which is one of the clearest differentiators of the BitBox model
  • The homepage says the firmware and BitBoxApp are fully open source, and positions Swiss design/manufacturing plus auditability as part of the trust model
  • The developer-resources page says the BitBox02 can integrate with browser applications via WebHID or BitBoxBridge and with third-party bitcoin wallets via HWI, which makes the project clearly broader than a closed companion-app wallet
  • The developer-resources page documents the secure chip (ATECC608B), open-source microcontroller firmware, physical interaction requirements, and developer devices that can load unsigned firmware for testing
  • The firmware repository says the device uses encrypted protobuf messages and Noise with out-of-band authentication for USB communication, and it exposes public PCB schematics, bill of materials, and x-ray files, which is a strong transparency signal
  • The GitHub organization pins not only firmware and the main app but also backup-recovery, bridge, and client-library repos, reinforcing that BitBox maintains a broader signing-and-recovery ecosystem
  • The BitBoxApp repository shows a multi-layer architecture spanning React UI, Go backend, Qt desktop shell, Android target, simulator support, and configurable server/full-node connections, which is materially richer than a simple companion app
• Whitepaper: No canonical standalone BitBox or Shift Crypto whitepaper/litepaper surfaced in this pass. The clearest current sources of truth were the official site, developer resources, BitBoxApp materials, and the public GitHub organization and repositories; see ../whitepapers/bitbox-shift-crypto-primary-sources-2026-05-01.md.
