The official open-source firmware monorepo for Trezor hardware wallets, containing firmware for Trezor One and Trezor T/Safe devices, a standalone cryptography library, coin definitions, and a Python client library with the trezorctl CLI. It is the complete source needed to build, audit, and test Trezor device firmware.

Use cases

• build or audit trezor hardware wallet firmware
• verify that my trezor device runs genuine open-source code
• control a trezor device programmatically from python
• add support for a new cryptocurrency to trezor
• contribute to hardware wallet security research
• run firmware tests for a trezor device

When to choose

• you own or develop for Trezor hardware wallets and need official firmware or tooling
• you want to audit the security-critical code of a hardware wallet
• you need the Python client library or trezorctl to interact with Trezor devices

When to avoid

• you need firmware for other hardware wallet brands like Ledger or Coldcard
• you just want a software crypto wallet without dedicated hardware
• you want a ready-made end-user app rather than firmware and developer tooling
