@trezor/transport

NPM

Library for low-level communication with Trezor.

Intended as a "building block" for other packages - it is used in trezor.js (deprecated) and @trezor/connect.

You probably don't want to use this package directly. For communication with Trezor via a more high-level API, use @trezor/connect.

What is the purpose

  • translate JSON payloads to binary messages using protobuf definitions comprehensible to Trezor devices
  • chunking and reading chunked messages according to the Trezor protocol
  • exposing single API for various transport methods:
    • Trezor Bridge
    • WebUSB
