trezor_flutter 1.3.0

Trezor hardware wallets in Flutter over native USB and Bluetooth LE, with Codec v1 and the encrypted Trezor-Host Protocol (THP) in pure Dart.

1.3.0

• Web: USB over WebUSB (Chrome, Edge and other Chromium browsers), with connect / disconnect events. New TrezorPlatform.usbRequestDevice() shows the browser's device chooser. Safari and Firefox have no WebUSB: capabilities() reports usb: false there.
• Example app: runs in the browser (USB button opens the device chooser) and explains when USB is unavailable (Safari / Firefox, or a page that is not served over https or localhost).
• Protobuf varints no longer use bitwise operators, which JavaScript limits to 32 bits: values of 2^32 and above (Tron timestamps and amounts) now encode and decode correctly on the web. The whole test suite also passes in Chrome.

1.2.1

• Documentation: Windows in the supported devices table, the architecture diagram and the packaging notes.

1.2.0

• Windows: USB (WinUSB, WebUSB interface) with USB hotplug events. No driver install needed on Windows 10 and later. Bluetooth is not supported on Windows.

1.1.0

• macOS: USB (IOKit, WebUSB interface) and Bluetooth LE (CoreBluetooth), with USB hotplug events. Swift Package Manager and CocoaPods.
• Tron: tronGetAddress, tronSignRawTransaction (signs TronGrid raw_data directly: TRX, TRC-20 and staking / voting / delegation contracts) and tronSignTransaction for explicit fields.
• The raw transaction is checked to be byte-identical to what the device will rebuild and sign, so unsupported transactions fail before reaching the device instead of producing an unusable signature.
• Tron signing messages in package:trezor_flutter/messages.dart.

1.0.1

• Documentation: full feature list and API reference in the README, hardware and test status.

1.0.0

Initial release.

• Native transports: USB (Android, WebUSB interface) and Bluetooth LE (Android, iOS), exposed as a packet pipe (TrezorPlatform, NativeTrezorLink), with USB hotplug and Bluetooth state events.
• Codec v1 protocol for Model One, Model T, Safe 3 and Safe 5.
• Trezor-Host Protocol (THP) for Bluetooth-capable devices: channel allocation, alternating-bit acknowledgement and retransmission, Noise XX handshake, code-entry pairing (CPace), pairing credentials and encrypted sessions.
• TrezorClient: protocol detection, button / PIN matrix / passphrase / pairing-code prompts via TrezorInteraction, cancellation.
• Ethereum: address, EIP-1559 and legacy transaction signing with calldata streaming, EIP-191 message signing, EIP-712 by-hash signing.
• Solana: address, public key, transaction signing.
• Protobuf message classes for management, Ethereum, Solana, Bitcoin, Tron and THP in package:trezor_flutter/messages.dart.
