// This file contains the implementation for interacting with the Trezor hardware
// wallets. The wire protocol spec can be found on the SatoshiLabs website:
// https://doc.satoshilabs.com/trezor-tech/api-protobuf.html
// https://wiki.trezor.io/Developers_guide-Message_Workflows
//go:generate protoc --go_out=import_path=trezor:. types.proto messages.proto
// !!! STAHP !!!
//
// Before you touch the protocol files, you need to be aware of a breaking change
// that occurred between firmware versions 1.7.3->1.8.0 (Model One) and 2.0.10->
// 2.1.0 (Model T). The Ethereum address representation was changed from the 20
// byte binary blob to a 42 byte hex string. The upstream protocol buffer files
// only support the new format, so blindly pulling in a new spec will break old
// devices!
//
// The Trezor devs had the foresight to add the string version as a new message
// code instead of replacing the binary one. This means that the proto file can
// actually define both the old and the new versions as optional. Please ensure
// that you add back the old addresses everywhere (to avoid name clash. use the
// addressBin and addressHex names).
//
// If in doubt, reach out to @karalabe.
// Package trezor contains the wire protocol wrapper in Go.
// To regenerate the protocol files in this package:
// - Download the latest protoc https://github.com/protocolbuffers/protobuf/releases
// - Build with the usual `./configure && make` and ensure it's on your $PATH
// - Delete all the .proto and .pb.go files, pull in fresh ones from Trezor
// - Grab the latest Go plugin `go get -u github.com/golang/protobuf/protoc-gen-go`
// - Vendor in the latest Go plugin `govendor fetch github.com/golang/protobuf/...`
//go:generate protoc -I/usr/local/include:. --go_out=import_path=trezor:. messages.proto messages-common.proto messages-management.proto messages-ethereum.proto
// Package trezor contains the wire protocol.
