- // 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.
- // 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.
