When doing Ethereum signTypedData, and the primaryType="EIP712Domain",
we completely ignore the "message" part and only sign the domain.
According to the community, this is technically allowed by the spec,
and may be used by ETH smart contracts to save on gas.
Test case generated by @MetaMask/eth-sig-util's library.
See: https://ethereum-magicians.org/t/eip-712-standards-clarification-primarytype-as-domaintype/3286
Based on original contribution by Max Kupriianov <xlab@hey.com>
Implemented EIP-712 typed data signatures in Ethereum app.
Add eth_abi into pyproject deps
device test for EIP 712
fixed hex decoding for address
fixup! fixed hex decoding for address
code quality, more pythonic code, removing unused imports
running black and isort on changed files
trezorctl file input for EIP 712 data signing
fixup! code quality, more pythonic code, removing unused imports
fixup! fixup! code quality, more pythonic code, removing unused imports
necessary changes after rebase to master
unit tests for sign_typed_data.py
new protobuf messages, working for nonarray types
simplified and verified solution for our simple data
support for simple arrays, without their confirmation
reverting protobuf value messages to bytes, appropriate changes
showing arrays in Trezor, code quality improvements
data validation on Trezor, minor improvements
using custom types for storing type data instead of dicts, addressing feedback from review
moving helper functions to its own file, tests for decode_data
additional overall tests
support for arrays of structs
adding support for metamask_v4_compat variable
using HashWriter object to collect the final hash continously
minor improvements in code quality
validate_field_type function
streaming values from client without saving them, missing UI
prototype of streamed UI using confirm_properties
accounting for bytes in data, more data types in integration tests
rebase on master, using f-strings
minor fixes and improvements from code review
StructHasher class for the whole hashing process
mypy and style changes
asking users whether to show structs and arrays
protobuf descriptions to fix make defs_check
unifying comments, mypy fix
unit tests for StructHasher class
UI fixtures, skipping device tests for T1
addressing majority of code review comments about code quality and structure
changing file structure - layouts, helpers, sign_typed_data
decode_data renaming and docstring, renaming unit test file
using tuples instead of lists in elifs
layout improvements
excluding core/src/apps/common/confirm.py file from the PR
True/False returning layout with Show more button
code review layout improvements
forgotten br_type argument to should_show_more
Relevant micropython commits:
d1bfb271d7686708fe8711a177629c8bf6e7f6a6 lib/uzlib: Move uzlib code from extmod to lib.
4d546713ec8858cbf908de45de11cbfc46a20971 shared: Introduce new top-level dir and move 1st party lib code there.
ca920f72184c50f61002aa9d5cd01555b1e28b7b py/mpstate: Make exceptions thread-local.
* Changes from original PR
* Now that we are rejecting chain_ids of 0, we need to have the tests set the chain_ids to at least 1.
* Ran 'make gen' and uploaded changed files.
* Ran make style_check and fixed reported errors
* Added changelog files
* Reverted changes concerning chain_id 0 being rejected.
* Adds tests for MAX_CHAIN_ID and MAX_CHAIN_ID+1. Also reverts MAX_CHAIN_ID to the previous value.
* Added missing whitespace around arithmetic operator.
