app-ethereum
Ethereum wallet application framework for Nano S and Nano X.
Ledger Blue is not maintained anymore, but the app can still be compiled for this target using the branch blue-final-release.
This app follows the specification available in the doc/ folder.
To compile it and load it on a device, please check out our developer portal.
Plugins
This app support external plugins. More info in doc/ethapp_plugin.asc. If you wish to have a look at an existing plugin, feel free to check out the ParaSwap plugin.
Testing
Testing is done via the open-source framework zemu.
Running tests
First install yarn. Then you can install the project by simply running:
make test
This will run make install_tests and make run_tests
To run a specific tests (here the send test):
cd tests
sudo jest --runInBand --detectOpenHandles src/send.test.js
Make sure you're in the tests folder before running jest or yarn test.
Adding tests
Zemu
To add tests, copy one of the already existing test files in tests/src/.
You then need to adapt the buffer and tx variables to adapt to the APDU you wish to send.
- Adapt the expected screen flow. Please create a folder under
tests/snapshotswith the name of the test you're performing. - Then adapt the
ORIGINAL_SNAPSHOT_PATH_PREFIXwith the name of the folder you just created. - To create the snapshots, modify the
SNAPSHOT_PATH_PREFIXand set it to be equal toORIGINAL_SNAPSHOT_PATH_PREFIX. - Run the tests once, this will create all the snapshots in the folder you created.
- Put back your
SNAPSHOT_PATH_PREFIXtosnapshots/tmp/.
Finally make sure you adapt the expected signature!
Update binaries
Don't forget to update the binaries in the test folder. To do so, compile with those environement variables:
make DEBUG=1 ALLOW_DATA=1
Then copy the binary to the tests/elfs folder (in this case, compiled with SDK for nanoS):
cp bin/app.elf tests/elfs/ethereum_nanos.elf
Repeat the operation for a binary compiled with nanoX SDK and change for ethereum_nanox.elf.
