AdaLite wallet
A very simple Cardano wallet written entirely in JS.
Some disclaimers before we start
AdaLite is not created by Cardano Foundation, Emurgo, or IOHK. The official Cardano team has not reviewed this code and is not responsible for any damage it may cause you. AdaLite does not store your private keys and you are responsible for storing them safely. Please be aware that if your computer is compromised, your mnemonic may be leaked when used as the access method on Adalite. We encourage you to use AdaLite with a hardware wallet for maximum safety. We appreciate feedback, especially a review of the crypto-related code.
Why we are building this
The official Cardano wallet from IOHK runs a full node and takes a long time to sync the blockchain. It's also very big and downloads >500MB of JavaScript dependencies (which can create a large attack surface and requires a lot of auditing). AdaLite is much smaller and is thus much easier to audit. Since it doesn't run a full node or require to sync the entire blockchain it's also very fast. Recovering your wallet from the mnemonic only takes a few seconds.
Validate the source
If you want, you can verify the integrity of the code running in your browser, you can:
- checkout the latest version from the master branch (the one being deployed)
- build the project
- download the source .js from devtools and compare it to the built version
Compatibility with Daedalus/Yoroi
See https://github.com/vacuumlabs/adalite/wiki/AdaLite-FAQ#compatibility-with-other-wallets
Run project locally
Configuration
Prepare .env file
e.g. by cp .env.example .env
Run AdaLite
yarn install
yarn build
ADALITE_ENABLE_HTTPS=true ADALITE_PORT=3000 yarn start-server
Navigate to http://localhost:3000 (or wherever you've configured) and don't forget to set .env to http://localhost:3000 if you were copying the default .env.example file. You may also need to disable caching in your browser to forget previous redirects.
note: ADALITE_ENABLE_HTTPS=true provides a self-signed https certificate, it is recommended to set the flag only when running the app locally.
Development
For development you can start the server with
yarn dev
It runs webpack with the --watch flag and the server with PORT=3000 unless you specify otherwise
Creating releases
For creating releases we use tool release-it, tutorial and setup are written in Releases file
Mocking transaction submission
in .env set the following values (your local settings may differ but by default this should work):
ADALITE_ENABLE_SERVER_MOCKING_MODE = true
ADALITE_MOCK_TX_SUBMISSION_SUCCESS = true
ADALITE_MOCK_TX_SUMMARY_SUCCESS = false
The ADALITE_ENABLE_SERVER_MOCKING_MODE flag tells the server to start in mocking mode to avoid submitting transactions to the actual blockchain. Moreover, it mocks certain blockchain explorer endpoints to fake the transaction submission.
ADALITE_MOCK_TX_SUBMISSION_SUCCESS tells the mock server whether it has to return a success response for tx submission or not.
ADALITE_MOCK_TX_SUMMARY_SUCCESS tells the mock server whether to return that the transaction exists in the blockchain or not - this is useful for polling for transaction status after submission.
Test
lint tests
yarn eslint
unit tests
yarn test
Open app/tests/index.html in browser
Cypress tests
Cypress requires the app to be running with correct environment variables. Type
yarn cypress:dev
to start the app with the correct settings. It calls yarn dev itself, but with correct environment variables for testing.
After that, you can either type
yarn cypress:open
to start the tests with the interactive Test runner, which allows time travel, logs, pausing, etc.
Or, to run the tests in a headless fashion, type
yarn cypress:run
If you wish to create a video of the tests, pass in VIDEO=true yarn cypress:run and videos of all test suites will be created in /app/cypress/videos.

Trezor integration
Some notes on how to implement new coin into Trezor can be found here: https://github.com/vacuumlabs/trezor-core/wiki/Trezor-Development
Hot reloading
Hot reloading is not working well with components that use connect. The project is leading towards removal of connect and its
replacement by useSelector so eventually this issue should be solved.
The issue you can experience with connect is that components would stop receiving state updates and you therefore need to reload the app.
Known issue with unistore and connect
developit/unistore#116
Refactoring
As all projects also this one would appreciate some refactoring love. To save some time on identifying potential source for refactoring see refactoring-proposal.
