Trends in Crypto Exchange and Digital Wallet Security
The article was written in March , and in between, MetaMask introduced a breaking change. The codebase has since then been updated to support the breaking change.
As such, the snippets in the article might not be exactly the same as the updated code today. The login flow however is still exactly the same. If you want to see the original code, please visit the original branch.
It's really a demo, so I tried to use as few libraries as possible, and the most popular ones when possible. The simplest way to get started is to launch the demo using Docker Compose. Alternatively you could launch docker the containers manually, or run the node services using yarn. This will setup the bakcend listening on localhost and the frontend on localhost The backend should be running on localhost , and the frontend on localhost Since this project is a demo, I haven't written any tests for it.
Only code linting is performed, via eslint and prettier, which you can run using yarn lint. If you liked this demo, I appreciate donations. Skip to content. Star MIT License. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
