As of #28, we removed the web app to focus first on Android and iOS apps. We will re-add web support later.

The previous web app will remain available temporarily at alpha.thearcapp.com, but will not receive updates.

Documenting on our wiki:

• Authentication
• Fetching events via API

This is pre-alpha and very little works. But if you like bugs and pain, here are the basics:

1. git clone [email protected]:ArcadeLabsInc/arc.git
2. cd arc
3. yarn
4. yarn start

Consult the Expo docs for more details on environment setup, running on device or emulator, and building your own version via EAS.

• Pull requests are welcome to implement any of the above features or do smart refactors.
• We'll pay a bounty of 1 million sats (BTC) to the first three people who submit a non-trivial PR we merge to main, max one per person.
  • Bounty #1 awarded to saltrafael for #41
• If you want ideas for good PRs or to coordinate your work - like you probably shouldn't do a big refactor without checking that we like the general direction - DM us on Twitter.
