Reactive Circuit
Build with Reactive at a hackathon, win a prize there, and claim a bonus from us on top. No registration, no separate competition to enter.
How To Claim
[ a ]
Pick a listed event
We publish the events that qualify, but you may suggest yours. Build your project there using Reactive.
[ b ]
Win a prize
Any prize counts: main track, sponsor track, or a regional award. If the organizer has awarded it, it counts.
[ c ]
Claim within a fortnight
Submit the claim form once the event publishes results.
[ d ]
Get paid in REACT
We verify the integration, then send the bonus to the address you provide.
Bonus Size
A bonus of up to 30% of your prize, paid in REACT on top of whatever the event awarded. The exact percentage depends on how relevant the use case is, how well the integration is built and documented, and the scale of the event.
