CLOCK IN: The Solana Mobile Hackathon

Mobile builders, CLOCK IN.
CLOCK IN is the Solana Mobile Hackathon, in partnership with RadiantsDAO. Starting September 8, you’ll have one month to build a mobile-first app for Seeker and compete for $135,000 in prizes.
Build DeFi, payments, games, social apps, consumer products, or something nobody’s built yet. Whether you’re an experienced Solana builder or brand new to crypto, come build with us.
$125,000 in USDC prizes
Ten teams will split $125,000 in USDC:
1st place: $30,000
2nd place: $25,000
3rd place: $20,000
4th place: $15,000
5th place: $10,000
6th-10th place: $5,000 each
Winners must publish their app on the Solana dApp Store to claim their prize. A reasonable timeframe will be provided after the results are announced.
Every winning team also gets:
Featured placement in the Solana dApp Store
Co-marketing and launch support
Seeker devices for the team
A call with Solana co-founder Anatoly Yakovenko
$10,000 SKR integration prize
CLOCK IN also includes a $10,000 prize, paid in SKR, for a creative and meaningful SKR integration.
Use SKR for in-app purchases, staking, rewards, access, or invent your own use case. SKR integration is optional, and the prize is separate from the main USDC prize pool.
Not sure where to start? We pulled together a few SKR integrations from the community in the thread below to inspire you.

Build alongside us
To kick things off after launch, we’ll be joined by the Radiants team on Shipped, the Solana Mobile Livestream by Solana Floor at 11am EST on September 9th. Register here to join us.
We’ll host weekly technical workshops in the Radiants Discord. Drop in, build along, ask questions, and get help as you go. We’ll also dig into AI-assisted mobile development.
You don’t need a Seeker to get started. Build and test on a regular Android device or in an Android emulator, then get your app ready for Seeker.
Start here:
Radiants Discord for workshops and hackathon support
How entries will be judged
Here’s what the judges will look for:
Stickiness and product-market fit: Does the app solve a real problem and give Seeker users a reason to come back?
User experience: Is it intuitive, polished, and actually fun to use?
Innovation: Does it bring a fresh idea or a new way to use mobile?
Presentation and demo: Can you show us what you built and why it matters?
