We just took 2nd place at the MONOLITH Solana Mobile Hackathon 🏆 Feels surreal 🎊 €10K prize for a protocol that rewards real-world exploration on-chain. 207 Echos across 34 cities. 16 on-chain instructions. Huge respect to @RadiantsDAO and the Solana ecosystem for building spaces where solo founders can compete. @solanamobile @solana This is just the beginning!

There are rewards hidden in your city that only your Seeker can see. We built Echo Protocol for exactly that. Mainnet beta drops this month.
