@RadiantsDAO What if you had to physically walk somewhere to claim crypto? Finishing touches on Echo Protocol — location-locked SKR on Seeker. See you at the finish line.

Time is ticking ⏲️

@solana Missing one 👀 We're building Echo Protocol — location-locked content and token drops on Solana. Walk to a real GPS coordinate, claim SKR rewards. 207 Echos live across 34 cities on Devnet, built for @solanamobile Seeker. The deep dive hasn't started yet 🗺️

Take a deep dive into a few of the dApps on Solana:

@solana_daily Solana's real edge isn't just speed – it's making crypto usable in the physical world. That's exactly why we're building @EchoProtocol – location-based token rewards you discover by walking around your city. The future is onchain AND on the ground.

🚨 Michael Saylor says the future of programmable digital credit will be deployed on Solana.

The full claim flow in 60 seconds: Find it on the map → Walk there → Sign with Seed Vault → Claim SKR → Verify on Explorer No accounts. No emails. Just location + blockchain. #MONOLITH #SolanaSeeker #Solanamobile

@Iamprexius Yes, the app is built for Seeker. But creators can also run campaigns open to any Solana wallet — Seeker-only enforcement is optional and handled on-chain.
