Echo

Echo: Proof of Seeker is a mobile-first decentralized application that entails authentic human connections through blockchain technology. Built on Solana, Echo combines NFC-enabled peer-to-peer handshakes with token-gated access to create a social networking experience where real-world interactions are verified. Users connect their Solana wallets, verify device ownership, and participate in face-to-face meetups using NFC technology. The app seamlessly integrates with X (Twitter) to share connection moments and update social profiles, while maintaining user privacy through decentralized identity verification. Echo transforms casual encounters into meaningful, building a community of seekers who value genuine human connection in the digital age.
