Crays is built on a Bitcoin-native architecture combining Nostr, RGB, and Lightning to enable decentralized identity, tokenization, and instant peer-to-peer payments without intermediaries.
Inside each partner venue, the Crays Super Node operates as a local mesh hub and Nostr relay, delivering offline-first connectivity, access control, and real-time social discovery through Wi-Fi Aware and Bluetooth mesh networking.
The Super Node hardware uses high-performance components such as RK3588 or Intel N100 processors, Wi-Fi 6E NAN modules, SSD storage, and secure Ubuntu-based firmware to ensure reliability, speed, and privacy.
The Crays App interacts seamlessly with this infrastructure, enabling ordering, matching, payments, and creator monetization — even without internet access — while preserving full user control over keys and funds.
Together, this tech stack forms a global, decentralized hospitality and social network where digital and real-world experiences merge into one unified ecosystem.
