Shrimpy - Your thoughts, sealed.

Shrimpy is a privacy-first mental wellness journal for writing down thoughts, tracking moods, and preparing for meaningful conversations with a therapist.

Journal entries are encrypted on the user’s device with Sui Seal before storage on Walrus. Private AI reflections run through 0G Private Computer in a TEE. Users remain in control: they choose exactly what to export and share.

Built with

  • Next.js, React and TypeScript
  • Sui zkLogin for familiar Google sign-in without an exposed wallet
  • Sui Seal for threshold encryption and revocable access control
  • Walrus for durable encrypted blobs
  • 0G Private Computer for private AI reflections

Hackathon targets

  • 0G — Best AI Product on 0G: 0G Private Computer is the private inference layer behind Shrimpy’s opt-in reflections.
  • Sui — Best app built on Sui: zkLogin, Seal and Walrus are core to onboarding, encryption, sharing and storage.

Walrus blobs are publicly retrievable but contain ciphertext only; blob identifiers and timing are not treated as secrets. Revoking access prevents future decryptions, but cannot retract an export already copied by a recipient.

Disclaimer

Shrimpy is a reflective wellness tool. It does not provide medical advice, diagnosis, treatment, or emergency support.
