BOND addresses a critical gap in the way people connect and engage in physical spaces. While online platforms facilitate virtual connections, discovering and bonding with individuals nearby remains a challenge, especially in spontaneous settings like malls, conferences, or social gatherings.

Real-Time Location Verification
Challenge: Ensuring users in the same geographical area could discover each other without exposing precise location data.
Solution:

Utilized zkProofs (Zero-Knowledge Proofs) to validate proximity without revealing exact coordinates.
Implemented a geohash-based system, where user locations are hashed and matched to a common geofence.

UI/UX for a Mobile-First Design
Challenge: Designing a mobile-friendly interface that feels natural on both mobile and desktop devices.
Solution:

Adopted a mobile-first approach with fixed container widths and a responsive design that mimics a mobile app, even on larger screens.
Iterated on feedback from testing to ensure buttons and interactions were touch-friendly.

Token Distribution Logic
Challenge: Automatically issuing TryBond tokens upon meeting another user required a secure and gas-efficient smart contract.
Solution:

Developed a custom smart contract that verifies proximity and interactions on-chain before minting tokens.
Optimized gas usage by batching transactions and using events for updates.
