How it's made
Challenges we ran into ## Challenges I Ran Into ### WHOOP API Integration and Webhook Security 🔐 **Challenge:** Implementing secure WHOOP webhook signature verification while managing OAuth token refresh logic was complex. **Issues Encountered:** - WHOOP webhook signature verification required precise timestamp and raw body HMAC-SHA256 computation. - Managing OAuth token expiration and refresh token flow. - Handling different WHOOP API environments (production vs staging). ### Reward-Based System Challenges **Challenge:** Implementing fair reward calculations based on sleep quality metrics (duration, efficiency, cycles, deep sleep) while preventing gaming and ensuring sustainable tokenomics. **Solution:** - Developed a comprehensive scoring algorithm within the smart contract that accounts for multiple sleep factors. - Implemented daily caps of 10 SLEEP tokens to limit rewards. - Added streak bonuses to encourage consistent good sleep habits.
