Pyth Sentinel

Team: @Investor_Daniel  
Submitted: March 17, 2026

Answer Capsule :  
Pyth Sentinel is a real-time crypto alert and prediction platform powered  
by Pyth Network. It uses Pyth Price Feeds to deliver live institutional-grade  
prices for BTC, ETH, SOL, BNB, and PYTH, triggers custom alerts via email  
or webhook, and uses Pyth Entropy to power a verifiably fair price prediction  
game. Built to make Pyth data accessible to everyone.

What It Does :  
Pyth Sentinel solves the problem of missing critical crypto price movements  
by letting users set custom price alerts that fire automatically via email  
or webhook when conditions are met, powered by Pyth’s institutional-grade  
price feeds. It features a live price history chart that tracks real-time  
price movement, and a prediction game where users guess UP or DOWN on asset  
prices with outcomes determined by Pyth Entropy for verifiable fairness.

Pyth Features Used

- ✅ Price Feeds (on-chain or off-chain)
- ✅ Entropy (randomness)
- ✅ Both
