Pyth Sentinel

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.
