So I built PythReceipt.</p> <p><strong>What it does</strong></p> <p>PythReceipt creates an immutable, on-chain receipt for every <br> liquidation — stamped with Pyth Network's live oracle data <br> at the exact moment of execution.</p> <p><strong>The Confidence Gate</strong></p> <p>Before any liquidation executes, PythReceipt checks Pyth Pro's <br> confidence interval:</p> <ul> <li>Confidence &lt; 0.2% → ✅ Liquidation allowed</li> <li>Confidence 0.2-0.5% → ⚠️ Warning shown </li> <li>Confidence &gt; 0.5% → 🔴 Liquidation blocked</li> </ul> <p><strong>The Receipt</strong></p> <p>Every successful liquidation generates:</p> <ul> <li>On-chain Solana transaction</li> <li>Live Pyth price at exact moment</li> <li>Confidence interval value</li> <li>Best Bid / Best Ask</li> <li>Downloadable JSON proof</li> </ul> <p><strong>Tech Stack</strong></p> <ul> <li>Next.js 14 + TypeScript</li> <li>Solana Devnet + Anchor</li> <li>Pyth Pro Lazer WebSocket</li> <li>Vercel</li> </ul> <p>Try it: <a href="https://pyth-receipt.vercel.app" rel="noopener noreferrer">https://pyth-receipt.vercel.app</a><br> GitHub: <a href="https://github.com/rajdeblol/PythReceipt" rel="noopener noreferrer">https://github.com/rajdeblol/PythReceipt</a></p> blockchain cryptocurrency showdev web3
