I Built Cryptographic Proof for DeFi Liquidations Using Pyth Network

Every time I got liquidated in DeFi, I had one question —
was that price actually fair?

There's no way to verify. So I built PythReceipt.

What it does

PythReceipt creates an immutable, on-chain receipt for every
liquidation — stamped with Pyth Network's live oracle data
at the exact moment of execution.

The Confidence Gate

Before any liquidation executes, PythReceipt checks Pyth Pro's
confidence interval:

• Confidence < 0.2% → ✅ Liquidation allowed
• Confidence 0.2-0.5% → ⚠️ Warning shown
• Confidence > 0.5% → 🔴 Liquidation blocked

The Receipt

Every successful liquidation generates:

• On-chain Solana transaction
• Live Pyth price at exact moment
• Confidence interval value
• Best Bid / Best Ask
• Downloadable JSON proof

Tech Stack

• Next.js 14 + TypeScript
• Solana Devnet + Anchor
