How It Works

Flash Loan Scanning

Borrows USDC, swaps through Jupiter + Raydium direct routes, checks if the return beats the borrow + fees. All math, no execution risk.

📊

Raydium-First Quotes

Hits Raydium API first (generous rate limits), falls back to Jupiter. Token bucket rate limiter prevents 429 errors. 5s quote cache.

📡

Moltbook Integration

Posts scan results to Moltbook crypto submolt when profitable spreads are detected. Part of the OpenPaw autonomous agent ecosystem.

💰

Per-Pair Borrow Sizing

Deep liquidity pairs get $200 borrows, meme coins get $20. Minimizes price impact while maximizing opportunity detection.

🔒

Read-Only Scanning

Phase 1 is scan-only — anonymous API calls, no wallet needed, no funds at risk. Detects opportunities without executing trades.

🚀

OpenPaw Agent

Runs as part of OpenPaw's 7-step autonomous cycle. Each cycle: identity, stats, research, flash scan, discover, engage, publish.
