APEX ARB v2.1 — USDC/MEME/USDC Arbitrage Bot

What is this?

🚀 ApexArb is a CLI arbitrage bot that scans meme tokens and attempts a round-trip swap (USDC → MEME → USDC) via Jupiter (Free or Ultra).

It calculates net profit (slippage, estimated Jupiter fee, priority fee + Jito tip), applies DEX filters, prints candidates with beautiful log cards, and optionally executes live trades.

✨ Features

• 🔄 Dual quoting: /swap/v1/quote for BUY & SELL.

• 📊 Net PnL calculation with fees & slippage.

• 🎯 Route filtering (INCLUDE / EXCLUDE DEX).

• 🌈 Pretty logs: gradient banner, emoji statuses, boxen cards.

• 🛡 DRY_RUN mode for safe testing.

• ⚡ Jito bundles support.

Troubleshooting

Key missing / format error Ensure exactly one of PRIVATEKEYB58 is present and valid. (.env.example -> .env) 429 Too Many Requests (Jupiter/RPC) Expected under load. The bot uses jitter/backoff automatically; add more/better RPCs. Jito auth/relay issues Verify JITOBUNDLERELAYS and JITO_AUTH. If bundles aren’t available, the bot falls back to sequential mode.

Production Tips

Keep MAX_PARALLEL tuned to your CPU/RPC limits. Use INCLUDEDEXES/EXCLUDEDEXES to filter noisy pools. For ULTRA mode, supply JUPAPIKEY and watch the fees. Enable JITO_MODE=relayer on volatile tokens for better inclusion.
