⚠️ Important Notes & Risks

• Security Risk: Flash‑loan contracts and arbitrage scripts are very risky. They need to be audited and well-tested.
• Scams Exist: Not all GitHub code is trustworthy; always double-check code, test on testnets first, and don’t blindly deploy.
• MEV Front-running: Using flash-loan bots + Flashbots can enable MEV-style strategies — but that space is complex and potentially competitive.
• Gas Costs: Flash operations can be expensive due to gas + repay costs; profit isn’t guaranteed.
