Here's exactly how: Audit your DeFi smart contract in 3 steps

Step 1: The 'Before You Code' Check

Narrative: I once watched a team skip this and lose $2M. Before writing a line, ask: Does this need to be on-chain? If it's just data sorting, keep it off-chain to reduce attack surface. Action: Map your logic. If it handles funds, it stays on-chain. If not, centralize it. Step 2: The 'Pre-Audit' Bug Hunt

Q&A: Why pay an auditor for simple bugs? You shouldn't. Run static analysis tools first. Action: Use Slither or Mythril. Set it to flag 'uninitialized variables' and 'reentrancy'. Fix these yourself. This turns a $10k audit bill into a $2k review. Step 3: The 'Economic' Stress Test

Narrative: Code can be perfect, but the game theory can fail. Action: Before mainnet, simulate an attack. Ask: Can a whale manipulate the token price in the same block to drain the pool? Use Foundry to fork mainnet and run 1000 block simulations. This catches exploits static analysis misses.
