Why You Need the Right DeFi Tools

The Complexity Challenge

Modern DeFi traders face:

• Multi-chain complexity: Assets spread across 15+ chains
• Information overload: Thousands of tokens and pools
• Risk management: Smart contract vulnerabilities, IL, price volatility

Problem: Save $5 on token price, pay $20 extra in gas.

Solution: Check Gas Calculator and factor into total cost.

❌ Mistake #4: Hot Wallet for Large Amounts

Problem: $50K in MetaMask → one phishing link = all gone.

Solution: Hardware wallet for >$5K. Non-negotiable.
