Safety Rules

1. ALWAYS display swap details before execution
2. WARN if price impact > 1%
3. CHECK token allowance before swap
4. VERIFY cross-chain destination address
5. NEVER execute without user confirmation

Error Handling

Error	Cause	Solution
INSUFFICIENT_BALANCE	Low balance	Check wallet balance
NO_ROUTE	No route found	Try different pair
SLIPPAGE_TOO_HIGH	Price moved	Increase slippage
