To audit smart contract DEX integrations for slippage and deadline vulnerabilities, analyze how amountOutMin is sourced and forwarded across multi-hop routes, and verify that deadline parameters protect users against MEV and queue delays. This identifies unfavorable trade risks.

When calling external DEX routers in EVM protocols, check parameter origins, return-value handling, pool and fee tier assumptions, and token approval safety. Verifying these areas prevents unauthorized token spends and mitigates risks from router upgradeability.

Deadline enforcement protects DEX swaps by ensuring transactions execute within a valid timeframe, mitigating MEV extraction and L2 sequencing delays. Analyzing deadline parameters confirms that timing controls actively prevent stale transaction execution.

Yes, you can analyze multi-hop swaps and fee-tier pool assumptions in external DEX calls. The audit evaluates how amountOutMin is enforced across complex routes and validates whether pool selection logic introduces integration risks.

The best way to audit router approval safety for external DEX integrations is to verify token approvals, check for stale approvals, and assess router upgradeability. This process prevents unauthorized token spending and highlights risks from contract upgrades.

External DEX integrations return unfavorable trades despite amountOutMin when parameter forwarding fails across multi-hop routes or fee-tier pools. Auditing return-value handling and parameter origins reveals where slippage enforcement breaks down.
