# DEXs & AMMs

Decentralized exchanges are targets for price manipulation, sandwich attacks, and liquidity exploits.

## Key Risks

* **Price manipulation** via flash loans or large trades
* **Sandwich attacks** extracting value from user swaps
* **Liquidity removal** draining pools unexpectedly
* **Pool parameter changes** modifying fees or weights maliciously

## Guards We Deploy

**Pool Manipulation Detection** — Alert on abnormal price movements within single transactions.

**Flash Loan Monitoring** — Flag transactions combining flash loans with large outflows.

**Liquidity Drop Alerts** — Detect sudden liquidity removals that could impact trading.

**MEV Protection Monitoring** — Track sandwich attack patterns affecting your users.
