# MEV Analysis for Solana DEX Trading

Maximal Extractable Value (MEV) is the profit that validators and searchers can extract by reordering, inserting, or censoring transactions within a block. On Solana DEXes, MEV primarily manifests as sandwich attacks against swaps, cross-DEX arbitrage, and liquidation extraction. This skill covers detection, estimation, and protection strategies.

## What Is MEV on Solana?

MEV occurs when someone with transaction ordering power profits at other traders' expense. On Solana, the MEV supply chain works as follows:

1. **You submit a swap** through an RPC endpoint
2. **Searchers observe** your transaction (via RPC forwarding, block engine access, or leader TPU sniffing)
3. **Searcher constructs a profitable bundle** (e.g., sandwich your swap)
4. **Bundle submitted to Jito block engine** with a tip to the validator
5. **Validator includes the bundle** in the block, earning the tip
6. **You receive worse execution**; the searcher profits the difference
