What Is MEV and Why Should DeFi Traders Care?

MEV — Maximal Extractable Value — is the profit that validators and bots extract by reordering, inserting, or censoring transactions within a block. The most common attack is the sandwich attack: a bot sees your pending swap, buys the token before you, lets your trade push the price up, then immediately sells for a profit at your expense.

On a $10,000 ETH swap with 0.5% slippage tolerance, a sandwich attack can cost you $30–150 per transaction. If you're an active DeFi trader making multiple swaps per week, that's hundreds of dollars per month silently drained from your portfolio. MEV protection routes your transactions privately so bots never see them in the mempool.

AlphaTerminal goes further. On the Elite plan, our back-run engine participates in the same MEV capture that bots perform — but on the block after your transaction, not before it. We capture back-run MEV and share 50% directly with you. You go from losing money to MEV to earning money from it. See the live MEV dashboard to watch it in real time.

Coverage spans Ethereum, Arbitrum, Optimism, and Base. Connect your wallet or integrate with the AI Account Abstraction system for automatic protection on every transaction.
