What it is, why it matters to swaps, and how to reduce impact.

MEV (Miner/Maximal Extractable Value) is about how transaction ordering can affect outcomes. In simple terms: someone can sometimes profit by seeing your transaction before it’s finalized.

Where you’ll notice it

  • Swaps with low liquidity or tight slippage.
  • Copy-traded or highly popular token pools.
  • Transactions that move a lot of value in one go.

Practical protections

Use reasonable slippage, avoid moving huge amounts at once, and consider routing/limit options when available. If a swap fails, don’t rush—recheck price impact and pool health.

Mindset

Treat every DEX swap as “probabilistic”. You can improve odds, but you can’t remove uncertainty completely.

Not financial advice.
