MEV (Maximal Extractable Value)

Understanding MEV on Solana and how it affects your trades on Axiom.

MEV (Maximal Extractable Value) refers to the profit that can be made by including, excluding, or reordering transactions within a block.

On Solana, MEV usually takes the form of:

  • Front-running: A bot sees your trade and buys ahead of you to sell it back to you at a higher price.
  • Sandwiching: A bot buys before you and sells immediately after you, profiting from the price impact of your trade.
  • Arbitrage: Bots moving liquidity between different DEXs to keep prices consistent.

How to Protect Yourself on Axiom

Axiom provides tools to mitigate MEV impact:

  1. Jito Bundles: Axiom can route your trades through Jito, which prevents public mempool bots from "seeing" your transaction before it's confirmed.
  2. Slippage Control: Keeping your slippage low (under 1-2%) makes it unprofitable for most sandwich bots to target you.
  3. Priority Fees: High priority fees ensure your trade is processed before bots can react in some scenarios.

Solana vs Ethereum MEV

Solana does not have a public mempool like Ethereum, which makes "traditional" sandwiching harder, but advanced bots still use block-engine specialized routes to extract value.
