MEV Protection

🛠️ What is an MEV attack?

MEV (Maximal Extractable Value) refers to validators or block builders reordering, inserting, or censoring transactions to extract extra value.

Common attack types:

• Front-running: a trader jumps in before your buy, pushes the price up, then sells for profit

• Sandwich attack: buys before and sells after your trade to profit from the price impact

🛡️ APM’s MEV protection

APM integrates Jito’s MEV protection. You can toggle it in Trading Settings:

• When ON: your transaction is sent only to Jito nodes, reducing exposure to regular validators and mitigating front-running/sandwich attacks

• When OFF: your transaction is broadcast to both Jito and standard block leaders, which can boost speed but lowers protection

Learn more about JITO's MEV solution.

Note: Even with Anti-MEV enabled, attacks can still occur under malicious or misconfigured leaders. Combine it with sensible slippage settings to lower risk.

💰 Validator tip (Bribe)

Jito validators prioritize transactions based on the tip (bribe) paid by the trader.

• Higher bribe → higher execution priority

• In hot or highly volatile tokens, raising the priority fee improves fill probability

APM offers smart fee management:

You set a single total fee (priority fee). APM automatically allocates it across Gas / Priority Fee / Bribe for optimal cost-performance.

📈 Recommendation: When sniping or trading highly volatile tokens, consider raising the priority fee. You can check current tip levels on the Jito Dashboard.
