MEV Protection

MEV Protection Protect your transactions from Maximal Extractable Value (MEV) attacks.

What is MEV?

Maximal Extractable Value (MEV) refers to the value that block producers or observers can extract by reordering, inserting, or censoring transactions within a block. The most common MEV attack is a Sandwich Attack — an attacker front-runs your trade (buys before you), pushes the price up, then back-runs (sells after you) to profit at your expense.

Protection Mechanisms

• Private transaction submission — Transactions are submitted through private channels where supported by the chain, bypassing the public mempool. Attackers cannot observe your trade before execution.
• Slippage protection — Configurable thresholds ensure your trade only executes if the output amount is within your acceptable range. If price deviation exceeds your threshold, the transaction is automatically reverted.
• MEV-aware routing — The AI Router evaluates candidate paths for MEV exposure and preferentially selects routes with lower extractable value, reducing attacker opportunity.
• Private relay integration — For chains that support private relay infrastructure, transactions are submitted directly to block builders, completely bypassing the public mempool.

Intent-Based Routing: Built-in MEV Resistance

WheelX's Intent-based routing provides inherent MEV protection. You only submit the desired outcome ("I want Token B from Token A"), not the execution path. This means:

• No path details exposed — attackers can't predict which route your trade will take
• Internal orchestration — the AI Router selects and executes the path privately
• No manual multi-step signing — each step is handled internally, not submitted to public mempools individually

Benefits

• Prevent sandwich attacks — Private submission and MEV-aware routing eliminate front-run/back-run opportunities
• Reduce value loss from front-running — Transactions that can't be seen can't be exploited
• Fair execution for all transaction sizes — Same protection regardless of trade size
