MEV protection in Trezor Suite

What is MEV?

MEV (Maximal Extractable Value) refers to the profit that validators, miners, or bots can capture by reordering, inserting, or censoring transactions in a blockchain. This can lead to harmful practices like frontrunning (someone pays a higher fee to get ahead of your trade) or sandwich attacks (traders exploit price slippage around your transaction).

MEV protection is designed to prevent these risks by:

• Routing trades privately so they are not exposed in the public mempool.
• Batching transactions in a way that reduces opportunities for manipulation.
• Working with trusted relays or validators that commit to fair ordering.

The result is safer and more predictable trading for users, with reduced costs and a lower chance of being exploited by arbitrage bots.

MEV protection in Trezor Suite

MEV protection works by routing your transactions through private relays instead of the public mempool, thus shielding your activity from bots and manipulative actors; this reduces slippage, failed transactions, and unnecessary gas costs. This means smoother, more predictable execution for swaps, trades, and transfers in Trezor Suite:

• Safer transactions: avoid front-running, sandwich attacks, and other manipulative strategies.
• Reliable execution: transactions reach the blockchain efficiently, reducing failures and wasted gas.
• Lower costs and slippage: trades and transfers execute closer to expected outcomes.
• Multi-chain support: works on Ethereum, BNB Smart Chain, and Base.
• Full control of your assets: your tokens remain fully under your control while MEV protection handles transaction routing.
