# AntiMEV

The MEV tax many traders experience is often avoidable. When trades are submitted on standard AMMs, bots can see them in the mempool and sometimes execute “sandwich attacks” that capture part of the trader’s margin.
On STONfi, the Omniston protocol addresses this with a Request for Quote (RFQ) execution model on The Open Network.
Instead of sending a trade directly into a public pool, the system first requests a private quote from liquidity providers (called resolvers). The trade is executed only after the quote is agreed upon, which reduces the opportunity for bots to interfere.
