MEV (Maximal Extractable Value) is the profit that can be extracted from blockchain users by reordering, inserting, or censoring transactions within a block.
In simple terms: when you submit a swap on Uniswap, bots can see your pending transaction in the mempool and exploit it before it's confirmed.
Common MEV Attacks
Sandwich Attacks
The most common form of MEV. A bot sees your swap, places a buy order before yours (driving the price up), then sells after your trade completes — pocketing the difference. You end up paying more than you should.
Frontrunning
A bot copies your transaction but with a higher gas fee, getting it included first. This is common with arbitrage opportunities and large trades.
Backrunning
After your trade moves a price, a bot places a trade immediately after to capture the resulting arbitrage. Unlike sandwiching, this doesn't harm you — and YoorQuezt captures this value and rebates it to you.
How YoorQuezt Protects You
- Private routing — Your transaction never hits the public mempool, so bots can't see it
- Sealed-bid auctions — Searchers bid privately to backrun your transaction. No information leakage.
- 90% rebates — The winning bid's value is split: 90% returned to you, 10% to the protocol
The Scale of the Problem
- $2B+ extracted from users annually across Ethereum, L2s, and Solana
- Every chain with a public mempool is affected
- Every DEX trade is a potential MEV target
Why Existing Solutions Fall Short
