Every unprotected transaction leaks value. YoorQuezt intercepts attacks, captures backrun MEV, and returns 90% to users. One RPC URL. Zero code changes.
The Problem
When you swap tokens, bots place orders before and after yours to profit from the price movement. Sandwich attacks happen on every chain, every DEX, every block.
Most MEV value is captured by searchers and block builders. On most chains, none of it flows back. Your slippage is someone else's profit.
Existing solutions are single-chain and centralized. No protocol protects transactions across every chain with a decentralized relay network.
The Protection Architecture
Construct high-performance bundles and route them through the YoorQuezt relay mesh. Sealed-bid auctions ensure fair execution and maximum value capture.
$ yqctl bundle submit \ --chain ethereum \ --txs 0xa3f...2c1,0xb7e...9d4 \ --priority high Bundle submitted: 0xf8c...3a2 Bid: 0.023 ETH | Position: 1/12 Status: PENDING_INCLUSION
Protect users and redistribute execution value through programmable Order Flow Auctions. 90% of captured value flows back to transaction originators.

Solve complex transaction intents across chains with programmable routing. Competitive solvers discover optimal paths through multi-hop DEX aggregation.
Intent: Swap 10 ETH -> USDC Chain: Ethereum -> Arbitrum Solver 1: Uniswap V3 -> Bridge -> GMX Solver 2: 1inch -> Stargate -> Camelot Solver 3: Balancer -> Hop -> Uniswap V3 Winner: Solver 2 (+0.42% improvement) Intent solved in 2.1s

How Execution Works
User submits a swap, bridge, or transaction intent through any connected wallet or dApp.

Q AI · MEV Intelligence
Q watches your transactions in real time, explains what MEV bots are doing, suggests better execution strategies, and alerts you when something looks off. Think of it as an AI assistant that speaks DeFi.
Watches the mempool for sandwich attacks and frontrunning in real time. Learns new attack patterns as MEV bots evolve their strategies.
Packages your transactions into optimized bundles. Predicts gas prices and picks the best moment to submit so your bundle wins the auction.
Finds the best way to execute your intent. Compares routes across DEXs and chains to get you the best price with the least slippage.
Monitors all mesh nodes, relays, and services. Detects issues before they cause downtime and auto-scales infrastructure under load.
Differentiation
The only protocol delivering MEV protection across every major chain
More relay nodes = faster propagation, better MEV capture, higher rebates. A self-reinforcing flywheel that compounds with adoption.
Own the full stack: P2P transport, MEV engine, AI intelligence, user-facing proxy. No dependency on third-party relays or centralized infrastructure.
Purpose-built for L2s and alternative L1s where zero MEV infrastructure exists today. First-mover advantage on every expansion chain.
Roadmap
Building MEV protection infrastructure for every chain
Testnet is live. SDKs are ready. The protocol is open source.
