I’m reaching out about MEV Shield - an open-source, high-performance MEV detection system that could enhance protection for Lido’s validator operations.
Validators face MEV-related challenges in block production and transaction ordering. MEV Shield offers:
Hi Donald, could you explain a bit more in detail how this product would tie into the protocol? Since the majority of blocks are produced using relays, I’m not sure where this would fit in. Additionally, what is it protecting against specifically?
Thank you for your questions - happy to provide more detail.
How this product ties into the protocol:
Our arbitrage detection system is designed to enhance MEV (Maximal Extractable Value) capture for Lido validators by identifying and executing profitable cross-DEX arbitrage opportunities. While relays handle block production, there’s still significant MEV opportunity in the transaction pool that can be captured through sophisticated arbitrage detection.
Where it fits in the relay-based block production flow:
Pre-block construction: Our system monitors multiple DEXs (Uniswap V2/V3, Curve, Sushiswap) in real-time
Opportunity identification: Detects price discrepancies across venues before they’re included in blocks
Bundle preparation: Creates optimized transaction bundles that can be proposed to relayers
MEV sharing: A portion of captured value can be directed back to Lido stakers
What it’s protecting against/solving:
MEV leakage: Ensuring Lido validators capture arbitrage opportunities rather than external searchers
Inefficient execution: Current setups often miss cross-DEX opportunities due to latency or incomplete market coverage
Value left on table: Significant arbitrage opportunities exist between major DEXs that aren’t being fully captured
The system uses real-time blockchain data from your validators’ perspective and can be integrated either:
As a standalone service for Lido node operators
Or as part of the relay infrastructure for enhanced MEV capture
Would you be open to a brief call to discuss potential integration points and demonstrate the system’s capabilities?
