Pyth Network has recently launched Express Relay on the mainnet, offering a decentralized solution to combat Miner Extractable Value (MEV) in DeFi transactions. This initiative aims to address the challenges posed by MEV and enhance the efficiency and fairness of blockchain ecosystems.
The Pyth Network specializes in providing real-time market data for blockchain applications, with a focus on securely and affordably bringing latency-sensitive financial data on-chain. Express Relay, their latest product, connects DeFi protocols directly with a network of established searchers through protocol-controlled auctions, effectively eliminating the role of miners and improving market efficiency. Notable searchers integrated with Express Relay include Flow Traders, Wintermute, Auros, Flowdesk, Caladan, Tokka Labs, and Swaap Finance.
MEV Challenges in DeFi
The traditional MEV framework allows miners or validators to capture a significant portion of the value from DeFi transactions through tips for blockspace. However, MEV presents several critical issues for blockchain ecosystems, especially in the DeFi space.
MEV practices can lead to higher transaction costs and network congestion as miners and validators compete to extract value, potentially excluding regular users. Strategies like front-running and sandwich attacks can give unfair advantages to sophisticated actors, undermining trust in the system and hindering wider adoption. Moreover, the centralization of MEV extraction capabilities among a small number of powerful entities threatens the decentralized nature of blockchain networks, as it concentrates power and influence.
In extreme cases, the pursuit of MEV can incentivize malicious behaviors like blockchain reorganizations, jeopardizing the security and integrity of the entire network. These challenges highlight the importance of addressing MEV to maintain the fairness, efficiency, and decentralization of blockchain systems.
Express Relay’s Solution
Express Relay addresses these issues by awarding transaction rights to the searcher with the most competitive bid, effectively removing miners from the equation. This approach encourages fierce competition among searchers for transaction value and enables DeFi protocols to enhance liquidation reward incentives. As a result, protocols can save costs and redirect resources to more productive initiatives or benefit users directly.
Notable protocols like Synthetix, Zerolend, Ionic, Synonym, Keom, Jax Finance, Vela Exchange, and Fulcrom Finance, with a combined total locked value of $1 billion across 11 blockchains, have either integrated with Express Relay or are in the integration process. This integration significantly reduces costs associated with critical operations like setting liquidation rewards.
Express Relay also facilitates the launch of new protocols by providing access to an established network of searchers, eliminating the need for protocols to build their own liquidator and searcher networks. It consolidates valuable DeFi transaction opportunities across various protocols and blockchains for searchers, simplifying access and reducing negotiation and integration costs.
The unveiling of Express Relay took place at the inaugural Pyth Agora 2024 summit during the Ethereum Community Conference on July 11. The initiative is owned and governed by the Pyth DAO, and industry figures like Michael Lie of Flow Traders, Tim Wu of Wintermute, Matt Losquadro of Synthetix, and Ryker of ZeroLend have shown their support for the project.
Wu, Head of DeFi at Wintermute, shared his thoughts on Express Relay:
“Express Relay is a natural evolution from Pyth’s core oracle offering. It aims to reduce value extraction by intermediaries and enhance liquidation execution efficiency, effectively combatting MEV in this form.”
