Oval Enables Lending Protocols to Capture Oracle Extractable Value (OEV) through MEV-Share Auctions
Oval, a solution developed by UMA in collaboration with Flashbots, allows lending protocols to capture a significant portion of the Oracle Extractable Value (OEV) generated during liquidations that was previously lost to the MEV supply chain. Oval runs order flow auctions in Flashbots' MEV-Share to effectively price liquidations and redirects up to 90% of the OEV back to the lending protocols. This helps lending protocols reclaim lost value, improve capital efficiency, and generate revenue from liquidations. The integration of Oval with Chainlink Data Feeds simplifies MEV capture without the need for code changes.
Oval helps lending protocols capture millions of dollars of free money each year. But MEV capture is only possible thanks to the infrastructure built by Flashbots. Oval is the first application built on Flashbot鈥檚 MEV-Share protocol. Here鈥檚 why that matters.馃馃憞 Flashbots is
Liquidations are an essential component of DeFi lending. However, they are broken. Current models cause lending protocols to leak millions of dollars of value each year. Oval is a solution to this problem. Read on to learn why. 馃 Permissionless lending is one of DeFi鈥檚 most
Ready to become the first liquidator to use Oval? We're running a Capture the Flag competition to test Oval liquidations. Submit bundles to liquidate test honeypots and win. 馃挵 Starts on Monday, Feb 19th.
With Oval, lending protocols can instantly start capturing OEV. No changes to the contract code, no re-audits, and no re-deployments necessary. It鈥檚 a simple plug-and-play solution that鈥檚 compatible with any EVM-based protocol. 馃 @chrismaree_ @hal2001 @therollupco
Permissionless liquidations are one of DeFi鈥檚 most crucial innovations. But they鈥檙e broken. To understand why, we must look to one of DeFi鈥檚 most successful use cases: lending protocols. In DeFi, demand for loans is high because people want leverage. Lending protocols can
MEV is a HUGE topic in the Ethereum ecosystem. With Oval, lending protocols can capture millions of dollars worth of MEV from oracle updates. This is known as Oracle Extractable Value, or OEV for short. Here鈥檚 a quick primer to OEV and how Oval is set to change DeFi forever.
Lending protocols are overpaying for liquidations. The amount overpaid doesn't secure the protocol. It gets lost to the MEV supply chain. With Oval, the market sets the price of a liquidation and the difference goes to the protocol as revenue. Hear more from @hal2001.
Capture the OEV you're losing today. Oval is built on top of Chainlink Data Feeds to make MEV capture easy. Lending protocols can earn millions in revenue without changing a line of code.
UMA Surpasses Monthly 2022-2023 Assertion Volume in Single Day
UMA has already exceeded its typical monthly assertion volume from 2022/2023 on just the first day of October 2025. **Key metrics:** - 2022/2023: ~500 assertions per month - October 1, 2025: Already surpassed 500 assertions - September 2025: Over 22,000 assertions (20% of all-time total) - Total milestone: 100,000+ assertions reached This dramatic acceleration shows UMA's oracle network experiencing unprecedented growth, with daily volumes now matching what previously took entire months to achieve.
馃敭 Oracle Milestone
**UMA's Optimistic Oracle reaches $50 billion milestone** The decentralized oracle has secured over $50 billion in Total Transaction Value across its ecosystem: - **Across Protocol**: $31.6B in cross-chain transactions - **Polymarket**: $18.7B in prediction market volume - **oSnap**: $111M in governance transactions The platform has processed **170 million transactions** total, doubling its value from $25B earlier this year. This growth highlights increasing adoption of optimistic oracle technology for securing cross-chain bridges, prediction markets, and DAO governance systems.
馃敀 UMA Secures Two Top Polygon Protocols
**UMA's optimistic oracle technology** now secures two of the top ten protocols operating on Polygon's network. This milestone demonstrates **growing adoption** of UMA's oracle solutions within the Polygon ecosystem. The protocols join other major platforms like Polymarket in leveraging UMA's security infrastructure. - UMA provides optimistic oracle services for decentralized applications - Two major Polygon protocols now rely on UMA's security model - Reflects broader trend of oracle adoption in DeFi The integration highlights **UMA's expanding role** in securing critical Web3 infrastructure across multiple blockchain networks.
