Understanding Oracle Extractable Value (OEV)
Understanding Oracle Extractable Value (OEV)
🤔 Oracle drama unfolding
Oracle Extractable Value (OEV) is a type of MEV related to oracle updates. It arises from price updates triggering liquidation bonuses on lending protocols, causing some updates to be more valuable than others. Annually, lending protocols across chains lose millions to OEV.
@OEVNetwork proposes a Layer 2 solution to recapture OEV:
- Eliminates most lost OEV
- Maintains user experience
- Preserves data feed security
- Returns captured OEV to dApps
This solution integrates with API3's data feeds, allowing dApps to recapture lost value. It optimizes liquidations and improves protocol performance while maintaining security.
OEV-aware oracles represent an evolution in oracle architecture, potentially fostering innovation and new business models in the lending protocol space.
What is oracle extractable value, or OEV❓ Here’s a short thread to understand the basics and to learn why solving OEV will disrupt the oracle landscape. 🧵
OEV Network Cuts Arbitrum Auction Times in Half
**OEV Network is reducing auction lengths on Arbitrum from 30 seconds to 15 seconds**, scheduled for Monday, September 8 at 10:00 UTC. The network has maintained **100% uptime over 9+ months** with more than 1,500 auctions completed. The upgrade aims to speed up the auction process while maintaining system reliability. - Auction time: 30s → 15s - Target date: Sept 8, 10:00 UTC - Expected minimal downtime - Updates via OEV Discord Channel OEV Network allows MEV searchers to bid for valuable price updates, with auction proceeds returning to the originating dApps.
API3 Pauses Services on Two Networks Due to Technical Issues
**API3 announces service changes** affecting two major networks: - **Polygon zkEVM Mainnet Beta** will be discontinued by Polygon due to technical challenges and strategic shifts - **Kava Chain** feed maintenance will be paused until demand increases **Action Required:** Developers must **update their integrations by September 11, 2025** to avoid service disruptions. This follows Polygon's previous servicing updates aimed at improving network performance and stability. The zkEVM beta shutdown represents a significant shift in Polygon's technical strategy. *Builders should review their current integrations and plan migration strategies accordingly.*
Morpho Labs and Yearn Finance OEV-Boosted Vault Update
Morpho Labs and Yearn Finance continue their collaboration on OEV (Maximal Extractable Value) recapture through their joint vault initiative. The OEV-Boosted USDC vault has shown significant growth since its launch, surpassing $10M in deposits. Key points: - Partnership focuses on returning value to users - Vault specifically designed for USDC deposits - Plans include expansion to additional markets and chains - Aims to provide sustainable yield opportunities Visit [Morpho's OEV-Boosted Vault](https://app.morpho.org/ethereum/vault/0x68Aea7b82Df6CcdF76235D46445Ed83f85F845A3/oev-boosted-usdc) to learn more.
ETHPrague Conference to Address DeFi Value Recapture Through OEV
The upcoming ETHPrague conference (May 27-29) will feature discussions on Optimistic Execution Value (OEV) in DeFi protocols. The event aims to educate developers and protocol owners about: - Methods to recapture value currently being lost in DeFi operations - Implementation strategies for OEV integration - Revenue enhancement opportunities for protocols The conference follows a successful presentation at ETH Bratislava, where similar topics were explored. Attendees can find representatives for detailed discussions by looking for Api3-branded participants.
Oracle Migration Guide: Earn Rewards and Enhance Security
A new migration guide helps lending protocols transition from Chainlink to API3, offering multiple benefits: - Earn revenue through Oracle Extractable Value (OEV) Rewards - Enhance security with multi-oracle support - Seamless upgrade process that maintains system stability The guide comes as lending protocols increasingly recognize untapped revenue potential in oracle services. @MetisDevs workshop provides implementation support for protocols looking to upgrade their oracle infrastructure.
