Comparing OEV Solutions: Chainlink SVR vs RedStone vs API3
Oracle Extractable Value (OEV) has emerged as a key opportunity for DeFi lending protocols like Compound to reclaim value that previously leaked to third-party arbitrageurs. Simply put, OEV is a subset of MEV (Maximal Extractable Value) that occurs when an oracle update triggers actions like liquidations. For example, when a price feed update makes a loan undercollateralized, bots currently race to execute the liquidation and capture the bonus. OEV solutions aim to recapture that value for the protocol and its users, instead of letting it go to miners, validators, or MEV bots.
Every time Compound pays out liquidation bonuses, a large portion of that profit is effectively “leaked” to whoever wins the gas auction to liquidate first. For Compound, this has been a significant loss – by USDC market on Mainnet estimate, over $5M leaked in 2025. By adopting an OEV recapture mechanism, Compound can redirect these funds back into the protocol, strengthening its reserves and benefiting its community, rather than enriching external actors. Potentially, capturing OEV could significantly increase the protocol’s earnings.
This post compares three leading OEV solutions – Chainlink Smart Value Recapture (SVR), RedStone OEV, and API3 OEV-enabled feeds. We’ll cover how each solution implements OEV, technical integration details, trust and security considerations, how the value flows (who gets the profits), current implementation status, and the pros and cons. A final section provides a side-by-side comparison table and an assessment of which solution (or combination) might best fit Compound V3.
What is Oracle Extractable Value (OEV)?
Oracle Extractable Value (OEV) is the profit that can be extracted by controlling the order and timing of oracle price updates and related transactions (e.g., liquidations). OEV is MEV specifically tied to oracle actions. The key idea is that oracles themselves (or DeFi protocols) can capture this value by organizing an auction around the oracle update, instead of leaving it to the block space auction (gas wars). By capturing OEV, Compound can reclaim a portion of the liquidation bonuses that would otherwise go to the fastest liquidator, creating a new revenue stream for the DAO or reserves. All OEV solutions involve an auction for the right to act on fresh oracle data. Instead of a free-for-all race in the public mempool, the oracle provider or protocol orchestrates a controlled auction. The participant (liquidator) who bids the highest wins the right to execute the liquidation using the new price. Their bid becomes revenue that is distributed between the oracle provider and the DeFi protocol.
Now, let’s examine how each of the three solutions implements OEV.
1. Chainlink SVR (Smart Value Recapture)
Overview and OEV Approach
Chainlink SVR helps DeFi applications “recapture” MEV generated by their own price feeds. SVR focuses on lending protocol liquidations and works by delivering price updates in a way that forces liquidators to bid for the right to use those updates. Essentially, Chainlink adds an auction mechanism to its price feeds: before publishing a price update that could trigger liquidations, SVR runs an auction via Flashbots infrastructure. The auction winner (highest bidder) gets to include their liquidation transaction alongside the oracle update.
How it Works
SVR uses dual feeds (Dual Aggregator) for each asset: a standard Chainlink feed updating via the public mempool, and a parallel SVR feed with the same data but delivered through a private channel (Flashbots) with an auction. The auction runs via Flashbots MEV-Share: the Chainlink oracle privately shares the pending price update with “searchers,” who bid for the right to include their liquidation transaction in a “bundle” with the price update. Using Flashbots ensures the price update and the winner’s transaction are included in a block atomically and privately, bypassing the public mempool. A crucial feature is the fallback mechanism: if the auction fails (no bids) or Flashbots delivery fails, the price update is still published via the standard feed after a short delay, ensuring the protocol receives the price. For Compound, integration involves replacing standard Chainlink feed addresses with SVR feed addresses, with no changes to Compound’s core code.
Security & Trust
SVR uses Chainlink’s decentralized oracle network (DON) but adds a dependency on the Flashbots infrastructure. The main risk involves auction or Flashbots failure, but this is significantly mitigated by the fallback mechanism. The price data itself is not manipulated. SVR contracts were developed with input from Chainlink Labs and BGD Labs (known for their work with Aave), and Aave’s integration implies thorough security review, although specific SVR audit reports may not be public. SVR was tested with Aave, and initial usage (reportedly capturing ~40% of liquidation MEV) builds confidence.
Value Flow
The standard revenue split from the auction is 60% to the protocol (Compound) and 40% to the Chainlink ecosystem. Chainlink’s share covers costs and supports network sustainability. Initial partners (like Aave) received better terms (65/35), and Compound could potentially negotiate similar terms. Compound can direct its share to reserves or the DAO treasury.
Implementation Status & Readiness
SVR is live on Ethereum mainnet since early 2025, used by Aave V3. It can be integrated relatively quickly on Compound’s Ethereum mainnet deployment. However, the current version depends on Flashbots and is only available on Ethereum mainnet. It does not work on L2s/sidechains (Base, Polygon, Arbitrum, etc.) where Compound V3 is deployed, until Chainlink releases a cross-chain SVR version or Flashbots expands support.
Pros and Cons of Chainlink SVR
Pros:
- Minimal Change: Easy to integrate, building on existing Chainlink feeds.
- Proven Oracle Quality: Leverages reliable Chainlink data.
- Safety Net: Fallback mechanism reduces failure risks.
- Captures “Non-Toxic” MEV: Focuses on liquidations without harming users.
- Tested in Production: Used by Aave on Ethereum.
Cons:
- Ethereum Only: Major drawback – not yet available on L2s and other chains used by Compound V3.
- Revenue Split (60/40): Compound receives a smaller share compared to API3 (80%).
- Dependency on Flashbots: External reliance on third-party infrastructure.
- Product Immaturity: Less time “battle-hardened” compared to Chainlink’s core feeds.
2. RedStone OEV Solution
Overview and OEV Approach
RedStone is an oracle with a modular architecture known for fast feeds. Their OEV solution emphasizes speed and minimal latency. RedStone runs an auction before publishing the price on-chain. Using its off-chain Data Distribution Layer (DDL), RedStone shows signed prices to liquidators almost instantly. Upon detecting a price that triggers liquidations, a very fast (hundreds of milliseconds) off-chain auction is conducted. The winner (most efficient liquidator willing to give up the largest profit share) gets the right to deliver the price on-chain and execute the liquidation.
How it Works
RedStone separates data collection, signing (off-chain), and distribution via DDL. Liquidators see signed prices before they hit the chain and participate in a fast off-chain auction coordinated by RedStone. The winner (or a RedStone relayer) delivers the price and liquidation transaction on-chain, possibly via specialized relays (e.g., Fastlane on Base) or Flashbots alternatives, avoiding the public mempool. RedStone claims their auction is so fast it adds no perceptible delay to price updates. Importantly, RedStone follows the Chainlink interface, allowing feed replacement without protocol code changes. RedStone’s architecture enables easy deployment on any EVM chain (infrastructure is already on Base). If the auction fails, the price is still updated via RedStone’s standard method.
Security & Trust
RedStone’s data signing model is somewhat more centralized. For OEV, trust is placed in RedStone’s off-chain auction coordinator. The main risk stems from the solution’s novelty. However, RedStone’s core oracle systems have been audited by several leading firms (e.g., ABDK, Peckshield, SigmaPrime), and the OEV solution using UMA OVAL (for the Morpho integration) was audited by Halborn. The “no code change” approach reduces risks for Compound. Failure of the off-chain coordinator could temporarily disable OEV capture, but not the oracle itself.
Value Flow
The proposed split is 50% to the protocol (Compound) and 50% to RedStone. RedStone’s share covers their infrastructure costs (potentially meaning Compound wouldn’t pay separate feed fees). Compound’s share goes to reserves or the treasury. RedStone has also mentioned the possibility of distributing part of the funds to users (at the DAO’s discretion).
Implementation Status & Readiness
The solution is in active development and early deployment. There’s a PoC on Morpho with UMA OVAL (2024), and infrastructure is deployed on Base for a pilot with Moonwell (late 2024). RedStone claims readiness to deploy on all Compound V3 networks without delay. Integration is simple (feed address swap), but the Compound community would need to assess RedStone as a primary oracle provider for the selected markets.
Pros and Cons of RedStone OEV
Pros:
- Cross-Chain Ready: Works on all EVM chains immediately.
- Minimal/No Latency: Very fast auction, potentially speeding up updates.
- No Code Changes: Easy integration via standard interface.
- Potentially More Frequent Updates: OEV incentivizes on-chain price delivery.
- Flexibility & Innovation: New team adapting quickly to the MEV landscape.
Cons:
- Less Battle-Tested: Relatively new solution, less data on performance in major crises.
- Revenue Split (50/50): Lowest share for the protocol among the three options.
- Trust in Newer Oracle: Moving from Chainlink requires evaluating RedStone’s reliability.
- Off-Chain Coordination: Dependency on RedStone’s off-chain system for the auction.
3. API3 OEV-Enabled Data Feeds
Overview and OEV Approach
API3 uses first-party oracles (data directly from providers). Their OEV solution allows an auction at the oracle level before MEV goes to validators. When a price update could trigger liquidations, API3 holds an on-chain auction for the right to publish that update and perform the liquidation. The winner pays their bid, which is split between the protocol and API3. API3 positions this as unlocking “hidden revenue” for dApps.
How it Works
Two types of feeds are used: a global feed (updated by API3 nodes) and an OEV feed (dApp-specific, updated by the auction winner). Compound reads data via a proxy contract that returns the freshest price. When an update is ready, API3 delays the global feed publication by ~30 seconds to allow for an on-chain auction via the OEV AuctionHouse contract. The auction winner must execute the OEV feed price update and their liquidation in one atomic transaction, while simultaneously paying their bid. The mechanism doesn’t require external relays like Flashbots. API3’s solution works on all EVM chains. If there are no bids, the global feed updates automatically after the ~30-second delay. Integration requires pointing to the API3 proxy contract, with no changes to Compound’s code. Compound has already used API3 feeds on Mantle.
Security & Trust
Trust is based on first-party data providers and audited smart contracts for the auction. API3 has undergone over 10 audits of its systems by leading firms, although specific auditors for the OEV contracts weren’t named in the provided sources. The main discussion point is the ~30-second global feed delay, but the system proved reliable during the major market crash in February 2025. The solution has been used in production by multiple protocols (including Compound on Mantle, Mendi, Ionic) for months without incidents. There’s an API3 DAO insurance fund.
Value Flow
The most favorable split for the protocol: ~80% to the protocol (Compound) and ~20% to API3. API3’s share funds data providers and token buybacks/burns. API3 does not charge subscription fees for feeds, using OEV as its revenue model. There are confirmed cases of OEV payouts to protocols (e.g., Yei Finance).
Implementation Status & Readiness
The solution has been live in production since mid-to-late 2024. It’s used by Compound on Mantle (already generated revenue for the DAO), Mendi, Ionic, Yei Finance, and others. It successfully handled the stress test during the market crash. API3 is ready for deployment on all Compound V3 networks immediately. Risk assessors have previously approved API3 data for Compound. API3 actively engages with communities (Compound, Moonwell) and gains approvals.
Pros and Cons of API3 OEV
Pros:
- Highest Revenue Share (80%): Maximum financial return for the Compound DAO.
- Proven in Production: Months of use and successful stress testing.
- Cross-Chain Ready: Unified solution for all Compound V3 networks immediately.
- No Code Changes: Easy integration, confirmed on Mantle.
- First-Party Security: Data directly from sources, reliability proven in practice.
- Forward-Looking: Development of OEV Network (zk-rollup) for greater efficiency.
Cons:
- Switching from Chainlink: May require overcoming inertia and careful evaluation when replacing the main oracle on key markets.
- Global Feed Delay (~30s): A design choice for the auction mechanism. While proven safe in practice, it’s a difference from other approaches.
- Asset Coverage: While broad, API3’s coverage might be smaller than Chainlink’s for very niche assets (though API3 adds new feeds quickly upon request).

Key Considerations for Compound V3
Several key factors should guide Compound V3’s OEV decision. Maximizing revenue is crucial, and API3 leads here with an 80% share for the protocol, potentially meaning millions more for the DAO compared to SVR’s ~60% or RedStone’s ~50%. Given Compound V3’s multi-chain strategy, the immediate availability of API3 and RedStone across all L2s and sidechains is vital, whereas Chainlink SVR is currently limited to Ethereum.
Regarding risk and maturity, API3 has the strongest track record for OEV in production, including surviving stress tests and being used by Compound itself (on Mantle). Chainlink SVR carries Chainlink’s reputation but is newer as a product. RedStone is the newest OEV solution, although its base oracles are audited and used.
Switching from Chainlink on Ethereum markets requires careful consideration, making SVR the path of least resistance there. Finally, the trade-off between latency and speed matters: API3 introduces a controlled ~30s delay for its global feed (proven safe), RedStone promises ultra-fast auctions with no delay, and SVR operates at standard Chainlink speeds.
Possible Strategies for Compound
- Single Provider: Choose API3 or RedStone for all networks for consistency. API3 appears strong due to the best revenue share and proven reliability.
- Hybrid Approach: Use Chainlink SVR on Ethereum (leveraging existing integration) and API3/RedStone on L2s/other chains for immediate coverage everywhere.
- Pilot Projects: Start with pilot implementations on specific, perhaps less critical, markets to gather data before a full rollout.
Conclusion: Compound has a choice among three strong OEV solutions. The decision should align with community priorities: maximizing revenue, immediate multi-chain support, proven reliability, or sticking with established providers. API3 stands out with the best combination of revenue share (80%), multi-chain readiness, and proven performance. Chainlink SVR offers ease of integration on Ethereum and Chainlink’s brand trust, but is limited to one chain. RedStone is compelling for its speed and multi-chain support but offers the lowest revenue share and is less battle-tested. A hybrid approach or phased rollout are also sound strategies. Critically, Compound can significantly boost its economics by selecting and implementing the right OEV solution.
