API3’s Next-Generation Oracle Stack is live on Zircuit
The API3 Oracle Stack is now available for developers on Zircuit.

We are excited to announce that API3’s Oracle Stack is available on Zircuit, giving developers access to decentralized data feeds (dAPIs) and the OEV Network to recapture protocol MEV due to oracle updates. Developers on Zircuit can now access decentralized data feeds powered by first-party oracle nodes, which are operated directly by the data providers.
With OEV Network being integrated with all of API3’s decentralized data feeds, Zircuit developers will have a built-in mechanism for recapturing MEV. Rather than protocols leaking value to searchers and block builders, the proceeds from oracle update auctions are programmatically returned to the dApp where the value originated, leading to better execution for users and better protocol performance for dApps.
Zircuit is a fully EVM-compatible zero-knowledge (zk) rollup that is redefining the possibilities within the web3 ecosystem. By leveraging pioneering research and state-of-the-art technology, Zircuit offers developers and users unparalleled performance, security, and ease of use. Over the past year and a half, Zircuit has been at the forefront of research in rollup security tooling, rollup compression, and scaling cryptography, earning multiple L2 research grants from the Ethereum Foundation.
Zircuit’s standout feature includes its pioneering sequencer-level security, which monitors the mempool for malicious transactions to prevent their inclusion in blocks. Through its built-in, automated AI techniques, Zircuit protects users from smart contract exploits and malicious actors. Bolstered by its strong security infrastructure, Zircuit is the central hub for restaked assets featuring unparalleled security and allowing users to earn industry-leading yields natively. Zircuit is the premier liquidity hub for restaked assets (ETH, BTC, LSTs, and LRTs) where users enjoy stronger security guarantees and trust.
Developers looking to utilize dAPIs on Zircuit can visit the API3 Market. The API3 Market provides an easy way to browse, access, and manage a wide variety of data feeds, including popular cryptocurrencies, LSTs, LRTs, and stablecoins.
Simply Read Verifiable, Decentralized Data to Power dApps
API3’s first-party oracle architecture maintains data onchain directly from the data providers. This decentralized and verifiable design eliminates rent-seeking middlemen and offers a more secure and efficient method for bringing data onchain.
One of the key benefits of dAPIs is the ease of use for dApps and chains requiring oracle services. Rather than having to manage their own infrastructure, dApps can simply read data that is natively maintained on Zircuit. This solution makes it easy for dApps to quickly and easily migrate to Zircuit from other EVM-compatible chains, allowing for the rapid adoption and scaling of DeFi ecosystems.
API3’s first-party oracle architecture leverages data directly from the source. The oracle nodes are operated by the data providers themselves, bringing cryptographically signed data onto the blockchain. This allows dAPIs to be verified down to the API parameters and aligns with core principles of the blockchain ethos of transparency and onchain verification.
Protocols like Aave, Compound, and various DEXes all rely on data maintained directly on the consumer chain. API3 addresses this need by maintaining data on the native-chain in a verifiable and decentralized way. With the introduction of dAPIs on Zircuit, developers gain direct access to a wide assortment of real-time data straight from the source.
OEV Network: An Application-Specific Solution to Recapture MEV
DeFi protocols that rely on oracles leak a lot of MEV. For protocols like lending dApps, this amounts to millions of dollars a year.
OEV Network creates an efficient market where oracle service providers and searchers come together to combat the negative impact of MEV through specialized order-flow auctions. With OEV Network, searchers don’t need to wait for the price to update onchain, they can trigger the price update when it is most valuable. As an application-specific solution, it captures all the MEV created at the protocol level due to oracle updates and gives it back to the dApp that generated the value.
OEV Network gives every lending and borrowing protocol on Zircuit a built-in MEV solution by improving upon critical inefficiencies in the current oracle design space. By leveraging the security of a Layer 2 to create an efficient market for oracle updates, it not only improves the health of lending and borrowing dApps but also allows them to capture a multi-million dollar opportunity.
