API3’s First-Party Oracle Infrastructure is Live on Ink

We are excited to announce that API3’s Oracle Stack is available on Ink, giving developers access to over 190 data feeds on the API3 Market and the OEV Network to recapture protocol MEV due to oracle updates. Developers on Ink can now access verifiable, multi-source, decentralized data feeds (dAPIs) powered by first-party oracle nodes, which are operated directly by the data providers. 

With OEV Network being integrated with all of API3’s data feeds on Ink, developers will have a built-in solution 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. 

Ink is an Ethereum OP Stack Layer 2 blockchain built by Kraken, designed to serve as the house of DeFi within the Superchain ecosystem. By combining the power of Ethereum scaling solutions with Kraken’s decade-long expertise in security and reliability, Ink accelerates the journey toward onchain financial sovereignty. Its mission is to simplify DeFi for everyone, acting as a bridge between visionary builders and users while enabling seamless capital flows across the Superchain and beyond.

With a builder-first approach, Ink provides developers with a world-class development environment, including financial support, rich documentation, and tailored onboarding. Featuring sub-second block times, low gas fees, EVM compatibility, and Kraken’s infrastructure to abstract complexity, Ink delivers the performance, security, and scalability required to shape the next chapter of DeFi.

Developers looking to utilize price feeds on Ink 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, 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 Ink. This solution makes it easy for dApps to quickly and easily migrate to Ink 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 Ink, 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 lending protocols, 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 Ink 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.
