API3 Launches Verifiable, Decentralized Data Feeds on Linea

We are excited to announce that API3’s managed dAPIs are available on Linea. Developers on Linea can now access over 120 verifiable, decentralized data feeds powered by first-party oracle nodes, which are operated directly by the data providers.

Linea is a developer-centric zkEVM rollup, designed as an innovative Layer 2 solution for scaling Ethereum dApps. Developed by Consensys and natively integrated with MetaMask, it combines zero-knowledge proofs with full Ethereum Virtual Machine (EVM) compatibility. This allows developers to seamlessly create or migrate scalable dApps without code alterations. DeFi applications are choosing Linea for its fast finality, capital efficient bridge, and inherited Ethereum security. NFTs, gaming, and social apps benefit from the zkEVMs EVM Equivalence, low gas fees, high throughput, and low latency.

“We’re thrilled to team up with API3. This collaboration brings high-quality, verifiable data feeds to Linea, making us an even more compelling choice for DeFi developers. With API3’s trusted oracles, we’re not just streamlining data costs — we’re actively enhancing the robustness of DeFi applications built on our platform, “ said Declan Fox, Global Product Lead for Linea.

Developers looking to utilize managed dAPIs on Linea can visit the API3 Market. The API3 Market provides an easy way to browse, access, and manage a wide variety of data feeds, including crypto, forex, equities, and commodities.

Managed dAPIs are changing the way dApps use real-time market data. Delivered as a managed service, they abstract away operational factors like gas management, maintenance, and monitoring. Developers looking to utilize managed dAPIs simply need to read the associated data feed.

“Our collaboration with Linea underscores our commitment to help scale DeFi. By integrating managed dAPIs into Linea’s zkEVM, developers can now access a wide range of real-world data in a direct, verifiable way. By enabling developers to simply read data that is maintained onchain, we’re not only ensuring dApps can easily migrate and scale, but also staying true to the core blockchain values of transparency and verifiability,” said Ugur Mersinlioglu, Product Lead for API3.

Simply Read Verifiable, Decentralized Data to Power dApps

API3’s first-party oracle architecture maintains data on-chain directly from the data providers. This decentralized and verifiable design eliminates rent-seeking middlemen and offers a more secure and efficient method of bringing data directly on-chain.

One of the key benefits of the managed service 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 directly maintained on-chain. This solution simplifies the way data is maintained and also facilitates dApps quickly and easily migrating to Linea 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 on-chain 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 managed dAPIs on Linea, developers gain direct access to an assortment of real-world data, including crypto, forex, equities, and commodities straight from the source.

Building the Future of DeFi

As technological innovations continue to improve the core infrastructure necessary for scaling DeFi to the broader world, the collaborative approach between Linea and API3 represents the crucial role oracles have to play. The next generation of blockchain oracles should provide improved security and transparency with first-party oracle solutions.

Getting Started with dAPIs

Aligning with Linea’s mission to facilitate seamless dApp creation or migration without altering code, API3’s managed dAPIs provide a scalable and turnkey solution for developers. For those new to dAPIs, a developer Getting Started with dAPIs Video is available to guide you through the API3 Market.
