Api3 is live on Katana

Api3 oracles are now live on Katana—fully permissionless, instantly accessible, and available through the Api3 Market. These onchain feeds are powered by first-party oracle nodes run directly by the data providers, eliminating middlemen and ensuring source-level integrity.

What sets this deployment apart is that every feed on Katana comes with OEV recapture built in, through integration with Api3’s OEV Network. When valuable actions—such as liquidations—are possible within a protocol, searchers can acquire privileged access to the latest price data by winning an onchain auction. This allows them to execute the action before the update becomes publicly available. The auction proceeds are then returned to the dApp that generated the opportunity.

This turns previously leaked value into a native revenue stream, improving protocol performance without requiring any changes to application logic.

Why Katana

Katana is a DeFi-first Layer 2 chain incubated by Polygon Labs and GSR, built to fix what’s broken in DeFi: fragmented liquidity, short-lived incentives, and value extraction from users. Instead of spreading assets thin across competing apps, Katana concentrates liquidity into a focused set of protocols and cycles revenue back to the network via chain-owned liquidity (CoL).

It’s the first Agglayer CDK chain to go live, combining deep liquidity, productive assets, and sustainable yield into a single system. Katana isn’t just another general-purpose chain—it’s a purpose-built environment where users, apps, and the network grow together.

That mission aligns directly with ours: helping dApps keep what’s theirs by providing oracle infrastructure that lets them recapture the value they create.

What This Means for Developers

Deploying on Katana now means your dApp has access to oracles that don’t just report prices—they capture value. With OEV recapture built in, every price update can generate protocol-native revenue without requiring any changes to your user flow or protocol logic. It’s as simple as using the right oracle.

Feeds are maintained directly onchain by first-party oracles, so you don’t need to run infrastructure or manage offchain dependencies. Just read secure, verifiable data, concentrate on growing your dApp—and get paid.

Whether you’re building lending markets, derivatives, or anything that depends on fresh, reliable data—you now get that data and keep the value it unlocks.
