Chainlink

Chainlink private feeds provide secure, reliable, and tamper-proof price data for your smart contracts.

Chronicle

Chronicle offers cost-efficient, scalable, decentralized, and verifiable Oracles for your smart contracts. For an overview of the different Oracles, please check the dashboard.

DIA

DIA delivers verifiable data feeds for 20,000+ assets across all major asset classes. It sources raw trade data directly from primary markets and computes it onchain. Check out the DIA docs to configure a feed for your use case.

Gelato

Gelato provides access to Verifiable Random Functions (VRF) on ZKsync. VRFs are cryptographic primitives that generate pseudorandom numbers in a way that is provably secure and verifiable. A VRF allows a holder of a private key to produce a random number along with a proof that the number was generated legitimately (making it publically verifiable). More information, including how to use VRFs in your dApp, can be found in the Gelato docs.

Pyth

Pythnet price feeds use a "pull" price update model, where users are responsible for posting price updates on-chain when needed. Checkout the usage guide to get started today!

RedStone

RedStone delivers frequently updated, reliable, and diverse data feeds for your dApp and smart contracts. Check out all the price feeds available to ZKsync Era and get started with the provided usage guide.
