Oracles

API3

API3 is building secure first-party oracles for Base.

API3 is live with:

  • dAPIs: First-party aggregated data feeds sourced directly from the data providers.
  • Airnode: The first-party serverless Oracle solution to bring any REST API onchain.
  • QRNG: Quantum Random Number Generator for verifiable quantum RNG onchain.

Supported Networks

  • Base Mainnet
  • Base Goerli (Testnet)

Chainlink

Chainlink provides a number of price feeds for Base.

See this guide to learn how to use the Chainlink feeds.

:::info

To use Chainlink datafeeds, you may need LINK token.

Supra

Supra provides VRF and decentralized oracle price feeds that can be used for onchain and offchain use-cases such as spot and perpetual DEXes, lending protocols, and payments protocols. Supra’s oracle chain and consensus algorithm makes it one of the fastest-to-finality oracle providers, with layer-1 security guarantees. The pull oracle has a sub-second response time. Aside from speed and security, Supra’s rotating node architecture gathers data from 40+ data sources and applies a robust calculation methodology to get the most accurate value. The node provenance on the data dashboard also provides a fully transparent historical audit trail. Supra’s Distributed Oracle Agreement (DORA) paper was accepted into ICDCS 2023, the oldest distributed systems conference.

Visit the Supra documentation to learn more about integrating Supra's oracle and VRF into your Base project.
