Chainlink is a DeFi oracle that gives Ethereum-based smart contracts access to real-world data and off-chain computation. Their products include data feeds, Verifiable Random Numbers (VRF), calling external APIs, and automated contracts. The protocol is meant to be able to verify whether the parameters of a smart contract with real-world data are independent of stakeholders.

Band Protocol aggregates and connects real-world data and APIs to smart contracts.
Chronicle builds scalable, cost-efficient, decentralized oracles to overcome on-chain data limitations.
DIA is a multi-chain, end-to-end, open-source data and oracle platform for Web3.
Hyper Oracle is a programmable zkOracle protocol.
Midpoint is a platform for building oracles, data bridges, and off-chain storage.
