About Tellor

Tellor is an immutable decentralized oracle protocol that incentivizes an open, permissionless network of data reporting and data validation, ensuring that data can be provided by anyone and checked by everyone.
Built for any data type, our network of reporters supports your basic spot prices, more sophisticated pricing specs (TWAP/VWAP), Snapshot Vote Results, or any custom data needs you have. If your data can be verified, Tellor can bring it on-chain.
