Witnet Oracle Docs

Multi-chain, secure and reliable data retrievals right from the outside world, made easy.

NextWhat is Witnet?

Last updated 5 months ago

Was this helpful?

The multichain decentralized oracle enables smart contracts to realize their true potential by giving them access to all sorts of valuable data sets, and by attesting and delivering that information securely thanks to its strong cryptoeconomic guarantees.

Witnet can power most DeFi primitives like price feeds, stablecoins, synthetics, etc., as well as acting as a reliable source of randomness for creating uniqueness in NFTs.

The Witnet oracle is currently available on Ethereum, Polygon, Avalanche, Celo, Harmony, Metis, Boba, Conflux, KCC and other blockchains ().
