⛓️Supported chains

A complete list of the Wit/Oracle counter-factual contracts deployed by the Witnet Foundation on more than 50 different chains.

The Wit/Oracle EVM Bridging framework enables your smart contracts to:

• Pull parameterized custom data from the real world.

• Read latest updates on the subsidized price feeds by the Witnet Foundation.

• Pull fresh price updates at your own device.

• Pull and fetch unbiased and unmalleable randomness from the Wit/Oracle blockchain.

Data requests to the Wit/Oracle get paid in native EVM currency:

• No ERC-20 tokens involved.

• No need to hold $WIT coins, either.

• No subscriptions or KYC workflows required.

• No need to run your own off-chain infrastructure.

The Wit/Oracle solution works just right out of the box !

For every supported chain, external links to docs, market places, bridges, wallets and faucets (in the case of testnets) are also provided for your own convenience.
