# Supported Networks

Oracle Labs Chainlink nodes are free to use on any supported testnets.

They do not require whitelisting and are operated and monitored in the same way like our production nodes to enable a smooth development and testing process.

Currently we support following blockchain networks:

* Polygon Mainnet
* Ethereum Goerli (testnet)
* Polygon Mumbai (testnet)

Other mainnets and testnets can be supported on request.
