# 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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
