Self-managed Data Feeds are now supported, allowing chains and operators to publish data onchain. See Self-Managed Feeds for more information, or contact the Data Feeds team at chainlinkdatafeeds@smartcontract.com for details regarding deployment.
Note: Chainlink Labs does not manage the onchain publication path, monitoring, or service levels for self-managed feeds and does not list their proxy addresses in official documentation; the chain or its operator is responsible for running the workflow, maintaining contracts, and supporting integrators.
