**Self-managed feeds** are Data Feeds where values are written onchain by a **third party** (typically the chain or its designated operator), not by Chainlink node operators publishing through Chainlink Labs–managed oracle infrastructure.

At a high level, a [Chainlink Runtime Environment (CRE)](/cre) workflow reads from [Chainlink Data Streams](/data-streams) and writes updates to a proxy contract so consumers can read answers using the same familiar Data Feeds interfaces. **Chainlink Labs does not manage the onchain publication path, monitoring, or service levels** for these deployments. The chain (or its operator) is responsible for running the workflow, maintaining contracts, and supporting integrators.

**Contract addresses for self-managed feeds are not listed in Chainlink public documentation.** Obtain deployed proxy addresses directly from the chain or its designated operator.

## Responsibilities & guarantees

### Data quality

Data for assets are delivered through **[Chainlink Data Streams](/data-streams)**. Data Streams provides the offchain data for the self-managed feeds; however, it is the third party’s obligation to read, transform, or write the correct values onchain on schedule.

### Monitoring & service levels

**These onchain feeds are not managed or monitored by Chainlink Labs.**

Specifically:

- Chainlink Labs does **not** provide monitoring for:
  - Heartbeat compliance
  - Deviation compliance
  - End-to-end latency of writing prices onchain
  - Whether the correct data was written onchain
- No service level agreements (SLAs) are provided for self-managed feed publication.
- No onchain monitoring specific to these feeds is provided by Chainlink Labs.

### Feed visibility

- Proxy addresses for self-managed feeds **do not appear** on official Chainlink public documentation sites (including feed address catalogs).
- Integrators must obtain deployed contract addresses **directly from the operators** of the self-managed feeds on each chain.
