<Aside type="note" title="Contact us">
3916+
Chains and operators interested in deploying self-managed feeds can reach the Data Feeds team at

**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.
3921+
3922+
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.
3923+
3924+
As of March 2026, **[Jovay](https://jovay.io/)** and **[Pharos](https://www.pharos.xyz/)** offer self-managed feed deployments. **Contract addresses for these feeds are not listed in Chainlink public documentation**; obtain deployed proxy addresses directly from those networks or their operators:

## Responsibilities & guarantees
3930+
3931+
### Data quality
3932+
3933+
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.
3934+
3935+
### Monitoring & service levels
3936+
3937+
**These onchain feeds are not managed or monitored by Chainlink Labs.**
3938+
3939+
Specifically:
3940+
3941+
- Chainlink Labs does **not** provide monitoring for:
3942+
- Heartbeat compliance
3943+
- Deviation compliance
3944+
- End-to-end latency of writing prices onchain
3945+
- Whether the correct data was written onchain
3946+
- No service level agreements (SLAs) are provided for self-managed feed publication.
3947+
- No onchain monitoring specific to these feeds is provided by Chainlink Labs.
3948+
3949+
### Feed visibility
3950+
3951+
- Proxy addresses for self-managed feeds **do not appear** on official Chainlink public documentation sites (including feed address catalogs).
3952+
- Integrators must obtain deployed contract addresses **directly from the operators** of the self-managed feeds on each chain.
