Deprecation of Chainlink Data Feeds

The smart contract ecosystem is constantly evolving. As a result, Data Feeds within the Chainlink ecosystem are continuously evaluated for their usage and economic viability across all the blockchains and layer-2 networks they are deployed on.

Data Feeds with low or no usage or feeds that do not have a viable path to economic sustainability may be scheduled for deprecation. Doing so helps preserve blockchains as public goods by optimizing blockspace usage. It also helps to reduce unnecessary costs incurred by Chainlink node operators. This process is part of a broader ecosystem shift towards Chainlink Economics 2.0, designed to maximize the adoption of the Chainlink protocol while optimizing for cost-efficiency and long-term economic sustainability. Over time, new Data Feeds may be launched or relocated to alternative blockchains/layer-2s that better reflect current user demand.

For status updates regarding Data Feeds, users should join the official Chainlink Discord and subscribe to the data-feeds-user-notifications channel.

Users with additional questions are encouraged to reach out here.

A list of data feeds designated for deprecation along with their corresponding shutdown date can be found below. Please be advised that we will cease data quality monitoring for feeds designated for deprecation two weeks prior to the date of deprecation.
