Deprecation of Chainlink Data Streams

Due to the rapid evolution of onchain ecosystems, Chainlink Data Streams feeds are regularly evaluated to ensure that network usage, cost efficiency, and long-term sustainability remain aligned with the needs of the ecosystem.

As part of this ongoing evaluation, Data Streams feeds without publicly known active users may be scheduled for deprecation. Doing so not only allows us to keep our Data Streams offering aligned with today's market landscape, but it also helps to reduce unnecessary costs incurred by Chainlink node operators. This process is part of a broader ecosystem initiative to maximize the adoption of the Chainlink network while optimizing for cost-efficiency and long-term economic sustainability.

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