Chainlink Functions Sunset Notice
Chainlink Functions sunsets on June 30, 2026 (testnet: June 15, 2026).
Migrate to the Chainlink Runtime Environment (CRE), which provides all Functions functionality and more. Migrate your existing subscriptions before these dates to avoid service disruption.
Reduced Service Windows
To help users identify Functions subscriptions that are still active and prepare for the Functions sunset, we will temporarily reduce the Functions service during the following windows:
- June 18, 9:00 AM–1:00 PM EDT (4 hours)
- June 22, 6:00 AM–2:00 PM EDT (8 hours)
- June 24, 9:00 AM–June 25, 9:00 AM EDT (24 hours)
During these windows, existing Functions subscriptions may not execute as expected. These temporary service reductions are intended to help identify workloads that have not yet been migrated to CRE before the final sunset date.
To ensure uninterrupted operation, migrate your subscriptions to CRE before the applicable sunset date.
See the CLF to CRE migration guide for a full concept mapping and code examples.
