Sunset of Blast Support
Posted: June 29, 2026
We are sunsetting support for the Blast network (chain id 81457) in Uniswap bridging and cross-chain flows.
What is changing?
Blast is being removed from bridging and cross-chain (chained actions) flows in the Uniswap apps and API. Blast is also being removed from the supported chains and deployment references in these docs.
Why is this changing?
Demand for Blast has decreased significantly, so we are ending support for these flows.
What do I need to do?
If your integration uses Blast for bridging or cross-chain (chained actions), move to a supported chain. The current list is available at Supported Chains.
