# Sunset of Blast Swapping Support (/docs/changelog/active-notifications/sunset-of-blast-swapping-support)

Posted: October 7, 2026 | Effective: October 28, 2026

We are sunsetting swapping support for the Blast network (chain id 81457) on October 28, 2026.

**What is changing?**

Starting October 28, 2026, Uniswap will no longer support swapping on Blast. Quote requests for Blast will return a 404 with `errorCode: UnsupportedChainError` (see [Troubleshooting Common Errors](/docs/trading/swapping-api/common-errors#404-no-quotes-available)).

**Why is this changing?**

The Blast network has announced their intention to shut down. We are ending support for swapping on Blast in line with their team.

**What do I need to do?**

If your integration requests quotes or swaps on Blast, stop those requests and move funds to an alternative supported chain before October 28, 2026.
