Sonic Blaze Testnet Deprecation Notice

Alchemy support for the Sonic Blaze testnet ended on June 12, 2026. Requests to Sonic Blaze endpoints (sonic-blaze) are no longer supported.

Sonic Blaze was deprecated because it was sunset by Sonic Labs on May 1, 2026. Sonic Mainnet and Sonic Testnet remain fully supported.

Move your traffic to Sonic Testnet (Sonic's current testnet):

Enable Sonic Testnet for your app on the Endpoints page in the Dashboard.
Update your endpoint URL from sonic-blaze to sonic-testnet in your codebase:

https://sonic-testnet.g.alchemy.com/v2/YOUR_ALCHEMY_API_KEY

No other changes are required. See the Sonic API Quickstart to get started.

If you have any questions or need assistance migrating, contact us at support@alchemy.com or open a ticket in the Alchemy Dashboard.
