# Sonic Blaze Testnet Deprecation Notice

> Important notice regarding the deprecation of the Sonic Blaze testnet and how to migrate to Sonic Testnet

> For the complete documentation index, see [llms.txt](/docs/llms.txt).

## ⚠️ Deprecation Notice

**Alchemy will fully deprecate support for the Sonic Blaze testnet on June 12, 2026.** After this date, requests to Sonic Blaze endpoints (`sonic-blaze`) will no longer be supported.

Sonic Blaze is being deprecated because it was [sunset by Sonic Labs on May 1, 2026](https://x.com/SonicLabs/status/2034664628903629171). Sonic Mainnet and Sonic Testnet remain fully supported.

## Migrate to Sonic Testnet

Please move your traffic to **Sonic Testnet** (Sonic's current testnet) before June 12, 2026:

1. Enable **Sonic Testnet** for your app on the [Endpoints page in the Dashboard](https://dashboard.alchemy.com/).
2. Update your endpoint URL from `sonic-blaze` to `sonic-testnet` in your codebase:

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

No other changes are required. See the [Sonic API Quickstart](/docs/reference/sonic-api-quickstart) to get started.

## Need help?
