First off, thank you for being part of the BlastAPI community. We know you’ve put time and trust into building here, and we don’t take that lightly.

Since the Blast + Alchemy acquisition, our mission has been to give you access to the strongest possible platform to build, scale, and innovate onchain. To deliver on that promise, we’re excited to welcome you to Alchemy — the complete developer platform trusted by millions of builders across 60+ chains.

That said, the BlastAPI platform will be discontinued on October 31, 2025. After this date, Blast products will no longer be available, and projects still pointing to Blast endpoints will stop working.

👉 To keep your apps running past Oct 31, 2025, migrate to Alchemy. You’ll avoid disruptions — and unlock better performance, stronger reliability, and unlimited scalability.

Why Move to Alchemy?

We know switching platforms takes effort. That’s why Alchemy is built to make your apps stronger and your developer experience easier:

  • Ultra-low latency to deliver seamless user experiences
  • Best-in-class uptime and reliability you can count on
  • Infinite scalability to grow with your users
  • High-performance RPC nodes, advanced APIs and Smart Wallets
  • An intuitive dashboard and developer-friendly tooling

All of this is powered by Cortex, our blockchain engine designed to supercharge every app with speed, scale, and reliability.

Migration Timeline

  • Now → Oct 31, 2025: Migrate your projects to Alchemy to avoid service disruptions.
  • Nov 1, 2025: BlastAPI will no longer be supported.

👉 Get started with Alchemy here with 4 simple steps:

  1. Create an account → Sign up on Alchemy.
  2. Configure your APIs → Generate keys and set up endpoints in the dashboard.
  3. Migrate your applications → Update code to use Alchemy RPC URLs.
  4. Verify and deploy → Test and launch with Alchemy’s support + docs.

👉 Already using Alchemy? Please migrate your BlastAPI traffic as soon as possible.

We know migrations can be a big lift, but you don’t have to do it alone. If you have any concerns or need immediate support, reply to this email or visit our help center.

We’re excited about what you’ll build next on Alchemy and are confident this change will amplify your impact in the space.

Happy building, The BlastAPI team (now part of the AlchemyFam)
