⚡Yellowstone gRPC

Our Yellowstone-compatible gRPC service is a faster way to access FluxRPC.

This isn't a rehash vibe-coded off a competitor's product. It's engineered from the ground up, to leverage the high performance of our FluxRPC streams.

That means lower latency — your application will receive an update as soon as an event happens on-chain.

Yellowstone support is included at no extra cost to our Developer, Business, and Pro plans. As always, you only pay for the bandwidth you use.

To start using Yellowstone, log in to your FluxRPC account. Select API Keys in the sidebar menu. Choose your network (Fogo or Solana) and if applicable, the server location closer to you. The correct URL to use to connect to Yellowstone will display below, with your API keys.
