Welcome to Yellowstone gRPC

Yellowstone Dragon’s Mouth is a high-performance gRPC interface for Solana, built around the Geyser plugin framework. It provides real-time streaming of blockchain data including accounts, transactions, blocks, and slots through a standardized gRPC API.

​
What is Geyser?

Geyser is Solana’s plugin interface that allows validators to stream account updates, transaction data, and block information in real-time. Yellowstone gRPC implements a Geyser plugin that exposes this data through a gRPC API, making it accessible to external applications.

​
Use Cases

Monitor specific Solana accounts for balance changes, data updates, or ownership transfers. Perfect for tracking token accounts, program state, or NFT collections.
Build custom transaction indexers that process Solana transactions in real-time. Filter by program IDs, account involvement, or transaction signatures.
Power block explorers and analytics platforms with comprehensive block data including all transactions, account updates, and metadata.
Stream price feeds, liquidity pool updates, and trading activity for decentralized finance applications.
Track NFT mints, transfers, and marketplace activity across Solana NFT programs.

​
How It Works

  1. The Yellowstone gRPC plugin loads into a Solana validator via the Geyser interface
  2. Your application connects to the gRPC server and sends subscription requests with filters
  3. The plugin streams real-time updates matching your filters
  4. Your application processes the updates as they arrive
