Yellowstone gRPC — Real-Time Solana Streaming

Stream every transaction, account update, slot, and block on Solana in real-time using Yellowstone gRPC. This is the foundation for any latency-sensitive Solana trading system — replacing REST polling with push-based streaming at ~5ms slot latency.

Why Yellowstone gRPC

Method Slot Latency (p90) Use Case
REST polling (getTransaction) ~150ms+ Historical lookups
WebSocket (onLogs) ~10ms Simple notifications
Yellowstone gRPC ~5ms Production trading systems

Yellowstone is a Geyser plugin that exposes Solana validator data over gRPC. Every major RPC provider runs it. You subscribe to filtered streams of transactions, account changes, slots, blocks, and entries — and the data pushes to you.
