The fastest way to consume Solana data. Yellowstone-compatible gRPC with Protocol Buffers — 10x more efficient than JSON-RPC. Stream accounts, transactions, slots, and blocks with fine-grained filters. Built for indexers, HFT systems, MEV bots, and anyone who needs every byte as fast as possible.
Start building on Solana in seconds
gRPC is a binary streaming protocol that delivers Solana blockchain data with the lowest possible overhead. Unlike JSON-RPC which serializes everything as text, gRPC uses Protocol Buffers — a compact binary format that's faster to serialize, smaller on the wire, and type-safe. Yellowstone is the Solana ecosystem's standard gRPC interface, and NoLimitNodes is fully compatible.
Protocol Buffers serialize data 10x smaller and faster than JSON — less bandwidth, less CPU, more throughput
Subscribe to accounts, transactions, slots, and blocks on a single connection with server-side filtering
Drop-in compatible with the Yellowstone/Geyser ecosystem — existing SDKs and tooling just work
gRPC over TLS · authenticate with x-api-key metadata · Yellowstone-compatible
Lowest possible latency for trade execution — binary protocol eliminates JSON parsing overhead entirely
Stream every transaction and account update for indexing services, explorers, and analytics backends
Monitor mempool and block data for liquidation, arbitrage, and sandwich opportunities at wire speed
Process millions of events per second for live dashboards, alerting systems, and anomaly detection
Track specific program accounts with fine-grained filters — only receive the data you care about
