Solana gRPC Streaming - Yellowstone-Compatible | Alchemy
Ultra-fast Solana gRPC streaming
The fastest and most reliable Yellowstone-compatible gRPC built for the traders, indexers, and MEV teams who can't afford a missed trade or incomplete data.
Powering the best
Everything Solana streaming should be
Engineered to never miss a slot, built to drop into your stack, priced for any volume. Production-grade streaming for the most demanding Solana workloads.
No single point of failure
Alchemy gRPC pulls from multiple upstream nodes in parallel and always delivers the fastest data. One slow node never slows your app.
Drop-in Yellowstone compatibility
Keep the Yellowstone libraries you already use in Rust, TypeScript, Go, or anything that compiles a .proto. Migration is just a URL change.
Pay only for what you stream
$75 per TB. No plan prerequisite, no monthly minimum. Bursty MEV bots and high-volume indexers pay the same rate.
No gaps on reconnect
Brief disconnects and client restarts shouldn't cost you data. Alchemy gRPC backfills automatically when you reconnect. No missed slots.

One connection, all updates
Stream accounts, transactions, slots, blocks, and entries over the full Yellowstone API. Subscribe, modify, or cancel without reconnecting.
Stream only what matters
Filter by account, program, owner, or signature, and slice account data by offset. Your stream carries what your app needs, nothing more.
Close to your workload
Terminate in US East, US West, EU Central, or Asia-Pacific. Traffic stays close to your backend and the validators you care about.
Reliability at every layer
Every subscription is fanned across multiple upstream nodes. Failures, GC pauses, or slot lag on any single node never surface in your stream.
Built-in backfill
Resume from any recent slot and backfill missed data automatically. No separate backfill pipeline, no gap-detection logic to maintain.
Visible from day one
Prometheus-compatible metrics and per-stream telemetry. See stream health, throughput, and latency right in the Alchemy dashboard.
Frequently asked questions
Everything you need to know about Yellowstone-compatible streaming on Alchemy.
What is Alchemy gRPC?
A real-time Solana data streaming service over gRPC. Alchemy gRPC delivers account, transaction, slot, block, and entry updates to your backend with low latency and high reliability. Yellowstone-compatible, so it drops into the client libraries your team already uses.Who is Alchemy gRPC for?
Teams building latency-sensitive Solana products: traders, MEV searchers, liquidation bots, DEXes, wallets, indexers, and analytics platforms. Anyone whose product depends on fresh, complete on-chain data.How do I migrate from another Yellowstone provider?
Swap your endpoint URL and authentication. Your existing Yellowstone client code keeps working in Rust, TypeScript, Go, Python, or anything that compiles a .proto. Most teams migrate in under an hour.How does the multi-node architecture work?
Every subscription fans out across multiple upstream Solana nodes. The fastest healthy node always wins each update, so a single node hitting a GC pause, falling behind on slots, or restarting never reaches your stream. Read how we built fault-tolerant Solana gRPC streaming for the full architecture, including shred ingestion, Richat aggregation, and replay on reconnect.What does it cost?
$75 per terabyte, billed by usage. No plan prerequisite, no minimum monthly commit, no separate add-on to unlock streaming. You pay for the bytes you stream.How is this different from Alchemy’s RPC?
RPC is request-response: you ask, Alchemy answers. gRPC is streaming: Alchemy pushes new data to you the moment it lands on-chain. They're complementary: most teams use both, on the same Alchemy account.How do I get started?
Generate an Alchemy gRPC endpoint from your Alchemy dashboard, point your Yellowstone client at it, and start streaming. No plan upgrade required.
