One persistent connection streaming sequential updates

One connection, all updates

Stream accounts, transactions, slots, blocks, and entries over the full Yellowstone API. Subscribe, modify, or cancel without reconnecting.
Multiple inputs converging into one focused output stream

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.
Globe with network nodes representing regional proximity

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.
Parallel redundant paths converging into a single reliable connection

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.
Glowing arch bridging a gap in a stream of data blocks

Built-in backfill

Resume from any recent slot and backfill missed data automatically. No separate backfill pipeline, no gap-detection logic to maintain.
Waveform with glowing nodes representing live stream telemetry

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.

  • 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.

  • 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.

  • 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.

  • 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.

  • $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.

  • 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.

  • Generate an Alchemy gRPC endpoint from your Alchemy dashboard, point your Yellowstone client at it, and start streaming. No plan upgrade required.
