For Solana Developers
Real-time blocks, transactions, and account data via gRPC. A cost-efficient drop-in replacement for Helius LaserStream — built by devs who ship production Solana infrastructure daily.
Data streaming is one of the biggest cost killers in blockchain projects — and the incumbents know it.
Every detail designed by builders who ship production Solana infrastructure every single day.
Stream blocks, transactions, and account data live as they hit the chain via high-performance gRPC.
Miss nothing. Solstream buffers 3,000 slots of historical data for instant replay on reconnect.
Resilient design handles disconnects transparently. Your stream picks up exactly where it left off.
Program log filters, signature subscriptions, token balance subscriptions and more.
V2The most seamless drop-in LaserStream alternative for vibe-coded and code-gen workflows.
On-premise servers with cloud failovers across US East and Central Europe for maximum availability.
Drop in, connect, stream. Engineered to feel instantly familiar to any Solana developer.
Whether you're building a DeFi protocol, MEV bot, or AI pipeline — Solstream's SDK means you're streaming real Solana data in a single afternoon.
// npm install @solstream/sdk import { SolstreamClient } from '@solstream/sdk'; const client = new SolstreamClient({ apiKey: process.env.SOLSTREAM_API_KEY, region: 'us-east', reconnect: true, }); const stream = await client.subscribeBlocks({ includeTransactions: true, commitment: 'confirmed', }); for await (const block of stream) { console.log(`Slot ${block.slot} · ${block.transactions.length} txs`); } // Migrating from Helius LaserStream? // Just swap the endpoint URL. Same gRPC interface.
Free for early access users and hackathon participants.
A deliberate, phased rollout — battle-tested by Solstice in production before reaching you.
Built for Solana developers who need reliable, cost-efficient data streaming without the enterprise markup.
