Real-time blockchain data streams on every channel
One real-time firehose across 40+ chains — DEX trades, transfers and new tokens on EVM and Solana, decoded and ready. Stream it your way: binary gRPC in under 100ms, durable Kafka with replay, browser-ready WebSocket subscriptions, or straight into your cloud warehouse.
Pick your latency. Same data underneath.
Every channel reads the same decoded, cross-chain event stream — choose the transport that fits your job. gRPC for raw speed, Kafka for durability, WebSocket for zero infra, Cloud when the data should live in your warehouse.
Binary Protobuf firehose — the lowest-latency channel we ship. Built for snipers, MEV and HFT bots that react in milliseconds.
Enterprise-grade Protobuf streams with guaranteed delivery and offset replay — never drop an event, backfill on reconnect.
Browser-ready GraphQL subscriptions with server-side filtering and USD values out of the box. Zero infrastructure to run.
Stream straight into Snowflake, BigQuery, S3 or Azure as managed datashares — no consumer to operate, query where your data lives.
Every event type, across every chain.
One subscription spans the data that matters — trades, transfers, launches, balances, mempool and contract events — decoded into a typed schema and filterable by token, wallet, market or program.
Building a streaming stack off raw nodes is its own project.
Raw nodes give you undecoded firehose data and reconnect headaches across every chain. Bitquery hands you decoded events on the transport you want — one schema, 40+ chains, fully managed.
What teams ship on Data Streams.
Every one is a filter on the same firehose — subscribe on any channel and react the moment the event lands.
Trading & sniping bots
Stream decoded DEX trades and new token launches across EVM and Solana in milliseconds, and fire orders before the rest of the market reacts.

"We did a thorough search of the market for the best onchain data. Bitquery came out on top — and now powers all live prices across Nansen. We don't think of them as a vendor. They're a partner."
Bitquery does the hard work of parsing blockchain transaction data into a usable form so that we don't have to. We use their interface to diagnose issues with complex transactions and their analytics as a starting point for our own.
They proved they had the technology to deliver sophisticated data solutions. We extended our support through the Binance X fellowship — building an open-source library of visualization widgets on their blockchain data.
The complex raw data is available at different levels of detail and from different viewpoints — whether we need simple aggregated transfers or parameters for failed contract calls. The support is responsive, friendly and quick.
Partnering with Bitquery has been highly cost-effective — leveraging their established infrastructure rather than building our own let us rapidly expand our blockchain support and reach a much broader segment of on-chain users.
Bitquery's products are very intuitive and easy to use. We currently use their products to obtain DEX-related trading and liquidity information, which saves us the manpower and tedious technical details required to develop our own system. Their excellent technical team deserves special praise; they provide near-24/7 support and resolve issues quickly. I greatly appreciate their products and work ethic.
Bitquery provides the infrastructure we rely on every day. Fast, reliable, and comprehensive across the chains that matter to our business.
