Web3 Data Streaming Service
Turn blockchain events into structured, real-time data streams with millisecond-level updates
Chainstream’s Web3 Data Streaming Service delivers fast, reliable access to on-chain activity across major chains like Ethereum, Solana, BNB Chain, and Polygon.
Why Use Web3 Data Streaming?
Traditional APIs require constant polling and often miss short-lived events. With Chainstream, you get push-based access to real-time blockchain activity as it happens. Whether you’re building DeFi monitoring tools, automated trading bots, or alerting systems, streaming data provides the foundation for high-performance, event-driven infrastructure.
What It Delivers
Live Blockchain Events
Subscribe to a wide range of on-chain actions, including token swaps, wallet transfers, liquidity changes, NFT interactions, and smart contract executions. Every event is delivered with structured metadata for easier processing.
Cross-Chain Coverage
Track activity across multiple blockchain ecosystems through a single interface. Data is normalized, timestamped, and deduplicated to support multi-chain analytics and real-time decision-making.
Low-Latency Delivery
Our Kafka-based backend processes millions of messages per second, ensuring minimal lag between the block confirmation and event delivery. Expect sub-100ms push times for high-frequency networks like Solana.
Flexible Consumption Models
Stream data using Kafka, WebSocket, or cloud-forwarding options depending on your setup. Whether you’re building a local processor or feeding data into an analytics pipeline, you have full control over how events are consumed.
Who It’s For
DEX Aggregators
Track real-time swaps and pool changes to surface better pricing or detect MEV opportunities.
DeFi Protocols
React to on-chain triggers like deposits, liquidations, or oracle updates to drive automated contract behavior.
Security and Risk Tools
Build alerting systems that detect suspicious transfers, wallet activity spikes, or smart contract exploits the moment they happen.
Analytics Platforms
Capture high-volume transaction streams to power dashboards, TVL trackers, and token flow visualizations.
