Real-time blockchain events & webhooks

Stream on-chain events
to your backend in real time

EventStream captures blockchain activity as it happens and delivers it to your backend via reliable, zero-loss webhooks and subscriptions. Power alerts, payments, analytics and monitoring with low-latency, multi-chain event feeds.

Start with EventStream

EventStream

Real-time blockchain events delivered directly to your backend. Subscribe to transfers, contract events, blocks and more — across multiple networks — with guaranteed, ordered, zero-loss delivery. Ideal for mission-critical Web3 apps that cannot afford to miss a single on-chain event.

Webhook Delivery

Receive blockchain events as signed HTTP webhooks with automatic retries, backoff and idempotency. Integrate with any backend stack without managing sockets or queues yourself.

Real-time Subscriptions

Create fine-grained subscriptions by address, topic, method signature or contract. Stream only the events you need and keep noise and infrastructure costs under control.

Monitoring & Alerts

Trigger instant alerts on critical events — large transfers, protocol actions, wallet activity or risk signals. Keep your operations, users and compliance tools in sync with the chain in real time.

Replay & Recovery

Safely replay missed events for a chosen block range or time window. Recover from incidents without gaps in your data and keep downstream systems fully consistent.

Supported Networks & events

EventStream works across 70+ networks, covering transfers, contract logs, token events and block activity from a single integration.
Track payments, DeFi positions and protocol events in real time on Ethereum, BNB Chain, Solana, Tron, TON, Bitcoin and many more.

learn more about EventStream

EventStream is a real-time blockchain events service that streams transfers, contract events, blocks and other on-chain activity to your backend using webhooks or streaming protocols. You subscribe once and receive fresh data without manual polling.

RPC Gateway and Unified API are pull-based: your app asks for data when needed. EventStream is push-based: it continuously sends events to your backend the moment they appear on-chain. They work best together — Unified API for historical queries and EventStream for live updates.

You can subscribe to native transfers, token transfers, contract logs, method calls, new blocks and address activity. Filters let you narrow streams by address, topic, token or network to receive only relevant events.

EventStream sends HTTP POST requests to your webhook URL with structured JSON payloads. Each request is signed so you can verify authenticity, and you can restrict delivery by IP or network. Retries and idempotency help avoid duplicates and missed events.

EventStream is designed for zero-loss delivery with retries, ordering within a stream and idempotent payloads. If your endpoint is temporarily unavailable, events are retried and can be replayed over a selected range.

Yes. EventStream supports replaying events from a specific block height, timestamp or subscription checkpoint. This allows you to safely recover after outages and keep external systems consistent.

Latency depends on the network, but events are usually available within a few hundred milliseconds after they appear on-chain. For many chains, updates are streamed in near real time.

EventStream uses usage-based pricing based on the number of delivered events and active subscriptions. You can start with a free tier for development and scale to higher volumes as your product grows.

Set up a webhook endpoint, request an API key and create your first subscription by network, address or event type. Use our examples to test delivery and then plug EventStream into your production flows.

Yes. You can configure rate limits, batching and backoff parameters for your webhooks. This prevents overloading your backend during network spikes or high on-chain activity.

Enterprise customers can access dedicated infrastructure, custom SLAs and private endpoints for critical workloads such as exchanges, payment systems or large-scale analytics platforms.

Absolutely. Unified API provides historical and analytical data, EventStream powers real-time event delivery, and AML Intelligence adds risk and compliance context. Together they form a complete Web3 data and monitoring platform.
