Event types from whale trades to metric thresholds.

50 ms

Latency from onchain event to your endpoint.

Every trigger your bot needs, pushed to you

Subscribe to the events that matter, we deliver them signed. Your code just reacts.

Track the wallets that matter

Whale trades, first trades from tracked wallets, and per-wallet PnL crossings, pushed as they happen.

Thresholds without the math

Set crossings on volume, liquidity, open interest, and transaction counts. We watch, you get the event.

Catch markets as they launch

New markets and tokens the moment they appear, plus every status change through their lifecycle.

Straight into your automation

Wire events into trading bots, Telegram and Discord alerts, and backend jobs. No queue in between.

Delivery you can build a product on

The same event stream behind Struct's own Scanner Bot and Alerts Bot.

Sub-second delivery: Events fire the moment they land onchain. No polling intervals, no cache windows, no waiting.
HMAC-signed payloads: Every delivery is signed with your subscription secret, so you verify authenticity in one line.
At-least-once delivery: Failed deliveries retry with exponential backoff until they land. No event is silently dropped.
Granular filters: Scope by chain, wallet, market, tag, or category, with thresholds enforced server-side.
Every chain, one feed: Solana, Ethereum, Base, BSC, and Polygon, behind a single subscription.
Nothing to run: No queues, workers, or indexers to operate. Register an endpoint and Struct handles delivery.

What it takes to go from event to alert

Typed events in, context on demand, working reference bots to fork, and a team on call while you ship.

20+ event types

Whale trades, price and volume moves, market and token lifecycle, and metric thresholds, all from one subscription.

Open-source reference bots

Struct's Scanner Bot and Alerts Bot run on this stream. Fork them or read exactly how they consume events.

TypeScript SDK

Typed payloads for every event type, so your handlers stay honest as you add subscriptions.

REST and websockets alongside

When an event fires, pull the market, wallet, or candles behind it from the same API and schema.

Backfilled history

Complete historical data through Managed Backfill when your bot needs context beyond the live stream.

Your second backend team

24/7 support on calls, Telegram, and Slack while you wire it up, not just after something breaks.
