One event stream, everything you build on top

Everything the platform gives you
The delivery infrastructure behind production trading systems, exposed as webhooks.
- HMAC-signed delivery
- Every payload is signed with your subscription secret so you can verify authenticity in one line.
- At-least-once delivery
- Failed deliveries retry with exponential backoff until they land, so no event is silently dropped.
- Granular filters
- Scope by chain, wallet, market, tag, or category, with thresholds set per subscription server-side.
- Sub-second delivery
- Events fire the moment they land onchain. No polling intervals, no cache windows, no waiting.
- Unified multi-chain coverage
- One event model across every chain Struct indexes, EVM and SVM, with no per-network integration.
- No infra to run
- No queues, workers, or indexers to operate. Register an endpoint and Struct handles delivery.
