Contract Event Pusher
A high-performance backend service that listens to on-chain events from any EVM-compatible smart contract and delivers real-time notifications to your application.
The Challenge
Most dApps have to constantly poll blockchains to detect state changes, which is expensive, slow, unreliable, and complex to manage with chain reorganizations.
Core Offerings
A reliable push-notification engine for EVM smart contract events.
Contract Registration
Clients register contract addresses, target networks, and ABI fragments through a REST API.
Real-Time Event Listening
Persistent connections to Ethereum node providers listen for events, decode logs, and verify payloads.
Reliable Delivery
Events are queued in Redis and delivered with exponential backoff retry logic and delivery confirmations.
Reorg Handling
Chain reorganizations are automatically detected and replacement events are seamlessly re-delivered.
Technical Architecture
The Impact
"Adopted by teams building NFT marketplaces and DeFi dashboards to react to blockchain state changes without managing their own complex event indexing infrastructure."
