Frequently Asked Questions
Get clear answers on how our enterprise-grade event monitoring service works, from deployment to ongoing support.
Our service deploys a network of dedicated, high-availability listener nodes across supported blockchains (Ethereum, Polygon, Arbitrum, etc.). These nodes monitor on-chain events in real-time based on your smart contract addresses and event signatures. When a target event is detected, we securely relay the data to your backend via a webhook or Websocket connection, with optional message queuing for guaranteed delivery. We handle all the infrastructure complexity, including node health, RPC failover, and data parsing.
