Multi-Chain Monitoring & Alerts
Spy Signals
An on-chain monitoring and alert system polling contract activity across Polygon and Ethereum with redundant confirmation.
Spy Signals needed reliable alerts on contract write-functions across multiple chains, without overloading the system.
- 01
Built API endpoints for tracking contract addresses and write-function activity.
- 02
Ran alert polling as a separate worker process to keep the system light.
- 03
Added a secondary polling mechanism across Polygon and Ethereum via Infura as redundant confirmation.
A dual-chain monitoring system with redundant confirmation and timely alerts on contract activity.
Engineering depth in real-time data pipelines and reliable monitoring — directly transferable to operational dashboards and alerting.
