Circle Internet Financial has introduced Event Monitoring for its Smart Contract Platform, enabling developers to subscribe to events on Ethereum Virtual Machine (EVM) blockchains and receive real-time notifications via webhooks. This feature allows developers to track activities and take programmatic actions based on events emitted by smart contracts, enhancing the responsiveness and security of on-chain applications. Event Monitoring facilitates the monitoring of transactions and state changes, and offers immediate notifications for unusual activities, providing developers with the insights needed to maintain secure and dynamic applications. It supports various use cases, such as tracking cross-chain USDC transfers, sending instant notifications, updating real-time app portfolios, and detecting unusual activities. Developers can easily set up event notifications through the Circle Console and integrate on-chain activities with off-chain actions using Circle's API.
