Building Real-Time Ethereum Event Notifications with BLAZED.sh

Applications that react to blockchain events in real-time need low-latency infrastructure, especially when dealing with event filters that return large datasets (liquidation monitors, DEX aggregators, cross-chain bridges).

In this tutorial, we’ll build a webhook service that monitors Ethereum events and sends notifications to configured URLs, using BLAZED.sh’s IPC socket access for minimal latency.

Understanding BLAZED.sh’s Architecture

BLAZED.sh is optimized for Ethereum applications that require consistent low latency and predictable costs. While many providers offer WebSocket connections, BLAZED.sh provides exclusive IPC socket access (at /tmp/sockets/rpc_proxy.sock), eliminating network overhead entirely. This architectural choice ensures the lowest possible latency between your application and the Ethereum node.
