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 co-located Ethereum node access for a local path to chain data.
Understanding BLAZED.sh’s Architecture
BLAZED.sh is optimized for Ethereum applications that require consistent low latency and predictable costs. Instead of calling a remote gateway across the public internet, your service runs on the same host as a fully synced Ethereum node and connects today over the node’s local WebSocket endpoint (ws://eth:8545).
