Building Real-Time Ethereum Event Notifications with BLAZED.sh

When building applications that need to respond to blockchain events in real-time, the choice of infrastructure can make or break your application’s performance and cost efficiency. This is particularly true for applications that use event filters returning large datasets - liquidation monitors, DEX aggregators, or cross-chain bridges that track thousands of events per block.

In this tutorial, we’ll create a webhook service that monitors specific Ethereum events and sends instant notifications to configured URLs. Whether you’re tracking token transfers, monitoring DeFi protocols, or building trading bots, BLAZED.sh provides the low-latency infrastructure and cost-effective pricing needed for production applications.
