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.

Unlocking the Blockchain: A Beginner’s Guide to Ethereum Nodes

Ethereum is a cornerstone of the blockchain revolution, driving decentralized applications and smart contracts that reshape our digital world. But what powers this vibrant network? Ethereum nodes—the critical infrastructure ensuring security, validating transactions, and enabling seamless interactions both on and off the blockchain. In this beginner-friendly guide, we’ll explore what Ethereum nodes are, their vital role in the network, and their importance for off-chain software via RPC. Whether you’re a crypto newbie, aspiring developer, or blockchain enthusiast, this post will empower you to navigate Ethereum with confidence.

Welcome Back to Arbitrage Basics

In our previous post on triangular arbitrage, we explored the fundamentals of 3-pair arbitrage opportunities. Today, we’re taking a significant leap forward by applying graph theory to discover arbitrage opportunities across any number of trading pairs. This approach transforms arbitrage detection from manual triangle checking into a systematic algorithmic problem.

By modeling trading pairs as a weighted directed graph, we can use classical algorithms like Bellman-Ford to detect negative cycles - mathematical representations of profitable arbitrage loops.

Welcome to Arbitrage Basics

In this little blog post series we want to educate you about the math, finance and programming aspects of arbitrage trading. In today’s episode we will explain some basics and show you how you can get started writing your own arbitrage trading scripts in JS. Obviously this wont generate any real profits, but knowing the basics is important to understand how the ones that do work.
