## Description

Discover how to build effective AI Agents on Ethereum (or any chain) without over-engineered frameworks! Kirill Balakhonov (Nethermind) shares composable patterns—like simple prompt chaining, routing, evaluator-optimizer loops, and minimal autonomous loops—that deliver real results for agentic applications.

Learn why starting small and combining well-defined building blocks often yields more reliable, debuggable AI Agents than large “all-in-one” frameworks. Explore real-world examples (like code review, translation workflows, dynamic orchestration) that demonstrate how to harness LLMs efficiently. If you’re looking to streamline AI-driven dApps, this talk is a must-watch!
