Hedera Workshop EVM, SDKs, and AI Agents I Ed Marquez

Thu, Oct 2, 2025, 12:00 AM

Ed Marquez, Head of Developer Relations at Hedera, leads a technical workshop on building decentralized applications using Hedera’s SDKs, EVM compatibility, and AI agents. He explains Hedera’s technology stack, including consensus nodes, mirror nodes, and native services like the Consensus Service (HCS) and Token Service, which enable developers to create fungible and non-fungible tokens without smart contracts. Ed demonstrates using the Hedera Playground for rapid prototyping, showing how to create accounts, tokens, and perform token airdrops with JavaScript SDK. He highlights EVM compatibility, allowing Solidity smart contracts and familiar tools like Hardhat and Foundry. The Hedera Agent Kit SDK is introduced for building AI agents that interact with the network, automate tasks, and integrate with frameworks like LangChain. Real-world use cases include Karate Combat (governance tokens), Equity Lab (verifiable compute with Nvidia), Neuron (IoT data logging), and Hyundai/Kia (CO2 monitoring). Ed concludes with details on hackathon bounties for AI, EVM, and cross-chain projects, encouraging developers to engage and innovate on Hedera. 00:00 Introduction 00:30 Hedera Technology Stack Overview 01:12 Consensus and Mirror Nodes 01:37 Developer Services: Consensus & Tokenization 02:24 EVM Compatibility & Hedera Governance 03:13 Hedera Consensus Service (HCS) Explained 04:13 DApp Architecture & SDKs 05:22 EVM Tools and Development Paths 05:48 Hedera Playground Demo Introduction 06:56 Account Credentials & Faucet 07:35 Using the Playground: Consensus Service Demo 09:09 Submitting Messages & Transaction Explorer 11:04 Token Creation & Airdrop Demo 14:08 Account Inspection & Asset Management 15:03 Additional Examples & Resources 15:26 Smart Contract Deployment with Contract Builder 17:53 Integrating with IDEs & Testing Contracts 18:21 Hedera Agent Kit SDK & AI Agents 19:40 Setting Up Agent Kit & API Keys 20:25 Agent Kit Capabilities & Automation 21:03 Hedera Ecosystem Tools & Integrations 21:34 Real-World Use Cases 22:53 Hackathon Bounties & Closing Remarks _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ 🇺🇸 *ETHGlobal New York* This workshop is specifically for ETHGlobal New York, a 3-day hackathon held August 15-17, bringing together the most skilled web3 developers, designers and product builders from all around the globe for a weekend-long adventure to advance the Ethereum ecosystem!
