## Description

Learn how to integrate Ethereum Name Service (ENS) into your applications in this ETHGlobal Taipei 2025 workshop with Greg Skril. Discover how ENS transforms crypto addresses into human-readable names (like greg.eth) for seamless user experiences across Web3.

The workshop covers forward/reverse resolution, on-chain vs. off-chain resolvers, and CCIP-read for L2 subnames using tools like Duran. With $10K in prizes for best ENS implementations (including decentralized website hosting and multi-chain identity solutions), this session is ideal for developers building wallets, dApps, or identity systems. Includes live demos of L2 subname deployment and ENS profile customization with text records.
