Identity for Apps, Agents & More with
summary
ENS maps names to data with forward and reverse resolution, primary names via reverse registrars on six chains, and supports signing to set names for others; subnames are free and infinite and can be deployed to L2s with Durin (durin.dev). ENS stores arbitrary text records (see ENSIP-26 for agent metadata) and previews ENS V2 on Sepolia with hierarchical registries and fine-grained permissions plus an ENS CLI. Hackathon prize pools total $20,000 (including a $6,000 pool and $4,000 continuity).
