ENS Labs contributes to and maintains the Ethereum Name Service (ENS) ecosystem, including protocol smart contracts, the Manager App for managing ENS names, and ENS Improvement Proposals (ENSIPs) that define and standardize protocol specifications. The documentation covers ENS architecture (registries, registrars, resolvers), standards such as text records and contenthash, reverse resolution, multichain address/primary name resolution, interface discovery, metadata events, and offchain lookup protocols. The site targets developers, integrators, and users who build with or interact with ENS infrastructure on Ethereum and compatible environments.
