## What it is
Solidity smart contract implementations for the Ethereum Name Service (ENS), including the registry, registrars, and compiled JSON contracts published as an npm package. This repository is deprecated and superseded by ensdomains/ens-contracts.

## Use cases
- deploy an ENS registry to a local Ethereum test network
- get compiled ENS contract ABIs as an npm package
- run a first-in-first-served registrar for .eth subdomains
- integrate ENS namehash resolution into a dapp
- understand how the ENS registry and registrar contracts work

## When to choose
- you need the historical ENS registry or FIFS registrar contracts for legacy deployments
- you are studying the original ENS contract design

## When to avoid
- you want current, maintained ENS contracts - use ensdomains/ens-contracts instead
- you need modern resolvers or ENSV2 features
- you are building a new dapp integrating ENS
