ENS Name Resolver

Resolve ENS names to Ethereum addresses

■ 01

What is ENS?

Ethereum Name Service (ENS) is a distributed, open naming system based on the Ethereum blockchain. It maps human-readable names like 'alice.eth' to Ethereum addresses, making it easier to send transactions and interact…

■ 02

How does it work?

ENS uses smart contracts to store name-to-address mappings on the Ethereum blockchain. When you resolve an ENS name, the system queries these contracts to retrieve the associated Ethereum address.

■ 03

Sample Cases

Covers Resolve vitalik.eth and Resolve nick.eth so you can compare common inputs and outputs quickly.
