Ethereum Name Service (ENS) review
A naming service for .eth registration, wallet resolution, identity records, and app integration.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Ethereum Name Service (ENS) is a blockchain naming service for people and teams who want readable names for wallet addresses, profiles, and applications. It supports .eth registration and renewal, and lets users import DNS domains they already own. Names can resolve to wallet addresses, carry profile records such as avatars and social handles, and be set as a primary name. Users can also create and manage subnames, while developers can integrate ENS resolution and records into applications.
Pricing depends on .eth name length, with annual registration and renewal at the same rate. According to the vendor's pricing details, names with five or more characters cost $5 per name per year; four-character names cost $160 per year, and three-character names cost $640 per year. Fees are paid in ETH on Ethereum Mainnet, with network gas charged in addition. That makes ENS more accessible for longer names, while shorter names carry substantially higher annual fees. Imported DNS domains are brought by the user rather than sold by ENS.
ENS is a fit for buyers who want wallet resolution and identity records alongside domain registration, or developers adding those capabilities to applications. The published product details describe 575 integrations, plus web and API access, and documentation for developers. Its core registration and resolution architecture is Ethereum-based, so buyers seeking naming across multiple blockchain systems may prefer to evaluate alternatives. Choose ENS when the Ethereum naming ecosystem and its profile and subname features suit the use case; look elsewhere if shorter-name annual fees or Ethereum-specific operation are a poor fit.
