ENS is the open-source naming standard for the Web3 ecosystem. It functions similarly to the internet's DNS (Domain Name System) but is built on decentralized Ethereum smart contracts. Users can register ".eth" names or import traditional DNS names (like .com or .org) to use as their Web3 identity. These names store multiple cryptocurrency addresses, allowing a single ENS name to receive ETH, BTC, SOL, and other assets.

The ENS ecosystem has moved toward mainstream payment integration and Layer 2 scalability:

PayPal & Venmo Integration: In late 2024, PayPal and Venmo integrated ENS into their payment flows. This allows millions of users to send crypto by typing an ENS name (e.g., "user.eth") directly into the search bar, automatically resolving the associated wallet address without leaving the app.

ENSv2 (Layer 2 Migration): Throughout 2025, ENS Labs advanced the ENSv2 architecture. This upgrade involves migrating the core registry to a Layer 2 network. The goal is to significantly lower the gas fees associated with registering, renewing, and managing subnames, making the protocol more viable for high-volume use cases.

Google Search Integration: Google expanded its crypto search features to include ENS resolution. Users can search for an ENS name directly in Google to view public blockchain details, such as the associated address and ETH balance, increasing the visibility of Web3 identities.

The ENS token is utilized strictly for governance within the ENS DAO:

Protocol Governance: ENS holders vote on the ENS Constitution, which defines the rules and guidelines for the community.

Treasury Management: The ENS protocol generates revenue from registration and renewal fees (in ETH). Token holders vote on how these funds are allocated to fund public goods, ecosystem grants, and core development.

Pricing Parameters: The DAO controls the pricing oracle that determines the cost of registering .eth names (currently priced in USD but paid in ETH).

Token Standard: ERC-20 (Governance)

Name Standard: ERC-721 (NFT) / ERC-1155 (Name Wrapper)

Key Feature: Human-readable mapping for wallet addresses

Governance: ENS DAO (On-Chain)
