Linea Subnames (linea.eth)
Linea has become the first zkEVM Layer 2 to adopt the EIP-3668 standard in production, fulfilling the vision of operating ENS with lower gas costs and improved interoperability. Users can switch their wallet address to a human-readable domain, while developers can use CCIP Read (ERC-3668) for cross-chain data retrieval. Linea incorporates proof of humanity as part of their registration flow & requirements.
