The 42-character Ethereum addresses have become an iconic element of the web3 landscape. Unfortunately, remembering these lengthy strings is a daunting task for many users. The Ethereum Name Service (ENS) provides a solution through a decentralized naming system built on the Ethereum blockchain.
As of July 30th, ENS domains are now accessible on Linea, recognized as the fastest-growing zkEVM within the Ethereum ecosystem. Recent enhancements in Hyperledger Web3j enable developers to effortlessly integrate Linea ENS features into their Java applications, facilitating interaction with these user-friendly domain names throughout the Ethereum network.
Understanding Linea ENS
The integration of ENS on Linea represents a pivotal development. Linea, a zkEVM Layer 2 blockchain, has adopted the EIP-3668 standard – CCIP Read, which allows for the efficient functioning of ENS while offering reduced gas fees and enhanced interoperability. Domains under Linea ENS utilize the format name.linea.eth, providing users with a human-readable alternative to their Ethereum addresses, maintaining robust security and lower transaction costs.
This innovative system enhances the user experience, minimizes the risk of transaction errors, and boosts accessibility. Users can easily switch their wallet addresses to a readable domain. Moreover, developers can leverage CCIP Read (ERC-3668) for cross-chain data access.
ENS Integration in Linea
Support for Linea in Hyperledger Web3j
The Java library Hyperledger Web3j, designed for Ethereum interactions, now includes support for Linea ENS due to recent updates. We have incorporated the ENS registry contracts for both Linea Mainnet and Linea Sepolia testnet from their GitHub repository.
This upgrade allows developers to seamlessly add Linea ENS functionalities to their Java applications. They can resolve ENS names to addresses and perform reverse lookups from addresses back to Linea ENS domains. By supporting both Linea Mainnet and Linea Sepolia testnet, developers can easily test and deploy their solutions across various environments.
Example Code: Resolving Linea ENS with Hyperledger Web3j
Here’s a straightforward example demonstrating how to utilize ENS on the Linea network via Hyperledger Web3j:
This code snippet illustrates how to convert a Linea ENS domain (alex.linea.eth) into its corresponding Ethereum address, and vice versa. This feature is fully supported on both the Linea Mainnet and Linea Sepolia testnet, providing comprehensive support for developers throughout different deployment phases.
