web3-eth-ens
Advanced tools
This package has ENS functions for interacting with Ethereum Name Service.
The web3-eth-ens package is a part of the Web3.js library that provides functionality for interacting with the Ethereum Name Service (ENS). ENS is a distributed, open, and extensible naming system based on the Ethereum blockchain. It allows users to resolve human-readable names like 'myname.eth' into machine-readable identifiers such as Ethereum addresses, content hashes, and metadata.
Resolving ENS Names to Ethereum Addresses
This feature allows you to resolve a human-readable ENS name to an Ethereum address. The code sample demonstrates how to use the web3-eth-ens package to resolve 'myname.eth' to its corresponding Ethereum address.
const Web3 = require('web3');
const ENS = require('web3-eth-ens');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
const ens = new ENS(web3);
async function resolveENSName(name) {
try {
const address = await ens.getAddress(name);
console.log(`Address for ${name}: ${address}`);
} catch (error) {
console.error(`Error resolving ENS name: ${error}`);
}
}
resolveENSName('myname.eth');Reverse Resolution (Address to ENS Name)
This feature allows you to perform a reverse resolution, converting an Ethereum address back to its associated ENS name. The code sample demonstrates how to use the web3-eth-ens package to reverse resolve an Ethereum address to its ENS name.
const Web3 = require('web3');
const ENS = require('web3-eth-ens');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
const ens = new ENS(web3);
async function reverseResolveAddress(address) {
try {
const name = await ens.getName(address);
console.log(`ENS name for ${address}: ${name}`);
} catch (error) {
console.error(`Error reverse resolving address: ${error}`);
}
}
reverseResolveAddress('0x1234567890abcdef1234567890abcdef12345678');Setting ENS Records
This feature allows you to set ENS records, such as associating an ENS name with an Ethereum address. The code sample demonstrates how to use the web3-eth-ens package to set the address for 'myname.eth' to a specified Ethereum address.
const Web3 = require('web3');
const ENS = require('web3-eth-ens');
const web3 = new Web3('https://mainnet.infura.io/v3/YOUR_INFURA_PROJECT_ID');
const ens = new ENS(web3);
async function setENSRecord(name, address) {
try {
const accounts = await web3.eth.getAccounts();
await ens.setAddress(name, address, { from: accounts[0] });
console.log(`Set address for ${name} to ${address}`);
} catch (error) {
console.error(`Error setting ENS record: ${error}`);
}
}
setENSRecord('myname.eth', '0x1234567890abcdef1234567890abcdef12345678');The eth-ens-namehash package provides utilities for working with ENS names, including namehashing and normalization. It is more focused on the technical aspects of ENS name processing, whereas web3-eth-ens provides higher-level functionality for interacting with the ENS system.
The ethers package is a complete Ethereum library and includes support for ENS. It provides functionalities for resolving ENS names, reverse resolution, and interacting with ENS records. Compared to web3-eth-ens, ethers is a more comprehensive library that covers a broader range of Ethereum-related functionalities.
This is a sub-package of web3.js.
