As time goes by, the internet continues to evolve from Web 2.0 into Web 3.0. Hence, it is important for you to focus on the future of the internet and how to take the most out of Web 3.0 technologies.
Basically, every time you want to make a crypto transaction, you have to use your wallet address — a long string of numbers and letters. These long addresses are not only confusing but have also resulted in losses due to errors and scams. This is where The Ethereum Name Service (ENS) NFT domains begin make things a tad bit simpler.

What is the Ethereum Name Service (ENS)?
The Ethereum Name Service is a “distributed, open, and extensible naming system based on the Ethereum blockchain”. Put simply, it allows users to create a simple and easy-to-remember name for all their wallet addresses and decentralized websites.
To illustrate, instead of a confusing address like “0xAB25FF3F5A8S18699855668A2ADA096545FBA2D695E”, you can simply use “Jane.eth”. Jane.eth will be your ENS domain where you can get all your tokens and NFTs. You can buy and manage your own ENS domains, making blockchain transactions much easier.
How Does ENS Work?
ENS works similar to the Internet’s Domain Name Service (DNS). A DNS transforms IP addresses — a string of numbers — into human-friendly domain names called a URL. Similarly, the Ethereum Name Service converts machine-readable addresses to human-readable addresses.
To understand how ENS works, you have to first understand what it is made of. Essentially, ENS includes two Ethereum smart contracts. The first, called registry, records all the domain names. Each domain name consists of the owner’s details, the “caching time-to-live” of all the domain records, and the link to the resolver.
Now, a resolver is the second smart contract responsible for translating names into addresses and vice versa. Essentially, the resolver matches each domain to its user, address, IPFS content hash, or website. As the ENS domain name uses the ERC-721 standard, you can sell the domain to others, just as with NFTs.
What can you do with an Ethereum Name Service (ENS) domain?
Basically, ENS domains help users to change their long, illegible wallet addresses into easy-to-remember names. Think of this as saving someone’s number on your phone using their name. You don’t have to dial the number each time to call the person — you simply have to search for their name. In the same way, ENS makes blockchain transactions much simpler, with a lower chance of making errors.
Once you get your domain, you can link it to your public wallets, websites, smart contracts, or transactions. As an ENS domain owner, you can also create subdomains to link to other data. For example, email.jane.eth or website.jane.eth.
How to get an ENS domain
Before proceeding with these steps, you should have a small amount of ETH in your wallet. Then you can use it to pay the ENS registration fees and transaction fees linked with your domain. Here are the steps you can follow to get the job done.
Open a browser that supports Ethereum
As the very first thing, you will need to open a browser with MetaMask account installed. I’d recommend Chrome with MetaMask extension built. In case you don’t have a crypto wallet, you should think about creating one. You can instantly learn here how to create a MetaMask wallet. If you’re not thinking of making a MetaMask wallet, you can also set up a Coinbase wallet or a Trustwallet.Visit ENS domains website
As a second step, type in and visit app.ens.domains. This is the website where you will be purchasing your ENS domain. It is a simple website where you will be able to search for ENS domains based on your preferences.
- Locate and register your ENS
As mentioned in the previous step, you may search for the ENS domain you prefer to buy. You just need to enter the domain name, and the top level domain “.eth” will be automatically assigned.
The domain name you search for can either be available or unavailable. In case the domain name is not available, it will be possible for you to see the specific address where it is registered with. On top of that, you can also see the expiration date of the domain.
But if the domain name is available, you will be allowed to go ahead and register it. You can pay for the number of years you wish to register the domain. It is possible for you to extend the domain validity period at a later stage based on your preferences as well.
- Confirm your domain registration
The next step would be to use your crypto wallet and complete the transaction. This is where you will be asked to pay the registration fee linked with the domain name. The fee would vary depending on the number of years you buy the domain for.
To make the payment, you should connect your ETH wallet, and you will get some prompts to sign the migration of ens address to your account and money in the form of ETH will be deducted for this purchase too. If you don’t know how to do that, you can refer to this guide to send money using MetaMask wallet. After making the transaction from your ETH wallet, you should wait until the ENS app confirms it.
It will take some time for ENS app to confirm the registration request. That’s because it will validate that nobody else tries to register the specific domain name at the same instance. So please, be patient and wait 🙂
- Start using your ENS domain
Now you have an .eth domain under your name. You can share it to send, receive or store tokens in your address.
With a recent ENS update, you are now able to import your same DNS domain name to the ENS name as well. By going through this integration, you can use the ENS name in numerous other applications, which include Web 3.0 profiles and Web 3.0 username. This will eventually allow you to have complete key to the future Web 3.0.

It is also important to keep in mind that all ENS domains follow the ERC-721 standard. Therefore, you will be able to continue with using them in the form of an NFT. In other words, you have the freedom to treat ENS names in a similar way on how you treat NFTs. You will therefore be able to proceed with buying, trading, selling your ENS names to other accounts, wallets, and exchanges.
When you get hold of the right ENS, there is no need to worry too much about remembering your wallet address. That’s because it is easily memorable.
