In this article I want to walk through the Ethereum Name Service, usually shortened to ENS, and specifically how it can be used by a brand rather than just an individual. Most articles on ENS stop at "it turns a long wallet address into a readable name" and leave it there. That is true, but it undersells what ENS can do for a business or a project. We will cover what ENS actually is, how it works under the hood, the concrete ways a brand can use it and the practical pitfalls to watch for.
A quick note on who is writing this. My name is Paul and I am a Web3 developer focused on Solidity smart contracts and the Ethereum ecosystem. ENS is one of those pieces of infrastructure I keep running into, and it is genuinely useful, so it is worth a proper explainer. As always, feel free to reach out.
What Is the Ethereum Name Service?
The Ethereum Name Service is a naming system built on Ethereum. At the simplest level, it maps a human-readable name like yourbrand.eth to machine-readable data such as an Ethereum wallet address, the address of another cryptocurrency, a content hash for a website or arbitrary metadata.
The comparison everyone reaches for is DNS, the system that turns example.com into the IP address your browser actually connects to. ENS has similar goals for the decentralized web. Instead of asking someone to send funds to a 42-character hexadecimal string, you ask them to send funds to yourbrand.eth. The name resolves to the address behind the scenes.
The difference that matters for a brand is ownership. A traditional domain is leased through a registrar and ultimately sits within a centralized system. An ENS name is issued as an NFT on Ethereum, and ownership is secured by the blockchain itself. Once it is in your wallet, it is yours to hold, transfer or sell, with no intermediary able to quietly reassign it.
How ENS Works Under the Hood
ENS is built from a small set of smart contracts. Understanding them helps you understand what you actually control when you own a name.
The Registry is the central contract. It records every ENS name, who owns it and which resolver it uses. It is deliberately simple, which keeps it robust.
The Registrar is the contract that controls a top-level domain and sets the rules for issuing names under it. The .ethregistrar is the one most people interact with, and it issues .eth names as NFTs.
The Resolver is the contract that does the actual translation. When an application looks up yourbrand.eth, the resolver is what returns the wallet address, the website content hash, the avatar image or whatever other records you have set.
This modular design has a useful consequence. Because a name is just an entry in the registry pointing at a resolver, you keep full control over what your name points to and you can update those records whenever you want. You can also create subdomains, and this is where things get interesting for brands.
Why a Brand Should Care About ENS
Here is the part most introductory articles skip. ENS is not only a convenience feature for individuals. For a brand operating anywhere near Web3, it touches identity, payments, trust and even hosting. Let me break down the concrete use cases.
A Single Recognizable Identity
If your project receives crypto payments, donations or any kind of on-chain interaction, yourbrand.eth is far easier to communicate than a raw address. It fits on a business card, in a video, in a podcast mention or in a conference slide. People can type it from memory. They can also sanity-check it, since yourbrand.eth is self-evidently your brand in a way that 0x8f3a... never will be.
Trust and Phishing Resistance
Crypto is full of address-swapping scams and lookalike wallets. A well-known ENS name that your audience recognizes becomes a verification anchor. When your community knows that payments go to yourbrand.eth and nowhere else, an attacker posting a random hex address has a much harder time. The name itself becomes part of your brand's security posture.
Subdomains for Teams, Products and Campaigns
This is the feature I think brands underuse. Once you own yourbrand.eth, you can issue subdomains under it, such as pay.yourbrand.eth, treasury.yourbrand.eth, support.yourbrand.eth or alice.yourbrand.eth for a team member.
Think about what that gives you. Every subdomain is verifiably part of your brand because it sits under a name you control. You can hand out wallet-linked identities to staff that are visibly official. You can separate a public donations address from an internal treasury address while keeping both clearly branded. For an organization, this turns ENS from a single label into a structured namespace.
Pointing to a Decentralized Website
An ENS name can hold a content hash, which means it can point to a website hosted on decentralized storage such as IPFS. Through ENS-aware browsers and gateways, yourbrand.eth can resolve to an actual site. For a brand that wants a censorship-resistant presence or simply wants to practice what it preaches about decentralization, this is a real option rather than a gimmick.
Carrying Your Existing Domain Into Web3
ENS supports interoperability with traditional DNS. If your brand already owns yourbrand.com, it is possible to use that DNS name within ENS rather than being forced onto a separate .eth name. For an established brand, this matters. It means your Web3 identity can be a continuation of the domain your audience already knows instead of a disconnected new handle.
How to Register and Set Up an ENS Name
The process is straightforward. Here is the practical flow.
First, you need an Ethereum wallet such as MetaMask, Rainbow or Coinbase Wallet, funded with a small amount of ETH to cover the registration fee and gas.
Second, go to the official ENS application and search for the name you want. If it is available, the price is shown directly.
Third, complete the registration. This requires two on-chain transactions with a short wait between them. The two-step process exists to prevent frontrunning, where someone watching the network could otherwise see your request and grab the name first. You will confirm in your wallet twice.
Fourth, set your records. Point the name at your wallet address, set a primary name (reverse resolution) so applications can display yourbrand.eth instead of your address, and add any other records you want such as an avatar, a URL or social handles.
Pricing depends on length. Names of five or more characters sit at a low base rate of roughly five US dollars per year. Four-character names cost more, and three-character names cost considerably more, with the price reflecting their scarcity. On top of the registration fee you pay gas, which varies with network conditions.
[2026 Update note: Network upgrades have dramatically reduced the gas cost of ENS operations compared to earlier years, which removes one of the long-standing complaints about registering and managing names. There is also a major protocol upgrade, referred to as ENSv2, in progress. The core concepts in this article (the registry, resolvers, subdomains, ownership as an NFT) remain the same, but anyone setting up ENS for a brand should check the current state of the app and protocol for the latest specifics on cost and features.]
Pitfalls and Practical Advice
ENS is useful, but there are a few traps worth knowing before you commit a brand to it.
Renewal discipline. An ENS name is registered for a period, not forever. If you let it lapse and miss the grace period that follows expiry, the name can become available to others. For a brand this would be a serious problem. Register for multiple years, set calendar reminders and treat renewal with the same seriousness you treat your DNS domain renewals.
Name squatting. Popular brand names may already be registered by someone else, sometimes by people hoping to resell them. Check early. The sooner your brand secures its namespace, the less likely you are to face this. If your exact name is taken, think carefully before paying a large secondary-market price, and get legal advice if there is a trademark dimension.
Custody is on you. Because the name lives in your wallet as an NFT, the security of that wallet is the security of your brand's ENS identity. If the wallet is compromised, the name can be transferred away. For an organization, this argues strongly for holding important names in a multi-signature wallet rather than a single private key controlled by one person.
It does not replace everything. ENS is an identity and naming layer. It does not by itself give you a website, handle your customer payments end to end or manage your community. It is one useful component, and it works best when you are clear about the specific job you are asking it to do.
Verify the official app. Because ENS is valuable, fake versions of the registration interface exist. Always confirm you are using the official ENS application before connecting a wallet or signing anything.
Frequently Asked Questions
Is an ENS name the same as a website domain? Not exactly. A traditional domain like yourbrand.com is leased through the DNS system. An ENS name is an NFT on Ethereum that you own outright. They can work together, since ENS supports using existing DNS names, but the ownership model is different.
How much does an ENS name cost for a brand? For a typical brand name of five or more characters, the base registration fee is low, in the range of a few US dollars per year, plus gas. Shorter names cost significantly more. The bigger cost to plan for is discipline around renewals, not the fee itself.
Can I get subdomains for my team? Yes. Once you own a name like yourbrand.eth, you can issue subdomains such as alice.yourbrand.eth or pay.yourbrand.eth. This is one of the most practical features for an organization, since every subdomain is verifiably part of your namespace.
What happens if my ENS name expires? After expiry there is a grace period during which you can still renew. If you miss that window, the name can become available for others to register. For a brand, missing a renewal could mean losing your on-chain identity, so treat renewals seriously.
Do I need to be a developer to use ENS? No. Registering a name and setting basic records is done through a user-friendly app and takes a few minutes. Developer knowledge helps if you want to do more advanced things like wiring ENS into your own application, but it is not required for brand setup.
Is ENS only for the Ethereum blockchain? ENS is built on Ethereum, but a single name can store addresses for multiple cryptocurrencies and can point to various kinds of data. Its identity role increasingly stretches across the wider Web3 ecosystem rather than staying limited to one chain.
Conclusion
ENS is one of those pieces of Web3 infrastructure that looks small at first glance and turns out to be quite deep once you actually use it. For an individual it is a convenience. For a brand it is closer to a namespace, a trust anchor and an identity layer rolled into one. You get a recognizable name, the ability to structure subdomains for teams and products, optional decentralized hosting and a verification point that helps your audience avoid scams.
It is not a magic solution and it comes with real responsibilities, renewal discipline and wallet security chief among them. But for any brand operating in or near Web3, securing your ENS namespace early and setting it up deliberately is a sensible, low-cost move. The naming layer of the decentralized web is still being built out, and the brands that claim their place in it now will be glad they did.
If you are exploring this for your own project and want to go deeper on the technical side, that is exactly the kind of thing I enjoy digging into. Go out there and learn.
