Crypto domains and ENS names: how to value an on-chain digital property

An ENS name is a domain that happens to live on-chain

If you have read our pillar on digital assets as an alternative asset class, the move here is small: an ENS name is a domain. It is registered, it points somewhere, it can be transferred. The difference is where the registry lives. A .com registry is operated by a private company under contract with ICANN; the Ethereum Name Service registry is a pair of smart contracts that anyone can read.

Each ENS name is an ERC-721 token, which is what lets it trade on NFT marketplaces. That property — every name is a freely transferable token rather than a registry-locked record — is what gives ENS its public liquidity.

You can pull a floor price and recent sales for the whole collection on CoinGecko's ENS page or NFT Price Floor. Try doing that with a .com; you cannot.

How the engine actually values a name

The deterministic part of the valuation reads three signals: character count, scarcity tier, and recent sold comps. Registration fees on ENS are public and scale by length — roughly $5 per year for five-character and longer names, ~$160 per year for four-character names, and ~$640 per year for three-character names — all denominated in ETH. The same character-count gradient shows up on the secondary market: shorter is rarer, rarer commands a premium.

The second signal is scarcity beyond pure length: collector sets like the so-called '10k club' (the four-digit numeric names 0000.eth through 9999.eth) trade at a premium because the supply is fixed at 10,000 names and the set has cultural weight. A six-character common-English noun and a four-digit numeric name can have nothing in common in length but trade in the same neighborhood for completely different reasons.

The third signal is sold comps. Names that resemble yours on character count, semantic shape, or scarcity tier give the band.

The two highest public sales we cite are 555.eth at 55.5 ETH in April 2025 (reported on BeInCrypto and Coinfomania, worth roughly $160,000 at the time) and an earlier sale at 127 ETH (~$249,000 in 2022). Those are anchors at the very top of the distribution, not typical outcomes.

Why the ETH denomination matters more than people think

Here is the trap nobody pricing an ENS name talks about enough: the unit of account is volatile. A name that 'sold for $160K' really sold for 55.5 ETH on a specific day. If you walk into negotiation a year later quoting that USD figure, but ETH has moved sideways or down, you are negotiating against a number that no longer reflects what your buyer would have to spend.

Real Site Worth handles this by always producing the band in both units — an ETH range and a USD range computed from a recent spot rate — and by attaching a wider confidence interval to ENS estimates than we would to a comparable .com name. The same applies to other NFT-class digital properties: domain-like collectibles whose floor price moves with ETH inherit ETH's volatility before any property-specific signal is added.

If you want the conventional-domain side of this idea, our piece on aged-domain value walks through the inputs without the on-chain layer, and the TLD impact on rank and resale post is the closest sibling to the character-count story above.

What we will not value, and why

Two things sit outside what our engine will quote a range on, and we want to be honest about both. First, generative-art NFT collections (apes, punks, generative-PFP collections) are not domains; they are art markets whose price action is driven by community attention and trader flow as much as by any property-level signal we could read. We do not value those.

Second, anything where the seller would have to make a forward-looking claim — 'ETH will be at X by Y' — is not a valuation, it is a forecast. We do not produce forecasts. Our range reads recent comps and the property in front of us; if the market moves before you transact, the band moves with it.

Where this fits in the broader class

ENS names are one slice of the digital-assets class our pillar describes. They sit between a conventional domain (clear comps, slow but predictable liquidity, USD-denominated) and a pure crypto position (continuous market, no property-level signal). Treating them as 'just NFTs' under-prices what is actually a tradable domain; treating them as 'just domains' under-prices the unit-of-account risk.

For the cross-class comparison readers usually want next — gold vs bitcoin vs digital property as a store of value — we wrote that up separately as the next spoke in this silo: gold vs bitcoin vs domains as a store of value.
