Web3 Domain Value Calculator

Blockchain naming systems map a human-readable label to a wallet address, a content hash, and arbitrary text records. Because the namespace is open and every label is unique, pricing behaves like any market in scarce identifiers, and length dominates. There are only 36 single-character labels over the usual alphanumeric set, 1,296 two-character labels and 46,656 three-character labels, so the supply curve is steeply convex and the base value in this model falls by roughly a factor of three per added character until it flattens past ten characters. The remaining terms are multiplicative adjustments rather than additions: the extension multiplier reflects that .eth resolves natively in far more wallets and clients than alternative suffixes, the category multiplier prices commercial intent, a dictionary-word bonus captures the premium buyers pay for pronounceable names, and hyphens and digits act as discounts because they degrade verbal transfer and recall. Treat the output as a rough comparable-sales prior, not an appraisal. Web3 name markets are thin: most registrations never trade, medians sit far below headline sales, and a single auction can distort perceived value for a whole category. Carrying costs matter too. ENS charges annual renewals denominated in USD and paid in ETH, on the order of 5 dollars a year for names of five characters or more, about 160 dollars for four characters and about 640 dollars for three, so a speculative three-letter name costs thousands of dollars to hold for a decade. Trademarked terms carry legal exposure, and a name that is worthless without an active resolver record has utility value only while the underlying registry remains widely supported.

Naming on a blockchain predates Ethereum. Namecoin, launched in April 2011 as one of the first Bitcoin forks, created the .bit namespace to demonstrate censorship-resistant DNS, though it never achieved meaningful browser support. The Ethereum Name Service went live on 4 May 2017, developed by Nick Johnson while at the Ethereum Foundation, and initially allocated .eth names through Vickrey sealed-bid auctions with the winning bid locked as a deposit. That mechanism was replaced in May 2019 by a permanent registrar using annual rental pricing, which converted names from one-time purchases into leased assets and introduced the length-tiered fee schedule still in use. Expired names pass through a grace period and then a temporary premium that decays over about three weeks, so lapsed registrations return to the market by auction rather than sitting idle. Unstoppable Domains, founded in 2018, took the opposite approach with one-time purchase and no renewals, issuing .crypto and later .nft, .wallet and .dao as NFTs, eventually minting on Polygon to avoid Ethereum gas costs. ENS governance was decentralized in November 2021 with the launch of the ENS DAO and a retroactive token distribution to existing name holders. Since then most trading has moved onto general NFT marketplaces and ENS-specific venues, giving the market its first reasonably public price history.
