Launching a Web3 project without registering your namespace first is a preventable mistake. Here is a practical framework for deciding what to register, on which chain, and when.

ENS names are NFTs on Ethereum. Transferring or selling one is not complicated, but there are a few gotchas around the registrant vs. controller distinction that trip people up.

Most ENS holders register a name and stop there. But the parent name you own lets you create subdomains for free and assign them to any address, content hash, or record you want.

You can register an ENS name and never set it as primary. Plenty of people do. But setting a primary name is what makes your .eth address show up across wallets and dApps instead of 0x...

Public ENS tools get throttled. Here is why it happens, what the error messages mean, and how to check hundreds of names reliably without hitting walls.

Most ENS holders know their name has an expiry date. Far fewer know what the 90-day grace period really means, how the premium auction works after that, and what to do if you miss the window.

ENS name squatting has been happening since 2017. If your brand has any Web3 visibility, someone may have already claimed your name. Here is how to check and what your options are.

Basenames launched with a free tier for Coinbase users and certain NFT holders. Some of those eligibility routes have closed or changed. Here is what still qualifies in 2026.

If you can only register one Web3 name right now, should it be ENS (.eth) or Basenames (.base.eth)? The answer depends more on how you use crypto than on which one sounds better.

A 3-character ENS name costs 0.1 ETH per year. A 5-character name costs 0.001 ETH. That is a 100x difference for two extra letters. Here is why the pricing works this way.

Both Basenames and ENS run on the same ENS protocol. But the gas costs, pricing, and ecosystem integrations are different enough that the choice matters depending on how you use Web3.

Short, memorable ENS and Basenames are disappearing fast. Registering your namespace early is one of the cheapest, most durable moves you can make in Web3.

Traditional domains have served the internet well — but Web3 domains like ENS and Basenames offer ownership, censorship resistance, and programmability that .com simply cannot match.
