An address on Ethereum is purposely made to be difficult to remember and troublesome to type. We would never think to type 0x71C7656EC7ab88b098defB751B7401B5f6d8976F each time we need to send some ETH, nor would we ask a friend to "send ETH over to zero ex seven one...". Conversely, on every other inch of the Internet we would never think about typing long, nonsensical IP addresses into a web browser.
This is where Ethereum Name Service (ENS) comes in. ENS turns the complicated addresses in Ethereum into human-readable domain names.
For example, 0x71C7656EC7ab88b098defB751B7401B5f6d8976F could be named as etherscan.eth. Anyone that wants to interact with the address simply needs to remember etherscan.eth and type that into a dApp or wallet instead of copy pasting (and double and triple-checking) the address each time.
On Etherscan, we've enabled ENS domains to be shown directly on the website's interface as Name Tags.
How to Add an ENS Name Tag
To have the Name Tag displayed on Etherscan, you'll need to set up both forward and reverse resolution and point each to the same address & name.
Look for and register an available ENS domain here: app.ens.domains
Set reverse record
Check that your reverse record is set correctly
Make sure that the forward resolved address (the first address under Records) is set to the same address used for reverse record
Once you have completed the steps above, voila! You will see your ENS Name Tag displayed proudly on the Address page on Etherscan.
- An ENS domain may not necessarily be owned by the person or entity popularly associated with the name. For example, elon.eth and tesla.eth may have been bought by a random member of the Ethereum community instead of Elon Musk or Tesla, Inc. Please take care not to fall for any tricks related to any mis-association of names.
- Some domain names can be bought that includes characters from more than one Unicode alphabet. This may also be used to trick unsuspecting users. For example, the name vítalik.eth (with one i having an accent mark) could be used in a phishing attempt.
- If you prefer not to have your ENS domain displayed on Etherscan, simply remove either the forward or reverse record from the same address.
