Using your .trx name

A .trx name gives your Tron address a readable name. Tron Web3 Domains documents little beyond that, so this page stays short.

Basics

What does a .trx name do?

It lets people send and receive crypto on Tron with a memorable name, and it can carry a profile, an avatar and social links.[1]

How do you set up your .trx name?

Set it as your address's default domain, so apps can show it in place of your address. Tron Web3 Domains doesn't publish step-by-step help. No name yet? Check one.[3]

Advanced

Can you create subdomains under a .trx name?

Yes. Tron Web3 Domains says you can create unlimited subdomains and share them, for example with team members.[1, 2]

Can apps read your .trx name?

Yes, with the trondomainjs Node.js SDK: getOwner turns a name into its owner's address, and getDomain finds an address's default name. For a better-documented name service, see using a .eth name.[3]
