Collectible usernames behave exactly like ordinary ones in Telegram. The difference is ownership: a collectible username is a permanent asset recorded on the TON blockchain, so it can be bought, sold and transferred rather than merely held.
Side by side
| Basic username | Collectible username | |
|---|---|---|
| Appears in global search | Yes | Yes |
| t.me and username.t.me links | Yes | Yes |
| How you get it | Claim a free one | Acquire it, usually on Fragment |
| Ownership | Held while you use it | Permanent, verified on TON |
| Transferable | No | Yes, and freely assignable |
Why ownership changes things
A basic username returns to the pool if you clear it. A collectible one is yours as an asset, so you can assign it to an account, move it to another, or sell it, and the record of who holds it does not depend on Telegram's internal state. Short, memorable names have real value to businesses and creators, and this is the mechanism that lets them be acquired properly instead of through informal arrangements that nothing enforces.
Where they are traded
Fragment is the platform built for this, with auctions for names that have never been claimed and a marketplace for ones already owned. Buying there transfers the asset to you on-chain.
