Usernames created on Stacks 1.0 can be used in the new web wallet for testing only on the Hiro Wallet for web. Usernames from Stacks 1.0 will show up in the web wallet, but any usernames registered on stacks 2.0 are not yet visible. All registered Stacks IDs were automatically renewed at the launch of Stacks 2.0 for one year.

Usernames can also be used with the older app.blockstack.org and Blockstack Browser, but only until they sunset on July 1, 2021
