Wallet disconnected. Permission still alive.
Closing a dApp's tab is not the blockchain equivalent of changing the locks.
On Ethereum, an existing token spending approval can remain active after you disconnect your wallet from a website. Disconnecting the session and revoking the token allowance are different actions.
An unlimited allowance can expose all holdings of that particular token to the approved spender. It does not magically become harmless because you stopped visiting the site.
The useful questions are: which contract, which token, how much permission, and is it still needed?
Don't let a random “security helper” in your DMs choose the answers. Never share a recovery phrase or sign something you don't understand.
