To delete (unlink) a wallet in the Coinosh app:
Open the app and go to the Settings menu.
Look for the "Manage Wallets" section and tap on it.
Locate the wallet you want to delete and tap on the "more" button next to it.
On the settings screen for the wallet, you will find an option to "unlink" the wallet.
Tap on the "unlink" button to proceed with the deletion process.
By unlinking the wallet, you will remove it from the Coinosh app and delete all associated data.
It's important to note that this action does not delete any transactions or balances from the blockchain itself. If you wish to restore a deleted wallet in the future, you will need the private key (mnemonic phrase) and passphrase (if applicable) associated with that wallet. Without this information, it will not be possible to restore access to the deleted wallet.
