How do you delete or reset Apple Cash history?

No. The iPhone is a single user device protected with your Passcode and the information is only viewable by you, unless you have given your Passcode to someone else. The Passcode is what is used for authorization to view your history.

You would be able to Factory Reset your iPhone and not set up Apple Cash again and the history would not be viewable, but I suspect that is not what you are looking for.

This is not something Apple would ever be able to implement. Federal Law requires that you have access to your accounts history. Being able to delete or modify records is just not permissible under current regulations. Sorry.

You can lock the Wallet app. Do a long press and select Require Face ID. Now it’s locked.
