Set "confirmed" to "false" on a chain reorganization

Most apps will want a quick update of transaction data, but still be able to handle chain reorgs if they happen. Waiting until ā€œconfirmedā€ is set to ā€œtrueā€ isnā€™t an option, because that takes 4 minutes (at least on Polygon). What Iā€™d really like to do is to update the data immediately, and then if I get a ā€œconfirmed: falseā€, I can fix the data based on that change, as long as Iā€™m careful, and checking: ```
if(typeof confirmed === ā€˜booleanā€™ && confirmed === false) { revert the change }
