Hi! I work at Stripe on our Bitcoin solution. We do not send funds back to the originating address but instead allow merchants to programmatically supply a refund address or alternatively handle this part for them by contacting the customer over email to provide a refund address to send the over-payments to. Hope that clarifies this particular point. Additionally, to compute over-payments, we rely on Coinbase notifying us of the amounts received on a receiver bitcoin address. In that instance Coinbase erroneously notified us that they received BTC .00231463 (~$5 at the time) instead of BTC 0.1154481, leading to our overpayments logic to not be triggered. We're investigating with Coinbase on what happened on their end and we'll make sure that the root cause gets fixed.
