When using Handcash to submit a payment and the BIP-270 server returns a paymentACK with an error > 1, I would have expected to have seen an error in the app rather than the payment complete. Is this an issue with how handcash are handling the paymentACK message or something missing from the Spec.
In the protocol spec it defines the PaymentACK message as shown: https://github.com/moneybutton/bips/blob/master/bip-0270.mediawiki#paymentack.
| error |
A number indicating why the transaction was not accepted. 0 or undefined indicates no error. A 1 or any other positive integer indicates an error. The errors are left undefined for now; it is recommended only to use "1" and to fill the memo with a textual explanation about why the transaction was not accepted until further numbers are defined and standardized. |
