ZIP-321 is a new ZIP that standardizes how URIs are handled in wallets. Especially interesting is the part that describes how multiple payments can be made from the same URI. Zecwallet currently doesn't have full support for this standard - especially the multi-payment URIs.
This proposal is to add support for ZIP-321, the zcash standard URI payments across all Zecwallet products:
The desktop apps already support multiple payments, so implementing ZIP-321 on the desktop apps is straightforward. For mobile apps, the multi-payments UI needs to be implemented on the send screen as well.
Very little execution risk on this, since the ZIP is very well written
No major downsides. The one issue might be the ZIP-321 is not 100% compatible with the currently implemented ad-hoc URI parsing on Zecwallet (most notably, the memo is encoded in base64 in the ZIP, while it is a URI-encoded in Zecwallet), so it might cause some incompatibilities.
However, we're not aware of any large-scale breaking deployments, so the disruption should be minimal.
The $6000 funding request represents 4 days worth of work at $187.5 per hour.
