SDK - Prevent Double Payments - Request Network V3 with 100% double payment prevention using onchain invoices and onchain expected amounts #1614
Description
Problem
At a smart contract level, the reference-based payment proxies don't prevent Double Payments.
Solution
Write a Request Network V3 that stores invoice expected amounts onchain so that the balance of a request can be checked at the smart contract level and overpayments can be 100% prevented.
Considerations
- How to handle multi-chain? What if the invoice (and expected amount) is stored on Gnosis, but payment is on Polygon?
Ideas
- Crosschain message bridges
- LayerZero
