AAVE Checks

So casual users often want to leverage funds in the context of a secure and decentralized environment. This means when funds are sent the actions and signature process must be abstracted away for the user.

In this PoC the concept is to mediate payment between two parties with an invoice that also also for the possibility of using credit, similar to Apple's BNPL or more simple credit cards. This example simplifies the scenario to just checks but has wider possibilities and definitive GTM strategy targeting businesses and older users.

The protocol is designed by having three primary parties: Sender, Endorser, and Mediator

The Sender and Endorser are user parties and the Mediator is an AAVE GHO facilitator.

When a check event is create by a Sender party it is cataloged on a global check list as a temporary and unsigned userop. The Mediator will both sign will facilitator will validate the userop locally and send that check to a private mempool. The Endorse can see all event log relevant to their account and when they select a check they are signing that check and sending said check to the entrypoint where the GHO facilitator handles the debt arbitration.

Settled check events are also logged and aggregated for the user as a consistent account.
