Cyberconnect Discount Middlewares

This repository contains a collection of Cyberconnect middlewares to apply a discount on an essence in different ways. CollectPaidMw.sol is used as the base for writing these new middlewares.

Usage:

Option 1:

The interfaces and bytecodes of all the contracts are available. You can use them to deploy your own contract using deploy.js.

Option 2:

To compile and deploy the contracts you can clone the original cybercontracts repo, and copy your desired .sol file under essence directory. Next, follow the deployment guide to compile and deploy.
