How it's made
Challenges we ran into The configuration of the VCOP Protocol’s contract system required writing two deployment-and-configuration scripts and implementing advanced permission management, setting up the Uniswap hooks for effective pool stabilization, and integrating the front end using OnchainKit so that end users can interact with the protocol. This last part was perhaps the most challenging, as it introduced many bugs and errors for some reason.
