LaunchpadFactory

Overview

The LaunchpadFactory contract facilitates the creation and management of launchpad requests. This contract allows users to request a launchpad for their token sale, which can then be approved or canceled by the owner of the contract. The factory also handles the creation of launchpads and manages the vesting contracts for the tokens.
