Ed3zapp

Problem Statement

Learner's drop out rate is up by 67 % with most of them leaving due to a lack of Motivation and engaging content. We need to fix this problem by focusing on ways to Motivate the users ,Personalise and Reward their learning journey. For Course Creators, Inability to influence learners behavior and delayed payments. For Platform, expensive to onboard new learners and attract new Course Creators.

Our solution

We created a dApp that can connect learner and content creator together to achieve learning goals, that can create business impact for the organization. Content creator can signup, create courses, assign reward for courses. Learners can signup, purchase and learn the courses, take assessment and earn rewards in USDCx super token. Learners can unwrap the token to stable coin and withdraw to their exchange account.
