Final Grant Report: Arbitrum <> DApp World
Executive Summary
We are excited to present the final report for the Arbitrum <> DApp World. This initiative was funded with a grant of $10,000 to build a comprehensive, structured, gamified learning track for Arbitrum, hosted on the DApp World platform. Over 2 months, we have successfully developed two full-fledged Arbitrum courses aimed at onboarding developers into the ecosystem, offering 10+ hrs of high-quality, interactive content in each track.
The educational content includes videos, readings, quizzes, assignments, and a certification mechanism. The courses are now live and accessible to all active Web3 developers on our platform.
