ETHGlobal Mumbai is a three day in-person hackathon at the Jio World Convention Centre in Bandra Kurla Complex, Mumbai, running 6 to 8 November 2026. ETHGlobal expects 800 or more attendees, 10 or more protocols and around 29 workshops, with technical mentorship, workshops and a beginner-friendly on-ramp. 125,000 USD is available in prizes, with published partner allocations of 20,000 USD each from World and 1inch, 15,000 USD each from 0G, the Uniswap Foundation and Arkiv, and 10,000 USD from ENS. Teams are 1 to 5 people and may apply for up to three sponsor SDK prizes. As with the rest of ETHGlobal's 2026 season, projects do not have to start from an empty repository: hackers may extend an open source repo they already maintain, or ship a new feature on an existing product and release it as open source. Pragma Mumbai, ETHGlobal's conference day, runs the day before on 5 November 2026.
