mentor applications open!
Kasa kay public!
The ETHMumbai team is back from our mini work retreat and straight back to building. December’s been moving fast, and last week was all about shipping, learning, and watching the community show up yet again.
Challenge #2: done and dusted
Last week, we dropped our second developer challenge and asked you to do something deceptively hard: take PeerDAS, a deeply technical Ethereum scalability upgrade, and explain it in a way that even non-technical folks would understand
The responses were strong. Clear explanations, good structure, and some very clean takes on PeerDAS. We’ve announced the winners, and if you missed them, go check them here for some solid inspiration.
If you didn’t win this time, don’t stress. Check out Challenge #3!
Challenge #3 is live!
This week’s challenge is a design one. Your task is to design a POAP for ETHMumbai 2026 that people would love to flaunt
It must include the line “I attended ETHMumbai 2026” and follow the ETHMumbai brand guidelines, but beyond that, this is your playground.
Submissions, as always, are to quote the announcement tweet. Build in public, share your work, and show us what you’ve got.
Apply to Mentor at ETHMumbai 2026
As we gear up for the BEST Hackathon, we’re opening up mentor applications. If you enjoy solving problems, answering tough questions, spotting bugs, and helping teams stay on track, this one’s for you.
You don’t need to have mentored before, just the willingness to help builders do their BEST work.
A few things to keep in mind:
The hackathon runs from 13th–15th March 2026
Travel and accommodation are self-covered
Mentor applications close on 30th December 2025
If guiding the next wave of Ethereum builders sounds like your thing, apply now.
Chala bhetu ya,
ETHMumbai Mitra Mandal
