EtherPunk 2021, the first ETHIndia Online Hackathon in 2021 that kicked off on January 22, was a call to arms bringing together thousands of developers, industry experts, advisors, mentors, and companies to innovate and build decentralized applications with the potential of mass adoption.

We received 2500+ applications this time, from which the top hackers were accepted to build and showcase their hacks at EtherPunk 2021.

A big shoutout to our sponsors for mentoring our hackers and setting up bounties worth $25,000+ to incentivize and reward their efforts!

Speaker Sessions

We invited the who's who of the Blockchain Industry to ignite the spark in our hackers, including Austin Griffith and Balaji Srinivasan.

The various sessions covered everything from how to start building on Ethereum, Social Crypto, how DeFi is shaping the way we think about finance, and the endless career opportunities available in the Crypto Space. Our sponsor workshops helped the hackers get interesting insights about their platforms and how to tailor them to suit their Dapp and bag those bounties 💰
