That’s a wrap! ETHDenver 2019 has just finished up, and while everyone is exhausted, we couldn’t be more thrilled at how vibrant and active the community is!

¡Hola Zeppeliners! It’s that time again, when hackers, innovators, and Bufficorns converge on ETHDenver for a week of #buidl, #buidl, #buidl!

After the fun we had with last year’s Ethernaut hacking game, we’re releasing EthHunt, a new game to celebrate Zeppelin’s sponsorship of Devcon4!

As we’re wrapping up EthDenver 2018, the #gratitude hashtag falls short to say thanks to all the awesome people who contributed to make it an unforgettable event.
