Avalanche Summit | Hackathon Recap: Summary and Prize Winners, powered by Encode Club

Published by AVAX on

A recap of the 3-day Avalanche Summit Hackathon, including the winners, sponsors, and photos; written by Encode Club.

The Avalanche Summit | Hackathon took place over the weekend of Friday March 25 — Sunday March 27, 2022. Powered by Encode Club, the hackathon followed the highly successful Avalanche Summit DevCon that took place earlier in the week. Both events took place at the historic Poble Espanyol in Barcelona, Spain, and the hackathon had more than 250 hackers attending with 56 projects submitted. Around $200k of prizes were given out at the end of the weekend.

Overview of the weekend

The weekend kicked off at lunchtime on Friday afternoon, with hackers submitting at 12pm on Sunday.

Throughout the weekend hackers worked hard, innovated and pushed the limits of burning the midnight oil to produce fantastic projects. Projects were primarily themed around Subnets, but there were also a lot of submissions around gaming, DeFi, NFTs and tooling.

As is typical with a hackathon, hackers were permitted to stay overnight and many enthusiastically took up that additional challenge. Most stayed up into the early hours and a number of teams did not leave the venue (choosing to sleep in a tactically chosen makeshift bed) or even sleep at all.
