Announcing the Sui Overflow 2025 Hackathon Winners
The latest Sui annual hackathon was a huge success, with over 40 innovative projects among the winners.
Editors' note: This article has been updated to correct a mistake in the Programmable Storage section.
The Sui Overflow Hackathon 2025 concluded last week, with 36 winners emerging in nine tracks from the 599 total project submissions. In addition, 10 winners were chosen from the University group. The Entertainment and Culture track attracted the most submissions, not too surprising as Sui is the only blockchain built for mass adoption. AI proved the second most popular track, showing Sui's ability to host the most cutting edge technology.
Project builders, who originated from 85 countries, began registering in February of this year. The official build period ran from April 1 to May 25, followed by shortlisting of project submissions, demonstration days, then judging and community voting. Four teams emerged from each of the competition's nine tracks, winning prizes ranging from $30,000 to $7,500. In addition, the winning university teams came away with $2,500 each.

Community voting and award
Sui Overflow 2025 community voting took place the week after Demo Day, between June 14 and June 20. Eligible community voters were able to vote for the projects they believe should win across the nine official Sui Overflow 2025 tracks by picking one favorite project in each track. The awards given in this category were for those community voters whose selections most consistently coincided with the track winners, reflecting technical discernment and overall alignment with expert judges.
The community voting results were used in the calculation of the project rankings for each primary track, by assigning points proportional to the number of votes each project received out of the total number of votes in a given track.
The voters who came closest to getting all nine track winners correct won the Community Award for their foresight and discernment. Out of 195,029 number of total votes, the closest votes got seven out of nine track winners correct, and there were 28 winning votes in this category.
Please check the Community Vote page to see the winning voter wallet addresses and claim the Community Award.
