Registration Now Open for Sui Overflow 2025, Sui's Premier Global Hackathon

Sui Overflow, Sui's annual global hackathon, kicks off today, with teams and individuals now able to register. The hackathon officially runs for eight weeks, from April 1 to May 25, with the winners announced late May. Four teams will emerge from each of the competition's eight tracks, winning prizes ranging from $30,000 to $7,500. In addition, 10 university teams will each win $2,500 and the community will vote and award 10 projects $2,500 each.

Last year's Sui Overflow hackathon saw 352 project submissions with a total of 32 winners in its eight tracks. Sui Overflow 2025 offers completely new tracks reflecting the rapid pace of development on Sui and new areas of interest. In addition, the advent of Walrus' decentralized storage adds great new possibilities for projects, and participants are urged to use Sui and Walrus as much as possible. Along with prizes within tracks, Sui Overflow 2025 includes community voting and recognition of university teams.
