Sui Network Extends Hackathon Deadline to May 23

The Sui Network has issued a final reminder to Web3 developers worldwide that the deadline for submitting entries to its flagship hackathon, Sui Overflow 2025, is rapidly approaching. The deadline, which was originally set for an earlier date, has been officially extended to Friday, May 23, providing participants with a few more days to finalize and present their innovative projects.

In a tweet posted earlier today, the Sui Network addressed "buildooors" – a term affectionately used in crypto circles for developers – encouraging them to take advantage of the extension and secure their place in one of the largest decentralized development events of the year.

The Sui Overflow hackathon has become a significant event on the blockchain development calendar. Supported by the Layer 1 blockchain protocol Sui, the event invites coders, designers, and product thinkers to develop decentralized applications (dApps), tooling, infrastructure, and smart contract solutions using Sui’s Move programming language.

This year’s event is expected to be the largest yet, attracting talent from around the world. While the network has not disclosed exact submission numbers, community engagement across various platforms suggests rising interest. Sui has positioned the hackathon as a platform for discovering early-stage innovation within the ecosystem, often providing visibility to projects that may evolve into full-scale ventures.

The decision to extend the deadline to May 23 appears to have been driven by community feedback, with many developers requesting additional time to refine their submissions. With just under a week left, the message from Sui is clear: now is the time to wrap up and submit.

“Reminder: buildooors, you have until next Friday, May 23, to submit your projects for #SuiOverflow2025!” the official tweet read. Participants were also directed to sui.io/overflow for more information and submission guidelines.

Unlike corporate-sponsored hackathons with high barriers to entry, Sui Overflow is designed to be accessible and open. Teams range from independent developers to small startups and university groups. Still, the competition remains fierce. Participants will be judged on originality, technical sophistication, usability, and alignment with Sui’s core principles of performance and scalability.

The hackathon also serves as a gateway to potential funding, with previous participants going on to secure grants or VC backing. However, the Sui Network has been cautious in its messaging, focusing less on hype and more on encouraging technical creativity and sustainable project design.

With the submission window set to close in just a few days, developers aiming to make their mark in the Sui ecosystem have limited time to act. The extension offers a valuable second chance, but it’s clear that the pressure is on.

As the decentralized tech landscape continues to evolve, hackathons like Sui Overflow are increasingly seen as grassroots engines of innovation—where new ideas take shape before they make headlines.
