FAQ
Sui Overflow 2025 is a global online hackathon where developers, builders, and innovators come together to create on the Sui blockchain. Participants will have the chance to build projects using Sui and the Move programming language while competing for prizes, mentorship, and exclusive developer initiatives.
Sui Overflow 2025 is a great opportunity to work closely with Sui Foundation, connect with top developers, and gain exposure to investors and mentors. There are a variety of prizes, and projects may also get invited to further developer initiatives.
Anyone is welcome to participate in Sui Overflow 2025! Whether you're a seasoned Web3 developer, a designer, or just starting to explore blockchain, you’re welcome to join. There are no experience requirements—just bring your ideas and motivation.
All technical questions should be asked in the Sui Hackathons Discord Server, where mentors and team members will be available to help.
Registration is open now at this link.
No. Sui Overflow is an online hackathon where registration, development, and assessment are all conducted virtually. There will be related in-person events, like developer meetups and workshops, but these are optional and attendance will not affect the assessment process.
During the registration process, you can indicate if you’re looking for a team to be added to our team directory, where participants can find teammates to build with. Another place to search is in the official Sui Overflow Discord server. We will also host some team-matching events, which we’ll announce in the Discord server.
There are many developer resources available to help you get started with Sui and Move. Access the Sui developer docs, explore developer tools and resources on the Sui developer portal, or take a self-paced intro course to Move to get started.
To keep things fair, projects should only be started after the official hackathon start date February 12, 2025. The submission period officially opens on April 1, 2025, giving teams time to develop and refine their projects.
You'll need to pick the track that best represents your project. Judges will evaluate submissions based on the chosen track, so go with the one that aligns best with your idea.
