Submit a hackathon

List your hackathon

Running an AI, blockchain, design, or robotics hackathon? Submit it here. Every submission is reviewed before it goes live, and we'll email you either way.

This form covers the basics needed for approval. Once you're live, we'll set up the specifics with you, individual or team-based submissions, GitHub or file uploads, single or multi-country judging, custom rules, and more.

Image

Recommended: at least 1600×900px, landscape works best. This shows in full (never cropped) on your hackathon's own page, and also generates the smaller listing thumbnail shown on the hackathons page.

Upload an image (max 3MB)

Or paste a link instead:

A Google Drive share page won't work by itself, we convert it automatically, but the file must be shared as "Anyone with the link." If the preview below doesn't load, try Imgur, Postimages, or GitHub instead.

External registration link (optional)

Leave this blank if that's fine, most hackathons don't need it. Builders register, form teams, and submit projects right here on Multichain Builders once you're live. Only fill this in if you specifically need to redirect people to sign up somewhere else first.

Anything else we should know? (optional)

Only our team sees this, it's not shown publicly. Every hackathon on the platform can be set up differently (solo GitHub submissions, team-based with join codes, multi-country judging, custom judging criteria, and more), tell us what you need and we'll configure it for you after approval.
