◦ NFT marketplaces

Participation Rules

• You can submit as many projects as you like.
• Each project may be submitted by an individual or a group of participants.
• Different projects from the same participant(s) can be eligible for different prizes.
• Projects must run on the Xahau Mainnet.
• Each project must be accessible online, so that both judges and the public can use or view it.
◦ This avoids the need for judges to install or configure projects locally, and reduces the risk of unexpected errors or participant assistance being required.
• Each submission must include basic documentation to help others understand the project.
◦ Optionally, you can also include multimedia material (videos, slides, demos, etc.) to better explain your work.
• AI tools may be used both for development and documentation.
• If your project uses Hooks, the Hook code must be open source, so that it can be audited for safety and serve as a learning resource for the community. You must attach their C code in your submission along with the hook hash. Check the “Submission Format” section.
• Projects that clearly offer regulated financial services or that target illegal activities are not eligible.
• To be evaluated by the judges, you must include your submission with a PR as indicated in the “Submission Format” section.
• Once your submission PR has been created, post a tweet on X about your project, tagging @XahauNetwork, to announce that you’ve participated in the Xahau Dev Contest.

Evaluation Criteria

When reviewing submissions, judges will especially value:

• Originality and creativity of the idea.
• Absence of existing competitors providing the same service on Xahau Mainnet prior to the contest.
• Impact and usefulness for end users (individuals, businesses, or public sector).
• Quality of execution (stability, documentation, user experience).
• Use of Hooks (Smart Contracts on Xahau).

Submission Format

Each project must include a folder and at least a submission file inside submissions directory of this repository. The file and directory must be named with your GitHub username followed by the project name, separated by an underscore, and using the .md extension for the file.

Example: submissions/GitHubName_ProjectName/GitHubName_ProjectName.md

The file should contain the following fields:

• Project Title
• Brief Description
• Participants (names or nicknames)
• Participants’ Social Media
• Contact Email
• Link to the Online Project
• Xahau Address to receive the prize in case of winning
• Link to Documentation
• Hooks code in C and matching hash (in case your project uses one or more, to confirm it’s safe, you should add .c files in your submission folder)
• Hooks account of the project (to confirm you are using the hooks previously provided for this project)
• Link to Project’s Repository (optional)
• Other Links (optional, e.g., demo video, presentation, slides)

A template directory and file are available in the repository folder, which participants can use to fill in their project details.
