Code For Stacks
Earn for building on Bitcoin
As more of you are starting to explore the world of building on Bitcoin, we want to support you in your journey. In addition to numerous free learning opportunities both virtual and in-person, we want there to be an opportunity for you to earn every.single.month.

All you have to do is code.
You can win just for keeping up with your project!
Code, Commit, Earn
10,000+ STX up for grabs monthly!
Earn a reward every month you submit valid PRs that move your Stacks project forward. You can work on any project you like, or contribute to others! You'll earn STX from a prize pool of 10,000 STX every month, with more available for those who are shipping consistently! Winners are drawn at random each month from the pool of valid entries.
Code
Each month, submit Github PR links showing the progress you've made on your project or where you've contributed.
Review
From there, our team takes over reviewing your code. Just make sure it's a meaningful PR and that the PR is publicly available!
Earn
All valid entries are drawn from, with one developer earning a 2500 STX jackpot and 75 others earning 100 STX. Plus, those that ship consecutive months start earning every month no matter what thanks to Streaks!

How Does It Work?
Keep on coding
To have a shot each month, you just need to work on your project. We're looking for a meaningful pull request via Github that meets one or more of the following criteria:

  • Add a new UI element or page
  • Fix a bug
  • Add a new Clarity contract
  • Add meaningful* new Clarity contract functionality
  • Optimize a contract function
  • Enhance the security of your contract
  • Add a test suite
  • Meaningful* refactor that enhances functionality or performance
  • Meaningful* UI enhancement

Code must be open-sourced and publicly available via Github. You receive one entry for every valid PR, limited to one PR per repository/project. Total entries are unlimited, but to receive multiple entries you must submit valid PRs from distinct projects.

Drawing for prizes
To ensure as many different developers have a good chance of winning each month, the first drawing is done by taking one PR per developer. If there are remaining slots from the 75, we draw again at random from the entire set of entries.
+Boosters
There are currently two types of boosters in the program:

  1. Streaks (Ongoing): A big part of the Code4STX ethos is encouraging consistency in shipping code. To reward those who ship regularly, we now have Streaks, which allow you to start earning rewards every single month, even if you are not drawn.
  2. Special Events (Limited Time): You can earn extra entries and/or prizes by participating in special events. These opportunities will be shared on social and via email to active program participants.
Just point us to your new code, we do the rest!
How to Submit
Complete onboarding
Submit the brief onboarding form, telling us a little bit about yourself
Do the work
Code like crazy and move your project forward, we just need to see meaningful progress! Your app doesn't have to be live to be eligible but you should be progressing toward a launch.
Provide Proof of Work
Show us what you accomplished! Use the 'Submit your work' button below to submit your code commits from the month.
Every month is a new shot to win
Schedule
Keep on coding
Code is due at 11:59pm ET on the last day of each month. Any entries received after that point will be added to the pool for the next period.

Prizes are awarded by the 15th of the following month, or the next business day if the 15th falls on a weekend or holiday.

There is no advantage to submitting early and the time of your submission within the month does not play a factor in how prizes are awarded.

FAQ
  • Question:
    Does my application have to be 100% Stacks-based?
    Answer:
    No, but it should leverage Stacks in a significant way. This will be up to the discretion of the reviewers, but you can get in touch if you're unsure. A helpful lens could be: "Would this application function and/or be able to provide the same utility to its intended user without Stacks components?". If the answer is yes, it would be difficult to qualify for this campaign.
  • Question:
    Does my application have to be live?
    Answer:
    No, but it should be heading for a launch eventually. We understand things take time and we want to reward you along the way for building. Reviewers have the discretion to eliminate an entry if a path toward being live and available to users is unclear or if they come to believe a developer has no intent to launch.
  • Question:
    Does my application have to be brand new for this campaign?
    Answer:
    No, if you are already building something you can point us toward that repo in your onboarding form. Each month you simply need to show progress for said project, it doesn't matter when you started it.
  • Question:
    What if my project has raised money?
    Answer:
    If you have raised more than $500,000 related to your project, you are not eligible. This program is intended to fund independent developers and small teams as they get started in the Stacks ecosystem.
  • Question:
    What if I stop coding or forget to submit for a month?
    Answer:
    It's no problem, but you will lose any multiplier you're earning from the Consistency Booster. To get back in, simply submit your code and you will be back in the prize pool for the month you submitted in.
  • Question:
    Can I use multiple emails or identities to participate?
    Answer:
    No! Ultimately, this is just a headache for both of us as entries are unlimited anyway. No method of participating under different identities will be tolerated, thank you for understanding.

    Further, all entrants must KYC to receive prizes. If you sign up with multiple emails, we’ll find out at the KYC stage before payment. If you do this, we will remove your eligibility. You may not use someone else’s identity to collect additional prizes and we maintain the discretion to disqualify you if we suspect you’re doing this, even without definitive proof. Please play nice and be respectful to this amazing cohort of developers :).
  • Question:
    Do I need to make any purchases to be eligible?
    Answer:
    Absolutely not. Entry is free, along with all the education you might need to get to the point where you're able to participate. The only requirement to enter is to produce meaningful code each month. You can review what constitutes eligible code above. Our team reserves full discretion to disqualify entries and there will be no appeals process. Put simply, if we feel you're trying to cheat the system or spirit of the contest, we can disqualify you. Don't make us do it ;)
  • Question:
    I have another question
    Answer:
    Great, you can get in touch with us at community@stacks.org.
