As part of this year’s Meridian, the free virtual Stellar blockchain conference, the Stellar Development Foundation is sponsoring a hackathon that challenges old hands and newcomers alike to build something showcasing at least one of Stellar's new features.

In addition to $12,000 worth of XLM in prizes, contestants will compete for bragging rights and glory: the top 5 projects will be featured on the event website, get feedback from some of the top brass at SDF, and be evaluated and voted on by the wide world of Meridian attendees.  Build something cool, try something new, get rewarded, and get your name out there! 

The Challenge

Four new features were added to the Stellar protocol in 2020, and your mission, should you choose to accept it, is to build a project on the testnet that incorporates at least one of them.  They are:

As long as you implement at least one of those features, you can build anything you'd like, so get creative!  These features are new to everyone — several aren't even available on the public network yet — and we're interested in seeing intuitive and user-friendly products that explore the possibilities they open up.  

To find out more, check the Resources tab, which points to high-level explainers and nuts-and-bolts documentation of the new features, and offers tips and links to help you get started if you're new to Stellar.    


You must be at least 18 years of age to participate in the Meridian Hackathon unless your country's minimum age for receiving a cryptocurrency award is older, in which case you must meet the minimum age applicable in your jurisdiction.

Unfortunately, if you’re a national or resident of Cuba, Iran, North Korea, Syria, Sudan, or the region of Crimea, we are unable to send you any lumens. Additionally, we may be unable to send lumens to winners in countries where local law makes it unlawful for residents to hold or receive cryptocurrencies. Please note: we currently cannot send lumens to residents of the US states of Alabama, New York, Georgia, Connecticut, New Mexico, Hawaii, Vermont, and Washington.

[UPDATED 9/28/2020]


We are looking for a functional project built on the Stellar testnet that implements at least one of the four new protocol features introduced in 2020.

To enter, complete all of the required fields on the “Enter a Submission” page by November 8, and make sure it's clear which new feature (or features) you've implemented, and why you chose to implement it (or them).  

All entries must:

  • Share a link to the Github repo. We want to evaluate the code, understand your thought process, and assess your implementation.
  • Share a link to a video that clearly demonstrates the project’s features and functionality. The video should:
    • Be no longer than 3 minutes;
    • Have a 16:9 ratio (e.g. 1920x1080px);
    • Be uploaded on YouTube or Vimeo as unlisted.
