Stellar Build Challenge

Move Money Faster, Win Lumens from

The Stellar Build Challenge is an ongoing program to reward
innovation and development in the Stellar ecosystem.

Submit your project by November 15th, 2017

Submit Your Project

Four times a year, the panel of judges from the Stellar community recognize solid craftsmanship and innovation in the ecosystem:


Johan Stén

Eno Han

Tim Akinbo

Christian Rudder

James Gong

2017 Dates

Submissions for each round now must be done at least two weeks prior to judging. You must announce your project on to get feedback from SDF, the judges and most importantly the Stellar community. This will give you time to improve your project prior to final judging.

Two weeks after the announcement deadline, the judges will be allotted a set amount of lumens to award per category as they see fit. Judges aim for announcing winners within two weeks of submissions closing.

If you live in a restricted area—any country on the U.S. sanctions list, as well as the states of NY, CT, or NH—regulations prevent us from sending you lumens. Unfortunately, therefore, residents of restricted areas are not eligible for an award.

All participants will retain the intellectual property associated with their submission.

Guidelines and Suggestions for Submissions

  • Judges will be prioritizing submissions that are polished, complete and fully functional.
  • Submissions must be live and available somewhere so people can use them.
  • You can submit your application even if you entered a prior build challenges but judges will be looking to see that improvements have been made.
  • Always helpful to provide documentation with your submission!
  • Bonus points will be awarded the more people are using your service.

We highly value your participation in the Build Challenge so we highly recommended sharing your project with the community prior to hitting “submit”. Here are some good places to get feedback.


APPLICATIONS: 2,000,000 lumens

What types of applications we are looking for:

WALLETS: 1,500,000 lumens

There are some good wallets with base functionality now. We are wanting to see:

  • Continued usability improvements and polish to what is there now
  • Wallets with multiple accounts
  • Good design
  • Sending lumens to any email address
  • Other features that allow easy onboarding and increased virality

TRADING TOOLS: 1,700,000 lumens

We are looking for graphs and moving toward this idea of a distributed exchange.

REMITTANCE APP: 600,000 lumens

We are awarding lumens for a remittance app that allows end users to easily send money to Philippines, Nigeria, Kenya or other places that are now connected via Stellar.

Must allow users to somehow get money from their either their bank account, agents, credit cards, into the app so they can send without getting lumens off an exchange. The user should probably not even know they are using Stellar.

ISSUING ICO or TOKENS: 600,000 lumens

This category is for issuing a novel token,coin, or asset on Stellar. Stellar is built for this! Why people are doing this on other platforms we just don’t understand.


They are three fairly active forums now. Any new entrant would have to be an improvement over these.
