Join Us For The First Community Smart Contract Challenge With $50,000 In Prizes!

We are thrilled to collaborate with the Stellar Development Foundation to introduce the community to blockchain technology.

Running through August 18, the Build Better on Stellar: Smart Contract Challenge provides an opportunity for web devs to learn all about decentralization, wallets, consensus, interoperability, and all the other lingo you may have heard floating around but never quite understood. This is your signal to dive in and unlock those a-ha moments!

We’ll share all the resources you need to learn the fundamentals, and you’ll come out of the challenge knowing how to build with Soroban, Stellar’s smart contract platform designed for scale and sensibility.

We have two prompts for this challenge, but six ways to win. Did we mention the $50,000 prize pool? And a free trip to London to attend the Meridian Conference?! Our biggest offering to-date, thanks to the generous Stellar Development Foundation.

Ready to get learning and building? Read on to learn about the prompts and how to get started.

Our Prompts

Build a dApp

Build a decentralized app (dApp) that leverages one or more Stellar smart contracts. The main requirement is that users should be able to interact with the application. Other than that, you are free to build whatever you want!

Prize Categories

In addition to our overall Build a dApp winner, we have two additional prize categories you could win for this prompt:

Glorious Game: Awarded to a top game dApp
Super Sustainable: Awarded to a top dApp that focuses on real-world positive impact

Here is the submission template for anyone that wants to jump right in, but please review all challenge and prompt-specific rules on the official challenge page before submitting.

In addition to our overall Create a Tutorial winner, we have two additional prize categories you could win for this prompt:

Wonderfully Written: Awarded to a top written tutorial
Vivid Video: Awarded to a top video tutorial

How To Submit Your Project

At minimum, you will need to take the following steps to submit a valid entry:

Fill out this form on the Stellar website. Make sure the email address you sign up with matches the email address associated with your DEV account so we can verify your submission.
Publish a post using the submission template associated with each prompt.

All participation guidelines (i.e. judging criteria, links to contest rules, etc) can be found on the official challenge page so be sure to review that information thoroughly before submitting.

Getting Started

We know it can be a bit intimidating to jump into web3 and blockchain, so the Stellar team has published a companion guide that covers all the topics you need to get started:

Additionally, we encourage all participants to join the dev-hack channel in the Stellar Dev Discord, a community server for asking questions and meeting the community of developers building with Stellar.

Need Inspiration?

Below are a few ideas for both prompts to get your creative juices flowing.

Your smart contract dApp could be related to:

A game where players interact on-chain to compete against each other
A public goods application where interactions with the dApp could result in real-world positive impact.
A DAO or governance-related dApp
Identity Tooling
Financial services, like a wallet or payment dApp

Your tutorial could focus on:

We can’t wait to see what you come up with.
