The Kin Crypto Challenge:

Take the Kin Crypto Challenge and build creative and addictive peer-to-peer Kin experiences into your mobile app or game. Take your mobile app to the next level when you integrate the Kin cryptocurrency into it with addictive Kin experiences that encourage social, peer-to-peer interaction, community building, and increased retention.

What’s possible with Kin

Kin helps you create amazing peer-to-peer experiences in your app. Kin is a digital currency, it's money, but it's built in a way that makes it really easy to send micro-transactions between users. You can think of Kin as a way for users to micro-gift each other in your app, kind of like a digital high-five. They can also use it to pay for digital content in your apps and games.

How to rise to the challenge

Developers participating in this challenge are required to integrate the Kin SDK into their platform and go live on either Google Play or the App Store. Each app has to incorporate at least one social feature with Kin. This can be a leaderboard, group challenges sponsored in Kin, user-to-user tipping in Kin, or anything else you can think of.
