Be Part of Kin

For Developers

More engagement, better user experiences, a new sustainable source of revenue, and an ecosystem of like minded developers to support you – that’s the Kin way. Are you ready?

What is Kin?

Simply put, Kin is money for the digital world. By building with Kin, developers (like you) can earn revenue for apps and websites in a fundamentally new way.

The vision behind Kin is to create an ecosystem of apps where value is exchanged in Kin. Value is anything that is meaningful to a user. For example, a user “liking” a post could instead tip an amount of Kin to show their appreciation for the post.

A strong Kin economy benefits all developers in the ecosystem.

Some of the apps in the Kin Ecosystem include…

Kik Messenger

100,000,000+ Installs

Madlipz

10,000,000+ Installs

Perfect365

50,000,000+ Installs

Rave

10,000,000+ Installs

A better way to earn revenue – earn more with Kin

Apps that integrate Kin are rewarded weekly by the Kin Rewards Engine. The size of the reward is based on an open-source, community-driven set of algorithms and rules that are relative to the number of active users an app has, and the total balance of Kin they hold.

*sample representation, actual payouts may vary

Kin complements other monetization methods, including advertising. For example, an app can reward Kin to its users for watching ads or sharing location data. Users can then use the Kin to purchase in-app items.

Example Use-Cases

Kin can work in many situations, and once set up, a developer can just call the function sendKin() from anywhere in their app. Below are just a few examples of Kin use-cases:

Users create exclusive groups with an entrance fee

Users tip each other for content they like

Users earn Kin and use it to buy loot in a game

Can my app earn Kin rewards?

Kin is free to integrate into any app that follows these guidelines. Kin currently supports the following SDKs:

 

Client side

Server side

How do the Kin SDKs work?

The Kin SDKs enable your users to easily…

  1. Earn (Receive currency)
  2. Spend (Send currency)

At the heart of it all, this is what your users will be doing in your app. The difference between a regular in-app currency and Kin is that Kin is a currency with actual value. The SDKs connect your app to the Kin blockchain (Solana) and handle all the complicated business in the middle, so all you have to think about is:

  1. Sending Kin
  2. Receiving Kin

Client side SDKs let your users create accounts and send Kin to each other, or to your server.

 

How do I get started?

The following resources will help you add Kin to your app.

1. Kintegrate is a developer-led site that helps you learn to quickly integrate Kin into your apps. We recommend starting here to get a broad understanding of integration.

2. The official Kin developer documentation deep dives into the client and server architecture, and covers more detailed concepts.

3. Join our Developer Discord for live tech support on any issues you are stuck on.

 

Apply for a Jumpstart Grant

Apps new to the ecosystem can apply for a grant in Kin, to help them get started and integrate into the ecosystem. The size of the grant is proportional to the size of the app joining. To learn more, send us a note detailing your application – requesting a Jumpstart Grant.
