[ Business context ]

Chingari aimed to establish a creator economy where users could earn genuine value for their in-app activities.

To make this vision possible, they needed more than just a rewards feature. They needed an entire blockchain-powered ecosystem, including a custom cryptocurrency (GARI), a secure mobile cryptocurrency wallet, a real-time token rewards system, and a scalable SDK for other applications.

Delivering this vision demanded deep blockchain expertise and mobile security know-how, which the Onix team provided.

[ Results ]

The launch of the GARI cryptocurrency and wallet transformed Chingari from a traditional social platform into a fully functional, secure cryptocurrency ecosystem.

With a secure in-app wallet, users can store tokens, track activity, and sign blockchain transactions all within the app.

The mining mechanics increased user engagement by rewarding meaningful participation, while the seamless Solana integration ensured fast and low-cost operations, even under heavy traffic.

The standalone GARI SDK opened the door for new partnerships, allowing other apps to integrate the token and reward engine.

This expanded Chingari’s ecosystem beyond its own platform and created new monetization channels.
