Case Study: Click

Click has integrated Zyfi's paymaster solution into their app, fully sponsoring all transactions.

Click is a revolutionary application in the digital media ecosystem, offering a "trust network" solution that enables creators and consumers to easily authenticate photo and video content. Using ZKsync blockchain technology, Click combats misinformation by providing a simple and intuitive platform to verify the authenticity of creations on-chain.

To enhance the user experience, Click partnered with Zyfi to eliminate barriers related to gas fees.

Gas Fees Management

Managing gas fees is a recurring challenge for blockchain-based applications, especially those aimed at the general public. These fees can create a significant barrier for users, making it harder to adopt and regularly use applications like Click, which seeks to democratize content authentication.

Click's goal was to provide a seamless user experience where users could authenticate their content without worrying about transaction fees.

Implementation of Zyfi

To address this, Click integrated Zyfi’s sponsored paymaster on ZKsync Era. This partnership allows users to authenticate their content without incurring any transaction fees.

With Zyfi’s solution:

• Users can register their creations without realizing they’re signing a blockchain transaction.

• Click eliminates technological barriers, delivering an accessible and smooth experience for all users.

UX/UI Implementation

The integration process followed a structured approach:

1. Define On-Chain Actions and UI Improvements: The team focused on fully sponsoring transactions to offer the best user experience—no need to think about gas fees.

2. API Integration: The API was integrated into the front end in just one day.

3. Zero UI Adjustments: Since the transactions are gasless, no additional UI changes were required, as users are unaware they’re signing a blockchain transaction.

Total time: 1 development day. 🎉

Results

Click attracted many users after the Zyfi integration, sponsoring over 53,000 transactions as of December 11, 2024, with an average of 800 sponsored transactions per day.
