What is Zyfi ?

Zyfi is a Paymaster-as-a-Service that focuses on flexibility and ease of integration. It was created as a way to accelerate the adoption of paymasters in the zkSync ecosystem. DApps can either propose to their users to pay with any ERC-20 traded on zkSync (currently more than 80), or decide to sponsor part or all of the transaction gas cost with their own custom logic.

Here are some reasons to integrate Zyfi's paymasters:

✅ Easy to integrate

The three different solutions developed by Zyfi are designed to be simple to implement. All tutorials are available in the documentation, and it typically takes the tech team less than a day to integrate the solution.

📈 Expand Your Audience, Boost Engagement, Retention, and Volume

The flexibility in gas fee payments and fee sponsorships contribute directly to higher transaction volumes and sustained user engagement. Native AA on zkSync is designed to appeal to a broad user base.

👍 Transparent Fee Structure

Zyfi currently charges no fees on their paymasters contracts. The precise paymaster allowance system optimizes gas expenditures and builds trust with your users. Gas fee refunds on ZKsync are processed in the same ERC-20 token used for payment.

🔓 Focus on Security

Integrating Zyfi ensures a foundation of trust and security with smart contracts that are audited, immutable, and verified. This enhances the overall credibility of your platform and reassures users about the safety of their transactions.
