<figure><img src="/files/OF4FvVDStedFvnfp9bdJ" alt=""><figcaption></figcaption></figure>

[Ebisu’s Bay](https://www.ebisusbay.com/) is an innovative platform merging NFT, DEX and token trading with immersive GameFi experiences. As the first NFT marketplace and DEX on [Cronos zkEVM](https://docs.cronos.org/cronos-zkevm/cronos-zkevm), it stands out with community governance and enriched features, enabling users to engage in battles and strategic gameplay while trading digital assets. However, as with many blockchain applications, gas fees can negatively impact the user experience.

## Gas Fees Management

Gas fees are a recurring challenge in the blockchain ecosystem, particularly for users unfamiliar with the system or those aiming to maximize their investments. These fees often act as a barrier to adoption and accessibility, limiting user engagement on platforms like Ebisu’s Bay.

A seamless solution was needed, especially in a gaming, NFT, and trading environment.

## Implementation of Zyfi

By leveraging the ZK Stack with native Account Abstraction, Ebisu’s Bay integrated Zyfi, enabling it to cover gas fees for users. Transactions are now conducted without direct fees, and users can even pay with a variety of tokens. This significantly improves the user experience by making transactions transparent and hassle-free.

**With Zyfi’s Solution:**

* Ebisu’s Bay users can swap using **5+ ERC-20 tokens as gas.**
* Transactions are free when users select **FRTN** (Ebisu’s Bay’s platform token) as the gas fee token.

## **UX/UI Implementation**

The integration process followed a structured approach:

1. **Defining On-Chain Actions and UI Improvements:**\
   The team focused on sponsoring transactions for token holders and allowing payments with 5+ tokens as gas.
2. **API Integration:**\
   The API was seamlessly integrated into the front end in just one day.
3. **UI Adjustments:**\
   A dropdown menu was added to the swap card to display available gas fee tokens.

**Total Time:** 1.5 development days 🎉

## Results

Ebisu's Bay attracted many users after the Zyfi integration, sponsoring over **5,430 transactions** as of December 20, 2024, with an average of 100 sponsored transactions per day.

## Conclusion

The integration of Zyfi with Ebisu's Bay represents not just a technological breakthrough but also a revolution in user experience within the on-chain authentification space.
