What is RFX?

After months of work on ZKsync Testnet, RFX is about to launch the first perp DEX with programmable liquidity and native pair trading on ZKsync Era (mainnet).

Built for better capital efficiency, minimized liquidity fragmentation, and streamlined execution, RFX helps traders identify and express their edge.

Solving Gas Fees Issues to enhance UX

Managing gas fees is a common challenge for blockchain and on-chain trading apps. Thanks to the ZK Stack, the RFX project, available on the ZKsync Era chain, can benefit from features like native account abstraction and paymasters.

Zyfi offers a paymaster-as-a-service, allowing RFX to sponsor fees for users on these following on-chainactions:

1. Making trades — approving and executing contracts

2. Adding liquidity — approving and executing contracts for LP deposits

3. Claiming rewards

4. Referrals — joining referral code, editing referral code, creating new referral code

From the user’s perspective, there’s no need to worry about gas fees anymore on RFX app.

Implementation Process

RFX devs shared: ‘The integration process was smooth overall, with comprehensive support from Zyfi. While there were a few challenges integrating the one-click trading feature, they were resolved efficiently.’

At Zyfi, we’re focused on creating top-tier on-chain UX, especially on ZKsync Era and ZK chains. If you’re a Dapp on ZKsync, we’d love to help you too, offering gas grants and easy integration. Check our docs here: https://docs.zyfi.org/

The Paymaster Revolution continues ⛽️
