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.

All is powered by an API that abstracts complexities away from protocols, so that they can focus on building their product. Zyfi is integrated by many dApps in the ecosystem, e.g. ZeroLend (Supply & Borrow), Gravita (CDP), Increment Fi (Perp) and zkMarkets ( NFT marketplace) - with more in the pipeline.

Zyfi has also partnered with major NFT collections on zkSync, offering a gasless experience and utility for their holders. On top of the paymaster service, Zyfi offers a gasless portal to the ecosystem, where users can experience the power of native AA: they can swap at the best rates, send tokens without having ETH, or submit custom paymaster transaction to interact with protocols that don't offer a paymaster solution yet.
