Zyfi is a Paymaster-as-a-Service that simplifies gas fee management for dApps on the zkSync ecosystem, allowing users to pay with any ERC-20 token or letting dApps sponsor transaction costs. Powered by an API that abstracts complexities, Zyfi integrates with many dApps to offer gasless transactions and a seamless user experience. By leveraging zkSync’s native account abstraction, Zyfi facilitates gasless transactions directly from Externally Owned Accounts (EOAs), enhancing usability and adoption.
