Mastering zkSync’s Paymaster Feature

INTRODUCTION

ZkSync continues to advance in the mission to scale ethereum, and at the forefront of this progress lies the pivotal Paymaster feature.

A paymaster is like a virtual wallet that can pay for actions on behalf of its users. It’s like having a digital assistant that decides whether to make a payment based on certain rules. For example, it can let users perform actions for free or use a specific type of cryptocurrency
The introduction of the paymaster feature was part of an enhancement initiative known as Account Abstraction EIP. While zkSync inherently supports this initiative, notable modifications have been made to its implementation.

In their customized approach, the primary focus is on ensuring user safety, providing seamless experiences, granting flexibility to developers, and preemptively thwarting potential attacks that could disrupt the system. This strategy aims to create a secure and user-friendly environment while fostering innovation and resilience within their ecosystem.

Protocols with Paymaster Compatibility

Paymaster is designed with a focus on developer flexibility, it empowers protocols to construct the feature in a way that aligns with their specific functionalities. For instance, within a DEX or bridge on zkSync, users can process transactions using either USDT, USDC, or the native token of the protocol.
