# Paymaster The SyncSwap Paymaster is a low-level transaction service powered by the Native Account Abstraction (AA) of ZKsync. Integrated seamlessly with the SyncSwap app, the Paymaster removes the traditional barrier of requiring native ETH for transaction fees #### Pay Gas In *Any Token* Allows users to pay gas fees using multiple ERC20 tokens (such as USDC or USDT), which is particularly beneficial for users transacting primarily in stablecoins #### *Gas-Free* Swaps Enables entirely gas-free swaps under specific circumstances, such as when sponsored by the protocol or ecosystem partners to enhance user onboarding --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
