The paymaster feature was first included as an extension of the Account Abstraction EIP (EIP-4337). zkSync supports AA natively, although our implementation has some core differences from the original proposal. Read more about them here: https://t.co/lttlQQdb0e.

A paymaster is a smart contract that can pay for transactions for its users, executing any logic to decide whether it should forward a transaction. For example, developers can allow users to run transactions for free or pay in your application's ERC-20 token instead.
2/8
The main goal of our customized approach is to keep the following properties:
• Security and good UX for the user
• Flexibility for the paymasters and developers
• DoS safety

Paymasters implement our IPaymaster interface with the following methods:
• validateAndPayForPaymasterTransaction: decides if the paymaster approves paying for the transaction
• postOp: called after the transaction is executed (ex: to refund sender for unused ergs)

Security audits are an important part of securing zkSync 2.0, but we're not stopping there. We have additional security measures planned over the next several months, including bug bounties, contests, and hackathons.

As a principles-led team, security dictates everything that we do at zkSync. We’re committed to a zero-compromise approach to security for zkSync 2.0. Continuous real-time monitoring goes above and beyond one-time audits to provide full protection and peace of mind.
