Transaction types

There are three types of L2 transactions on zkSync: Withdraw, Execute, Deploy.

• Withdraw is used to withdraw native ERC20 tokens to L1. Please note that this type most likely will be removed after the testnet.
• Execute is used to call smart contract functions.
• Deploy is used to deploy smart contracts on zkSync.

There are also two types of transactions, related to bridging native tokens to zkSync:

• Deposit is used to move funds from an L1 account to an L2 account.
• AddToken is used to register a native ERC20 token to zkSync.
