In the following two scenarios, transactions initiated by the zkSync wallet cost higher fees than the average.

Scenario 1: The first transaction initiated by the zkSync wallet

The first transaction initiated by the zkSync wallet includes three parts: generate signer key, set account public key, and transfer signature, so fees for the first transaction will be relatively higher. But the fee for subsequent transfers will return to the normal level.

Scenario 2: Transfer tokens to an inactive zkSync wallet address

When transferring tokens to an inactive zkSync wallet address, you need to pay an extra activation fee, so the fee will be relatively higher.
