A: The basic function is similar for users to transfer certain assets to other users. In L1 wallet, you enter L1 address to make transactions, while in L2, you could only transfer to L2 address with zecrey suffix. And in L1 users could only transfer to one address at one time in L1, but in L2 one-to-many transfer, you could transfer to more than one receiver. What is more, all L2 transactions are under Zecrey's built-in privacy protection.
