 #### Connecting to the zkSync Network
 
 To connect to the zkSync network, you need to provide the URL of the zkSync node. The localnet runs both an *Ethereum* node (L1) on port `8545` and an *Era* node (L2) on port `3050`. You can connect to the zkSync Era network using the following code:

 To create a payment transaction, you need to provide the sender's address, the receiver's address, and the amount to transfer. You can create a payment transaction using the following code:
