 **NOTE**: On a private test network, the deployment of smart contracts is feasible on both L1 and L2 networks. However, the transfer of tokens between these networks is not possible as it requires the operation of the Sequencer.
 
 A private test L1 and L2 networks are established using the `anvil` tool, and the smart contracts are deployed using the `forge script` tool. To run a private networks and deploy the smart contracts, follow these steps:
-1. Create `.env` file and set the vars `PRIVATE_KEY`, `L1_RPC_URL`, `L1_FORK_RPC_URL`, `L2_RPC_URL`, `L2_FORK_RPC_URL`, `L1_STANDARD_BRIDGE_ADDR` and `TEST_NETWORK_MNEMONIC`. You can copy and rename the `.env.example` file if the default values provided in `.env.example` are satisfactory.
+1. Create `.env` file and set the vars `PRIVATE_KEY`, `L1_RPC_URL`, `L1_FORK_RPC_URL`, `L2_RPC_URL`, `L2_FORK_RPC_URL`, `L1_STANDARD_BRIDGE_ADDR` and `TEST_NETWORK_MNEMONIC`. You can copy and rename the `.env.example` file if the default values provided in `.env.example` are satisfactory. `L1_RPC_URL` should be set to `http://127.0.0.1:8545` and `L2_RPC_URL` should be set to `http://127.0.0.1:8546` if no changes are made in the `./runL1TestNetwork.sh` or `./runL2TestNetwork.sh` script files.
 2. Navigate to the `script` directory.
 3. To create and launch a private test L1 network, execute the script: `./runL1TestNetwork.sh`
 4. To create and launch a private test L2 network, execute the script: `./runL2TestNetwork.sh`
