+This command will bridge 1 ETH to `0x36615cf349d7f6344891b1e7ca7c72883f5dc049`.

-For testing purposes, we'll use one of the rich wallets as both the sender and recipient:
-
-```shell
-? Amount to deposit 10
-? Private key of the sender 0x7726827caac94a7f9e1b160f7ea819f172f7b6f9d2a97f992c38edeab82d4110

-To see that it worked, let's check the balance of that address on `prividium_chain`:
-
-```bash
-npx zksync-cli wallet balance \
---address 0x36615Cf349d7F6344891B1e7CA7C72883F5dc049 \
---rpc http://localhost:3050

-Now this address has ETH available on `prividium_chain` to use for testing.
