 In case you don't have test ada on `pre-production`, you can use the [testnet faucet](https://docs.cardano.org/cardano-testnets/tools/faucet/) to fund your wallet or the addresses above. Note that due to rate limiting, it's better to request large sums for efficiency and distribute as needed.

 If you are collaborating with another individual, exchange the verification (public) keys: `{alice,bob}-node.vk` and `{alice,bob}-hydra.vk` to ensure secure communication.
 
 Before launching the `hydra-node`, it's crucial to establish and communicate each participant's network connectivity details. This includes the IP addresses and ports where `Alice` and `Bob's` nodes will be reachable for layer 2 network interactions. For this tutorial, we're using placeholder IP addresses and ports which should be replaced with your actual network details:

 After you've prepared your transactions, the `hydra-node` will find all UTXOs associated with the funds key and create a draft of the commit transaction. You'll then sign this transaction using the funds key and submit it to the Cardano layer 1 network.
