Once you followed all of the steps, you will get the following files,

  • Deposit_data.jason that will be used to fund the validators, each with 32 ETH.
  • Keystore-m.json (per validator), an encrypted version of the validator key that can be decrypted by using the password that you have chosen in step 4.
