title_body: Is there a maximum amount of ADA I can send in one transaction? This question is related to one of my previous questions: Is there a minimum amount of ADA I can send in a transaction?
  I wonder, if there is a minimum amount of ADA I can send in one transaction, is there a maximum amount too? Or would it theoretically be possible to send all 45B ADA in one transaction (if someone would own all ADA there is)?
upvoted_answer: The limit amount of output ADA is specified as Word64 which is an 64-bit unsigned integer, therefore the maximum output is 18 446 744 073 709 551 615 lovelaces in the current implementation.
  So, sending all 45 billion of ADA is theoretically possible.
