user6527: I am trying to figure out transactions without receiver address or same receiver and sender address .
What do these transactions mean ? I also see a deposit in the later part of the transaction. Can someone break the transactions down for me . Sharing some sample transaction hashes .

user1897: The first transaction looks like it is intended to "defragment" two utxos into one, no idea why...
The other transactions are stake pool registration transactions. The pool deposit of 500 Ada is being submitted in these transactions.
The Cardano Blockchain Explorer clearly mentions this 500 Ada as a deposit. View your second transaction here
In case you're wondering where the 500 Ada goes to, no... it doesn't go to the treasury... instead it seems to be recorded on the ledger itself as a deposit. This can be returned later on to the stake pool if and when it is deregistered. Read more here
To find out more about this process, refer to the corresponding documentation
Hope this helps!
