I'm trying to find a master public key (I believe this is the xPub) of an electrum wallet I no longer have access to. This is ok, I've moved all BTC from there. The thing is, I need the public key to keep track of my transactions.
Given the single wallet address I can find all the transactions on blockchain.com, but I'm not able to understand where some of the transactions sent BTC to. Is this possible?
For example, this addresses latest transaction: https://www.blockchain.com/btc/address/3DnByQ6HVhcFLj452uxWDZ7ZefSxQ6SsWE states that 0.01403834 was sent somewhere, but it then lists 100's of addresses.
Which one of these was the 0.01403834 sent to?
To recap, I need a way to know either
the xPub key from a single wallet address OR
be able to read all transactions on an address on something like blockchain.com - That said this doesn't cover all the transactions on that wallet, it only covers transactions at that single address correct? So this leads me to believe I still need the xPub.
