Yes, it’s impressive to do something on my node and see the result in an exchange (Binance).
Sparrow Wallet give so much details and features that’s great.
The first connection of Sparrow Wallet to Bitcoin Core was super long, because I have chosen the Prune block storage option (I have all the blocks in my PC since genesis block).
Sparrow Wallet is great. And of course, the best of privacy and self sovereignty is to connect your hardware wallet through your own full node.
Do you also have a local mempool.space running that connects to your own node? That guarantees the ultimate privacy when exploring the blockchain. 
Yes. I have an active mempool inside Bitcoin Knots 🪢 with significant memory usage and current number of transactions.
Ok. that's clear, every node has its own mempool.
But what I meant was this: Do you have a local tool (see my screenshot of the URL http://btcnode.local:3006/ = http://192.168.178.62:3006/) installed to retrieve information about transactions or addresses, whereby this tool interacts only with your local Bitcoin node to get this information from your locally stored blockchain? So you can track your ongoing transactions without any privacy leaks.
It doesn't work on my computer.
Do you have Umbrel, Raspiblitz, MyNode or Start9?
Those plateforms integrate mempool.space, and you can follow their guides to active mempool.space from the Web interface.
I don't have any of those devices and I don't think it's easy to install mempool.space without one of them.
Ok, I understand.
I have all this stuff running in a VirtualBox Linux VM with Umbrel installed. The additional resources are peanuts for my server.
If you cannot use a local Bitcoin Explorer, you must be aware that a public Bitcoin Explorer will log your IP and your query data, e.g. transaction ID. This can then be linked to you via a query to your ISP. If you want/need to go this route, then a VPN would be helpful to obfuscate the last step.
Yes. I already use a VPN with a location in another country.
