Electrum question on IP address

[coinrifft]

Given this example:

Login to Electrum with my local and clear net ip address. Then suddenly, I uses VPN, will Electrum servers could theoretically link my wallet into 2 different ip addresses? Thus affecting my privacy as switching mid usage and create a link or trail ? (same addresses queried from two IPs).

[Abdussamad]

Yes

Let me start with you can hide your IP addresses but you cannot hide you wallet addresses.

The thing is once you connect to a node ( or electrum servers), it sees all bitcoin addresses and can connect them together because connecting to it was like giving them access to this informations as such they can say that so and so addresses belongs to this wallet and also possibly they will connect the IP address to it.

You can then choose to actually use a different IP addresses through the help of Tor and VPN likes but you see those addresses as long its other people’s server you’re using then they can connect your wallet addresses together.

So the answer is using tor which I am sure of avoids the linking of your IP address to your bitcoin address.

Yes

No, this will not affect your privacy


To prevent this linking, you have to use Tor with Electrum

It does. Relying on public server or node means you trusted them, your privacy is at risk if you are using them more often, worse when you don't know how to handle privacy properly.

It will be good we differentiate between privacy and anonymity. If you are not running your own node, you can use Tor on SPV wallets to have anonymity, but not that you have privacy. If you want privacy, run your own node or your own Electrum server with Tor. Using Tor with SPV wallets will only let you be anonymous but not private.

It is better you use VPN on a device that you disable ISPN direction internet in a way that if you do not connect to the VPN, the device will not go online. I still do not prefer this method.

What I prefer is to set the proxy to Tor connection. In this case, without Tor connection, your Electrum will not connect online nor synchronize with any central server.

If you care about privacy the most and you don't want to leak your IP to a 3rd party server, then having a Tor, as suggested, is the easiest one, but you can try without using Tor, but this time you'll need to set up your own server and connect your Electrum, but the problem is you need to download the entire blockchain because most Electrum servers do not support pruning, but I think EPS or Electrs support pruning.
If you have a 1 TB drive or have any device with Umbrel, then you can run your own server.
Having this is far from leaks, and you have full control of your server.
