I opened both from seed and the connection was made thru Tor.
Well, it depends how you look at it. In basic terms, no - with blockchain, no one can directly connect that both wallets are owned by the same person. But if we're talking the Electrum server then yeah, I'd say there's a way. Cause both wallets likely use the same server, right? And those servers can log IP addresses and stuff and so if both wallets is accessing the same server from the same IP, then the server admin could potentially link transactions from both to the same user.
I dunno its kinda tricky. But servers see IP addresses and traffic patterns and all that. So there's a ways to connect dots if someone digs deep enough. But in simple terms - blockchain, no. Servers maybe yes.
