Can someone recognize any two addresses (generated by hardware wallet) come from the same hardware wallet/mnemonic seed? Can someone recognize any two addresses (generated by hardware wallet) come from the same hardware wallet/mnemonic seed?If I generate multiple cryptocurrency accounts/addresses in ledger live,is it possible for someone to recognize it comes from the same hardware wallet/seed? I would also want to ask the same question for software wallet. Thanks.
Although there is no link between your addresses alone (someone would need your seed, xprv, or xpub for that) you do leave some residual identity once you start spending.
For example if your wallet builds a transaction where two or more of your previously unassociated addresses are used as inputs in the same transaction, then it may suggest that the spender owns both (or more) of those addresses.
Wallet technologies exist that attempt to muddy the waters of those trying to surveil by combining multiple unrelated coin owners to sign a single transaction together with multiple inputs. Basically disproving the assumption that multiple addresses as inputs in the same transactions means one owner owns all the inputs.
