Hi sure, etherscan shows detailed transaction of a particular address, whereas FindETH scans through your hardware (or addresses) for all addresses created using your private key (obviously your key doesn't leave your hardware you just sign it) and it will scan through addresses possible under different derivation path.

For me it's useful as I have ETH where the addresses is created using different provider (derivation path) such as MEW, Ledger Live and sometimes I worry where did I put my ETH....

And thanks for reminding me to move the thread to Altcoin!

merry christmas~
