I'm looking for a wallet which can scan many ethereum addresses balance,(like electrum for bitcoin). I need to import 200 (or more) eth addresses and scan their balances include their tokens(if funded). I've already used electrum for bitcoin and now I want something like that for ethereum. It's appreciated if someone guide me? I'm even ready to pay someone who can write a code for this reason. A customised ethereum wallet just for scan the balances, not for send & receive ethereum.
