How do I check the balance of my Electrum wallet on Blockchain.info? When I use the main public key I use for all incoming transactions it doesn't give me the correct balance when I enter it into Blockchain.info. Electrum gives you multiple key options for importing money I only use 1 of them. That one key when entered into block chain it shows me the wrong balance, why is that?
Electrum combines all the balances for all addresses it generates from the master public key up to {gap limit} unfunded addresses.
If you want to get the same balance reported in blockchain you'd need to manually import all the relevant private keys there, which is by the way strongly advised against as it may leak information about the private seed.
TL;DR: What you're trying to do doesn't make much sense since blockchain and electrum work in very different ways, and it might even be dangerous.
