Why 2 Outputs When Sending Bitcoin?

[rjg20000]

Hello, Need some help with Electrum, I am trying to send 0.179 BTC from Electrum wallet with 2FA to an exchange. However, when i preview the transaction, I am seeing a 2nd address in there with 0.01 BTC. Anyone have any idea why there is a 2nd address in there requesting 0.01 BTC? No idea what the 0.01 BTC or the 2nd address is. Want to make sure wallet is not compromised.

Thanks

When you send a transaction, the input has to equal the output plus the fees. That means you have to send the entire 0.0279. The 125XE6W8SX6vK569jGFCNahMWakqiSb4uG is probably a change address that you own.

You choose to not use change addresses by going to Tool => Electrum Preferences => Transactions and then uncheck change addresses and the extra 0.01 btc will be sent back to your original address.

No... It isn't a change address

You have a 2FA wallet, so you need to pay TrustedCoin for providing the 2FA service. You either prepay and get credits (likely 100 transactions for your 0.01 btc at a rate of 0.0001/transaction) or you can "pay as you go" but at a higher rate of 0.0005/transaction.

Click the little blue shield icon in the bottom right corner of Electrum window for more info...



Note: Be careful what you click on that screen, as it won't clear you selection unless you click the "clear all" button on the send tab. Several users have accidentally bought 100 credits for 0.01 btc in recent months
