Frequently asked questions

What is Ethereum?

Like bitcoin, ether is a digital bearer asset (similar to a security, like a bond, issued in physical form). Just like cash, it doesn't require a third party to process or approve a transaction.

What is Gas?

Ethereum is the network—the blockchain. Ether (ETH) is the fuel for that network. When you send tokens, interact with a contract, send ETH, or do anything else on the blockchain, you must pay for that computation. That payment is calculated in Gas and gas is paid in ETH.

You are paying for the computation, regardless of whether your transaction succeeds or fails. Even if it fails, the miners must validate and execute your transaction (compute) and therefore you must pay for that computation just like you would pay for a successful transaction.

You can see your TX fee (gas limit * gas price) in ETH & USD when you search for your transaction on https://coinkeeper.io/wallet/transactions. This is not a TX fee that Coinkeeper, or any other service provider, receives. This fee is paid to miners for mining transactions, putting them into blocks, and securing the blockchain.

What is Coinkeeper?

Coinkeeper provides a reliable package of services for ensuring the safety of your wallet and coins, which includes data encryption, as well as two-factor authentication.

What is a mnemocode or a backup phrase?

A backup phrase (or mnemocode) is required to restore your Coinkeeper wallet in case you lose your credentials. You can set up a phrase in the "Security" menu. Write the code down in hard copy and do not pass the phrase to third parties in any case.

How to configure two-factor authentication?

In your account, click the menu option "Security." Install the Google Authenticator app on your smartphone, and scan the QR code with the app. Enter the code into the field and press "Confirm."
