What is Etherum?

“Ethereum is open access to digital money and data-friendly services for everyone – no matter your background or location. It’s a community-built technology behind the cryptocurrency ether (ETH) and thousands of applications you can use today.” – etherum.org


Like any great system, Ethereum technology runs on fuel. This fuel is called Ether (ETH). ETH is also a cryptocurrency that can be used to buy digital art (e.g in the form of NTFs). 


What makes purchasing with ETH better than with a credit card is that all transactions are atomic. This means that when you make a purchase order, the transfer of yours-to-be NFT and your ETH balance are interlinked, happening at the same time. In addition there are no bank fees, waiting times or other legacy problems common to the SWIFT network.

How do I get Ethereum (ETH)?

There are two types of channels to buy ETH. 

  • Exchanges (e.g. Kraken, Binance) – this is where you can also trade with your cryptocurrencies.
  • Wallets (e.g. MetaMask) – this is just for buying and holding your ETH. Depending on the wallet, you can easily buy, hold and withdraw your ETH at any time. Withdrawing ETH is just like sending your FIAT currency to another account, you are just sending ETH.

How does the purchase process look like?

If you wish to acquire ETH we recommend going with wallets. Depending on which wallet you use, your experience will vary, but most of the time it is the following:

  1. Signup: Choose email and secure your account by choosing a strong password and setting up multi-factor authentication if possible.


  2. KYC: Depending on the wallet you will or don’t have to do KYC. You only do this once, and the wallet is with you for the rest of the years to come. In this process you simply upload your ID card or passport photo and a selfie. Wallets usually KYC you within 5 minutes.
  3. Buy: Select and open an Ethereum (ETH) account and click on Buy. You can buy with wire transfer or Credit Card.

The wallet will process your purchase, usually within 10 minutes after which your wallet will show ETH balance. Near your wallet you will also see your wallet address (e.g. 0x29D7d1dd5B3g7C864d9dDqcw6o5GNn7c178aE86B).

Which wallet to use?

Because Peppermint works with the OpenSea marketplace, you need to have ETH on your MetaMask wallet. You can buy ETH directly inside MetaMask wallet, or transfer your ETH from another account into MetaMask. Read how to transfer here. 


MetaMask wallet works both on mobile application (both iOS or Android) and as a browser extension. You need the browser extension to shop on OpenSea and we also recommend getting the app as you can have a better ETH buying experience and can keep an eye on your assets on the go.
