1. Setup your wallet

Why do you need a wallet?

What wallet should I get?

  • Metamask: Compatible with most Ethereum-compatible blockchain applications. Recommended for both beginners and advanced users.
  • Rainbow Wallet: UI/UX is really well done here and it’s a great starting point for first-time users. They have a good resource page on their site to educate newcomers to the space. Unfortunately, the app is only available for iOS at this time.
  • Coinbase Wallet: Created by Coinbase. Easier to link with Coinbase.

How can I install Metamask?

  1. Go to the Metamask download page and install

What is a Seed Recovery Phrase?

I am showing you here just to give you an idea of what it a seed recovery phrase looks like — but again, please do not share this with anyone.
  • Never, ever share your Seed Recovery Phrase or private key with anyone.
  • Store your Seed Recovery Phrase in a secure place where only you can access it (ideally, write it down on a piece of paper and store it in a physical location, not on your computer) and never lose it.

2. Get some ETH

How can I set up a Coinbase account?

  1. Create an account: Go to Coinbase and sign up for an account.
  2. Verify your account: You will need to submit your personal information along with a government-issued ID to prove your identity.
  3. Connect your bank with Coinbase: Use Plaid to log in to your bank account and connect your bank account.
  4. (Optional) Set 2FA authentication: In order to make your account more secure (so that even if your username/password get stolen, no one can log in to your account without access to your 2FA code), I highly recommend you set up 2FA authentication. Go to Setting > Security > 2 step verification and choose Google Authenticator, and follow the instructions there.
