We will download MetaMask, set up an account, and copy your private key for use in the next lessons. We'll also briefly learn about the structure of a browser-based non-custodial wallet.

Non-custodial wallets are wallets where no other party holds any private information about it. This makes it very powerful — in that you have 100% control over what goes on in your wallet. But it also means you are ENTIRELY responsible. There is no do-over button, no password reset, and no support agent to help you out should you go down the wrong path.
