Once you have the Rainbow app installed on your device, iOS/Android, open it up and tap the "Get a new wallet" button to begin. You now have your first Ethereum wallet, but you need to back it up so you don't lose it.

Step 1: Tap "Get a new wallet" to begin

Step 2: Choose your backup method. In this example, we’re on an iOS device

We at Rainbow don't have access to your wallet, and we can't control it. Your wallet is 100% yours, and the keys to it have been generated cryptographically on your device for your eyes only. It is created using an open standard that is portable and used across the Web3 ecosystem. If you decided Rainbow wasn't for you, then you could easily leave and take your wallet to another app. 🤝
