1. Download Coinbase Wallet
A self-custody wallet like Coinbase Wallet is required to purchase Chromia. Coinbase Wallet is available as a mobile app and browser extension. Download Coinbase Wallet here.
2. Choose a Coinbase Wallet username
As part of setting up your Coinbase Wallet, you will need to choose a username. This username lets other Coinbase Wallet users easily send you crypto. You can keep your username private, but you will need one to access the account.
3. Securely store your recovery phrase
When you create a new self-custody wallet, you'll be given a recovery phrase that consists of 12 random words. The recovery phrase is the key to your crypto, meaning anyone with your recovery phrase has access to your crypto. Do not share your recovery phrase with anyone.
We strongly recommend writing these down on paper and storing them securely, as well as using Coinbase Wallet's cloud backup feature.
Remember, do not share your recovery phrase with anyone. Coinbase will never ask you for your recovery phrase. And if you lose your recovery phrase, Coinbase cannot help you access your wallet.
4. Understand and plan for Ethereum network fees
Fees vary based on how busy the network is, how complicated the transaction is, and how fast you’d like the transaction completed. Plan to set aside some money for fees. Learn more about Ethereum fees here.
