You'll need digital currency, a crypto wallet, and an OpenSea account to start buying or selling NFTs using OpenSea. Let's get started!
1. Digital Currency (ETH)
You can get ETH, the digital currency that fuels transactions on the Ethereum blockchain, from a digital currency exchange like Coinbase. You will need ETH to "mint" an NFT, purchase an NFT, and for gas fees to complete transactions. Gas fees are a bit of a tricky concept, but we simplify the basics in our What are gas fees on Ethereum? help center guide.
Now that you have ETH, let's get a crypto wallet.
2. Crypto Wallet
A crypto wallet, such as MetaMask, stores your ETH and processes transactions on the Ethereum blockchain. A unique wallet address will be generated for you, and you'll use this address to complete transactions.
Watch our tutorial to learn how to install a crypto wallet to connect with OpenSea.
All transactions connected to your wallet address can be found on etherscan.io, an independent blockchain explorer. It's a good idea to check Etherscan after completing each transaction.
Why do I need a wallet before buying and selling on OpenSea?
OpenSea is a tool you use to interact with the blockchain. We never take possession of your items or store your NFTs. Instead, we provide a system for peer-to-peer exchanges. Since you’ll be using OpenSea to interact directly with others on the blockchain, you’ll need a wallet to help you turn your actions in the browser into transactions on the blockchain. You can see the available wallets in our help center guide, What crypto wallets can I use with OpenSea?
Now that you have a crypto wallet installed, you can connect your wallet address to OpenSea.
3. Connecting to OpenSea
Let's connect your wallet to OpenSea and edit your profile so you're ready to begin interacting on our platform. Navigate to opensea.io, head to the top-right profile icon, and select Profile.
You will then be prompted to connect your wallet. You will continue through multiple prompts, finishing with the connection screen. When you see "Connecting..." OpenSea to your wallet, you're almost done.
If you'd like to change your username, select the gear icon on the right side of the screen. You will receive an extra security prompt, select "Sign" and you can begin updating your profile.
Now you can customize your bio, email address, profile photo, and more.
If you ever have trouble viewing your items, make sure your wallet is connected correctly. OpenSea is a window into your wallet address, showing all the NFTs inside.
The heart of OpenSea is the Browse page and search features. Enjoy buying, trading, creating, and selling NFTs on OpenSea!
