Buy, sell, and mint NFTs at OpenSea now

Here’s the fast, easy way to establish an account and participate in the bustling OpenSea NFT marketplace.

1. Set up a MetaMask wallet

MetaMask is a crypto wallet that is implemented as a browser extension on PCs and an app on mobile devices. Visit Metamask.io and select “Download” and you will receive the proper version for the device you are using. Follow the instructions to complete the installation. Create a wallet and password. Set up the wallet to use the Ethereum mainnet. 

Now you can use the MetaMask Account Details menu to display the numeric code that is your MetaMask wallet address for the Ethereum mainnet.

2. Purchase Ethereum and transfer it to your MetaMask wallet

Your OpenSea journey requires that you have some Ethereum. Simply use the tool at the top of this page to specify how much Ethereum you wish to purchase and where it should be sent – to the MetaMask wallet address you acquired in Step 1. Visa and Mastercard support mean you can complete this process in minutes. (If you have a Kriptomat account, you can acquire and send Ethereum in the normal way.)

3. Connect your MetaMask wallet to OpenSea

Navigate to OpenSea, click on the profile icon, and follow the instructions on your screen to link your MetaMask wallet to your OpenSea account.

4. Begin trading

Now that you have funded your MetaMask wallet, you are ready to begin buying, selling, and creating NFTs at OpenSea. The OpenSea website maintains detailed, updated instructions for these tasks:
