This article walks you through the process of connecting your Phantom wallet to the OpenSea NFT marketplace. You can connect your Phantom wallet to OpenSea to browse, buy, sell, and manage NFTs across multiple chains.
Warning: Only connect your wallet to trusted marketplaces. If a site asks you to approve unexpected transactions, always double-check the URL and be cautious.
