You can connect Phantom to OpenSea to browse, buy, sell, and manage NFTs on supported chains. During connection, OpenSea may ask you to select a chain and sign a message to confirm wallet ownership.
Warning: Only connect your wallet to trusted marketplaces and websites. If a site asks you to approve an unexpected transaction, check the URL and review the request carefully before continuing.
