On iOS, yes. You can purchase, list, and make offers on Solana NFTs in the OpenSea app.
Update the app if you are on an older version, since Solana actions need the latest release.
In the app, tap the item you want, then tap Buy now or Make offer.
To list an item you own, open it from your profile, tap List for sale, set your price, and tap Complete listing.
Approve the transaction in your Solana wallet.
On Android, you can browse Solana collections and items in the app, but purchasing, listing, and offers are not available there yet. To purchase, list, or make an offer from an Android device, open opensea.io in your mobile browser and connect your Solana wallet there.
Escrow, network fees, and account deposits work in the app exactly as they do on the website. To read about those, see "Why did my Solana NFT leave my wallet?" and "Why do I need SOL to list or buy a Solana NFT?" in the Help Center.
