<p>While <a href="https://www.theblockcrypto.com/data/nft-non-fungible-tokens/marketplaces/nft-marketplace-monthly-volume">the majority</a> of NFT trading volume happens on the OpenSea marketplace, crypto exchanges are starting to realise they can directly offer a similar service to their millions of users.</p> <p>FTX is one such exchange, with a rudimental marketplace that is getting ready to open up more broadly. FTX CEO Sam Bankman-Fried tweeted today that its latest evolution is to offer the ability to mint NFTs directly on the exchange.</p> <p>This means that FTX users can create their own artworks and mint them as NFTs on the exchange, to be sold within its marketplace. This includes U.S. users, via FTX.US.</p> <p>Bankman-Fried <a href="https://twitter.com/SBF_FTX/status/1434749846880231425">noted</a> that all the NFTs will be cross-chain, across the Ethereum and Solana blockchains.</p> <p>Currently you can only store and view these NFTs within the exchange. But FTX's marketplace will be expanding to support deposits and withdrawals within a few weeks. This will allow users to sell mainstream NFT projects on the exchange.</p> <p>Buying and selling NFTs doesn't come cheap though. FTX <a href="https://help.ftx.com/hc/en-us/articles/360061609792-NFT-Overview">charges</a> 5% to the buyer and to the seller per sale — a 10% fee in total.</p> <p>Crypto exchanges <a href="https://www.theblockcrypto.com/linked/107415/binance-picks-100-artists-to-spearhead-launch-of-nft-marketplace">Binance</a> and OKEx also offer NFT marketplaces. While OKEx <a href="https://www.theblockcrypto.com/post/116428/crypto-exchange-okex-launches-nft-marketplace">only lets you</a> import OKExChain-based NFTs for now, it plans to add support for Ethereum soon.</p>
