Video game retailer GameStop announced Monday the launch of a public beta version of a non-fungible token (NFT) marketplace amid the downturn of the crypto-market.  The company's NFT marketplace-is a non-custodial, Ethereum-based layer 2 marketplace that enables parties to truly own their digital assets, which are represented and secured on the blockchain.  Users are allowed to connect to their own digital asset wallets such as the recently launched GameStop wallet, according to the statement.    The new feature product just comes amid the downturn of the crypto market.  Currently, there are 236 NFT collections on the public beta NFT marketplace, and more than 53,000 NFT's listed on the marketplace.    Clients can use this Ethereum layer 2-based non-custodial application to buy, sell and trade NFT's related to digital assets used in various games.    Partnering with Loopring, an Ethereum compatible zkRollup protocol will provide players with faster, cheaper, and more secure access to digital property rights.  As Loopring zkRollup is based on Ethereum's self-hosting security while extracting expensive gass fees, it reduces customer costs.
