Additionally, developers can leverage the same SDK to construct their own NFT rental marketplaces. Web3 gaming revolutionizes the user experience within games. Nevertheless, the majority of gamers find NFTs unaffordable, as they are accustomed to the free-to-play model. Gamers desire the opportunity to fully experience games before committing their resources. Stash addresses this challenge by introducing rentals for NFTs. By enabling NFTs to be rented, users gain the ability to test and utilize gaming NFTs for a specific duration of time.
