GameStop launches NFT marketplace on Immutable X GameStop is partnering with Immutable X for the launch of its non-fungible token (NFT) marketplace. The retail gaming staple is taking a carbon-neutral swing at Web 3 with no shortage of bankroll. Both platforms will also be creating an up-to-$100-million fund dedicated to providing grants to game developers and studios to build on Immutable X and the NFT marketplace. GameStop believes that building on the Immutable X protocol will enable faster, more affordable, carbon-neutral, and nearly limitless transactions on GameStop’s NFT marketplace, which is being built for launching gaming developer-focused NFT projects.
