Quick TakeImmutable X is an NFT layer-2 scaling solution that aims to provide gasless transactions and solve the fragmented liquidity in the current NFT marketplace landscape. To address the liquidity issue, Immutable X has implemented a global order book, where liquidity is shared among the marketplaces on its platform.However, Immutable X has a 2% trading fee, whereas a third-party NFT marketplace would have to add taker or maker fees on top of it. To offer competitive trading fees on Immutable X, third-party marketplaces are likely to engage in a price war or would eventually internalize the take rate themselves.
