An xNFT (executable NFT) is a new token standard on the Solana blockchain. It is tokenized code representing ownership rights over its execution. This means that developers can create apps that a user can add directly to their wallet. In essence, xNFTs are applications like on a mobile phone. These applications can be built directly into the digital assets that they represent, meaning holders can use the asset however they like within an application itself, without connecting to an external platform.
