Interoperability is the key for the metaverse to move from concept to reality, and XAI is setting the standards in this field. Current blockchain games are fragmented; a sword in Game A cannot be used in Game B. XAI's vision is to build a unified underlying protocol that allows assets to flow seamlessly between different games. Imagine earning coins in a shooting game and directly using them to upgrade vehicles in a racing game, with all transactions automatically settled on the chain. When assets can move across application boundaries, the entire ecosystem's GDP will be multiplied tenfold. XAI is laying the "Silk Road" that connects virtual worlds.
