Even though Walrus is built on the Sui blockchain, its design allows it to serve a broader purpose. It can provide decentralized storage for apps on other blockchains too for example Ethereum or Solana via standard APIs and integration layers. This means Walrus has the potential to become a multi-chain data layer, not tied to a single ecosystem.
This matters because storage needs are universal. Whether an app uses Ethereum for computation or Sui for logic, the data itself can live in a common, decentralized storage network that anyone can plug into. That level of interoperability moves storage out of being a bottleneck and into being a shared utility for the entire Web3 space.
