Decentralized storage has long been plagued by ecosystem fragmentation. Filecoin heavily relies on the IPFS ecosystem, while Arweave mainly focuses on its own network. The application scope of these protocols is often limited by the native blockchain, making it difficult to adapt to a multi-chain market landscape.

Walrus has taken a different approach. Although born in the Sui ecosystem, it makes "cross-ecosystem compatibility" its core strategy. Through cross-chain bridging and adaptation layer technology, Walrus already supports mainstream public chains such as Ethereum and Aptos, becoming the industry's first truly multi-chain decentralized storage protocol. Its native token WAL has also evolved into a multi-chain universal storage payment and incentive tool.

This cross-ecosystem compatibility offers advantages in two key aspects:

**Technical adaptation breaks down barriers** — Walrus has developed a universal storage adaptation layer capable of supporting different blockchain smart contract standards. This means that DApps from other ecosystems can access Walrus's storage services without major code modifications. For example, DeFi projects on Ethereum can store risk control data on Walrus, then verify data availability via cross-chain credentials, enjoying low costs and privacy protection.

**Seamless cross-chain asset transfer** — Through partnerships with leading cross-chain bridges, users can exchange stablecoins or tokens from other chains into WAL to pay for storage fees, while storage credentials are cross-chain returned to the original ecosystem. This "payment-storage-credential return" closed-loop operation significantly reduces the usage costs for multi-chain users.

From a token value perspective, WAL's role is also amplified. Regardless of which blockchain users come from, they need to use WAL to pay for storage fees. As cross-ecosystem expansion continues, the demand and usage scenarios for WAL will keep growing, forming a true multi-chain value flow.
