#跨链基础设施与互操作 Cross-chain payment layer actions are happening frequently. The modular SDK solution of x402 V2 reduces development access costs, and the wallet-based payment mechanism addresses the pain point of repeated authorization. This approach is worth paying attention to. But what truly matters to track is the flow of funds—Coinbase has chosen Chainlink CCIP as the exclusive infrastructure for $7 billion Wrapped Assets. This is not only a technical choice but also a trust vote from major institutions on cross-chain solutions.

An even more critical signal comes from JPMorgan piloting $50 million in commercial paper settlement on Solana. The bank's entry into bond tokenization, choosing Solana over Ethereum, indicates that institutions are evaluating the settlement efficiency and costs of different chains. Testing in these real fund scenarios will create ongoing demand for on-chain infrastructure.

Recent progress in cross-chain interoperability integration is accelerating, but whether it can become mainstream depends on actual transaction volume and institutional participation. Key metrics to observe are the daily average transaction volume and TVL changes of these protocols.
