Imagine your crypto assets are spread across multiple chains like Ethereum, Solana, Avalanche, and more, requiring flexible movement between them. It sounds great, but the reality is much more complicated.

Every time you perform a cross-chain transfer, there's a bit of anxiety—are my assets really safe? Are those cross-chain bridges truly reliable? This is not just paranoia; these are real issues in the multi-chain ecosystem. Simply put, trust is something that hasn't yet truly crossed the boundaries between different blockchains.

**The Trust Gap Between Chains**

Each blockchain is an independent system with its own validation rules and consensus mechanisms. This is not inherently problematic, but issues arise when assets need to move. Verifying a transaction on Ethereum is straightforward, but that trust credential becomes invalid on Solana or Arbitrum. What are the consequences of this disconnect? Very real—cross-chain operations carry significant risks.

When assets cross a bridge to another chain, the target chain cannot verify the true origin of those assets natively. In complex scenarios, the risks are further amplified. Not to mention the numerous attacks on cross-chain bridges, where millions of dollars can vanish in the gaps between chains.

**The Current Multi-Chain Landscape**

We are now in an unprecedented multi-chain era. Ethereum remains the main hub for finance, Solana is known for its high speed, Avalanche and Polygon each have their unique features. On the surface, this multi-chain proliferation seems beneficial. But the reality behind it is that these chains are essentially isolated trust islands.

You can verify transaction finality seamlessly on Ethereum, but that certainty cannot be directly transferred to other chains. As a result, cross-chain operations become high-risk, low-efficiency processes. Asset states are difficult to trust natively across chains, which significantly hampers the liquidity of the entire ecosystem.

**Why Is This a Core Issue?**

As more Layer 2 solutions and new public chains emerge, this problem will become even more prominent. The development of the DeFi ecosystem requires assets to move freely, but under current cross-chain mechanisms, this flow always involves a trust discount. Frankly, the multi-chain universe needs not more bridges, but truly innovative solutions that can bridge the trust gap between chains.

This is a difficult challenge facing the entire industry and also a breakthrough point for future innovation.
