With the development of blockchain technology, the distribution of tokenized assets (RWA) on different public chains has become increasingly widespread. However, this decentralization has also brought new challenges. Imagine an investor holding tokenized real estate on Ethereum while owning tokenized stocks on Solana. When he wishes to combine these two assets for staking and lending, he finds that the process is not straightforward.

Cross-chain operations have become a tricky issue. Not only do they require paying high Gas fees (around $20), but they also involve long waiting times (up to 2 hours), and there is the risk of asset loss due to operational errors. This situation is akin to having building blocks scattered across different rooms, unable to be effectively combined.

Currently, RWA assets are distributed across multiple public chains such as Ethereum, Solana, and Avalanche, forming independent ecosystems. This decentralization severely hinders the flexible use of assets and the maximization of value.

The main obstacles to cross-chain interoperability can be summarized as "inaccessible, expensive, and slow."

First, there is the issue of technical compatibility. Different public blockchains use different smart contract standards, such as Ethereum's ERC-20/ERC-721 and Solana's SPL. This difference makes it necessary to perform complex 'asset mapping' when assets are cross-chain, and existing cross-chain bridges either only support cryptocurrencies or easily encounter errors such as quantity mismatches when handling RWA.

Secondly, there is the issue of compliance. KYC verification completed by users on one public chain may not be recognized on another public chain. More seriously, an asset that is fully compliant on the original chain may become a "non-compliant asset" after crossing chains due to different regulatory requirements of the target chain. This uncertainty greatly reduces users' willingness to cross chains.

Finally, there is the issue of user experience. Cross-chain operations require users to remember multiple addresses of public chains, use different wallets, and execute multiple complex steps. For ordinary users, this process is both cumbersome and prone to errors. In addition, the "impermanent loss" that may occur during cross-chain transactions is also one of the risks that users need to face.

In the face of these challenges, the industry is actively seeking solutions. Developing a platform that can integrate RWA assets scattered across various public chains, much like putting scattered building blocks into a big box, will be an important direction for the future development of RWA. This can not only improve the liquidity and utilization efficiency of assets but also provide users with a more convenient and secure asset management experience.

With the continuous advancement of technology and ongoing innovation in the industry, we have reason to believe that the cross-chain interoperability issues of RWA will eventually be effectively resolved, bringing more possibilities to the blockchain world.
