Recently, I noticed an interesting phenomenon—some projects have launched on-chain US stock trading products like STOCK, allowing users to directly trade tokenized assets of top US companies such as Tesla and Apple on the blockchain. Although the market capitalization is still small and there are cases of oversubscription, this direction is quite intriguing.

Even more interesting is that traditional financial institutions are starting to experiment as well. For example, Interactive Brokers, a well-established brokerage, has recently enabled USDC deposits, indicating that Web2 financial giants are also sensing the opportunities in Web3.

However, while delving into tax issues, I discovered a key point—under the domestic CRS framework, there is indeed a 10-year retrospective period. This means that participating in US stock trading within Web3 involves significant tax compliance considerations. Conversely, these compliance complexities actually make Web3-based US stock trading more flexible and advantageous compared to traditional channels—if you understand the rules clearly, many trading scenarios can be handled more effectively.
