Uniswap, as a highly-watched decentralized trading platform in the cryptocurrency world, recently announced that it will support U.S. stock trading, which has attracted widespread attention. However, the mapping problem that follows cannot be ignored. In this article, we will explore the possibility of Uniswap opening U.S. stock trading, as well as the challenges and impacts that the mapping problem may bring.

Uniswap, as one of the most popular decentralized trading platforms on Ethereum, has been committed to providing a safe and efficient trading experience. Recent rumors show that Uniswap is expected to support U.S. stock trading, and this news has caused quite a stir in the cryptocurrency community. If Uniswap really supports U.S. stocks, what impact will it have on the traditional financial market? And how will the mapping problem involved affect the stability and security of transactions? Next, let's explore it in depth.

As a model of decentralized trading platforms, Uniswap's plan to support U.S. stock trading is undoubtedly a bold and forward-looking move. The bridge between the traditional financial market and the cryptocurrency market is gradually being established, and this move by Uniswap will further promote this trend. By trading U.S. stocks on Uniswap, investors will be able to participate in the global financial market more conveniently, realize asset diversification, thereby reducing investment risks and improving returns. This move will also inject new vitality into the cryptocurrency market, attract more traditional investors to enter this field, and promote the development and growth of the market.

However, although Uniswap's plan to support U.S. stock trading is attractive, the mapping problem cannot be ignored. The mapping problem refers to the mismatch and risk that may arise when mapping assets between different financial markets. After Uniswap opens U.S. stock trading, how to achieve a good mapping between U.S. stocks and cryptocurrencies and ensure the liquidity and value stability of assets will be a very challenging problem. Historically, similar mapping problems have occurred on other trading platforms, causing considerable losses and risks to investors and exchanges. Therefore, Uniswap must be extremely cautious when dealing with mapping problems and take effective risk control measures to ensure the security and stability of transactions.

To solve the mapping problems that may be caused by Uniswap opening U.S. stock trading, it is necessary to comprehensively consider and respond from multiple aspects. First, Uniswap needs to establish a sound asset mapping mechanism to ensure unimpeded exchange and liquidity between US stocks and cryptocurrencies. Secondly, Uniswap needs to strengthen the monitoring and analysis of transaction data and asset values, and promptly discover and respond to potential risks and problems. In addition, Uniswap can also learn from the experience and lessons of other trading platforms, learn from their successful practices and lessons from failure, and continuously optimize and improve its own mapping mechanism and risk control measures.

In summary, although Uniswap's plan to open US stock trading is full of appeal and potential, the mapping problem is a challenge that cannot be ignored. Only by treating the mapping problem with caution and establishing an effective risk control mechanism can Uniswap achieve long-term stability and sustainable development of US stock trading. In the future, as Uniswap's support for US stock trading gradually advances, I believe that Uniswap will become a dazzling star in the financial market, bringing more opportunities and choices to investors.

On December 4, the synthetic asset protocol Mirror
Protocol launched by the stablecoin project Terra was officially launched. The protocol can track the prices of stocks, futures, exchange-traded funds and other traditional financial assets, thereby integrating the cryptocurrency market with the traditional market.

At present, stock tokens such as Apple, Tesla, Twitter, and Microsoft have been minted on Uniswap for users to buy and sell freely. Simply put, Mirror uses synthetic assets mAssets
to solve the problem of "US stock minting". The principle is to "mirror" the price of real-world assets by reflecting the transaction price on the chain, and traders can trade the price of real assets.

Today, investors can exchange USDT stablecoins for Terra stablecoins (UST), and then provide liquidity on Uniswap, mortgage
LP, and obtain MIR token rewards. MIR is a governance token issued by Terra, with a total issuance of
370,575,000. Overall, since the price fluctuations of US stock assets are relatively small, the risk of users providing liquidity for US stock tokens is relatively small.

On the surface, Terra seems to provide a channel for global users to freely trade US stock assets without any KYC certification. However, the study society reminds that users holding "US stock tokens" does not mean that they actually own the stock in reality. It is just anchoring the price of the asset, and there will be no so-called dividends. In order to keep the token price consistent with the US stock price, mAssets uses the oracle mechanism (bandprotocol) to track and update the price every six seconds.

It is worth noting that the oracle cannot completely guarantee that the price of "US stock tokens" is consistent with the anchored US stock price. In addition, although US stocks are a very attractive asset class in the world, Terra has not yet made any explanation on the mapping problem between US stock tokens and US stock assets questioned by the market. Users should understand the market risks behind it before trading.
