Against the backdrop of the volatile US stock market and cryptocurrency assets regaining some attention, @ RobinhoodApp Chian has emerged. Why is it said that its emergence is an absolute big benefit for ETH? Let me share my personal opinion: 1) Robinhood Chain is certainly a representative of TradFi institutions or Wall Street veterans, but this time it did not build its own Layer1 chain like other institutions. Instead, it was built based on the Ethereum Layer2 Arbitrarum Orbit technology stack, which actually shows that the Ethereum mainnet's technical logic of providing Layer1 to Layer2 with security and finality is not outdated. Robinhood's choice is tantamount to verifying the rationality of the Ethereum Rollup Centric route, providing more reference samples for institutions. Future institutions may be more inclined to build application chains based on Ethereum rather than rebuilding wheels, which is crucial for consolidating the anchor position of Ethereum's secure settlement layer; 2) Robinhood itself has a large group of Gen Z young people who are more inclined towards high volatility assets such as cryptocurrency and MEME. The CEO has always embraced MEME, and CASHCAT has indeed become the focus of attention for Robinhood Chain. This is very important. The way TradFi integrates DeFi cannot simply move traditional products onto the chain, but should prioritize native cryptographic gameplay in order to maximize the potential of the on chain economy. It should be noted that once Robinhood Chain has more phenomenon level MEMEs, its radiation population will not be limited to the existing cryptocurrency market, but will bring many incremental traditional retail users into the cryptocurrency ecosystem; 3) The emergence of Robinhood Chain has brought about transaction fees of three to four million US dollars per day for the @ Uniswap protocol, and even the newly launched MEME launch platform NOXA Fun earns around one million US dollars per day in transaction fees. Although these numbers are still far behind the peak DeFi ecosystem, they are a direct reflection of Layer 2's high activity feeding back into the Ethereum ecosystem. Of course, giving back to the ecological protocol may not necessarily have a direct relationship with the holder of the ecological token, but earning money from the protocol can greatly help attract and retain excellent developers; 4) This time, Robinhood Chain, as a compliant and regulated TradFi platform, tells a new narrative by launching real world assets such as tokenized stocks, ETFs, RWAs, which means that in the future, DeFi lending or other derivative markets such as Perps will directly bring liquidity to real assets. This not only enriches the categories of tradable assets on the chain, but also expands the asset volume of the entire crypto world, which can solve the problem of unstable foundations in DeFi composable Lego financial buildings, and explore more financial innovation gameplay in the flexible crypto native market. Although Robinhood Chain is still only playing the MEME attention economy, what is truly worth paying attention to is the market chemistry reaction after its new narrative is gradually implemented.
