According to CoinMeta, the Arc chain of Circle will officially launch on September 16th, and it is expected to bring new enthusiasm to the currently quiet blockchain market. With the success of the Robinhood chain, the launch of the Arc chain could create a wave of DEFI summer market activity. Multiple trading platforms such as Uniswap, AAVE, and Edgex will also launch simultaneously. Edgex plans to introduce its first 24/7 foreign exchange perpetual contract on the mainnet on the first day of launch, covering over 150 perpetual contract markets for cryptocurrencies, U.S. stocks, and commodities. If the Arc chain can achieve the same level of popularity as the Robinhood chain, it will have a positive impact on the projects that launched earlier.
