PayPal has moved its stablecoin PYUSD to @ Arbitrum. This means that in the future, PayPal related online payment will be faster, lower fees, and easier for businesses and developers to access. Immediately afterwards, Robinhood made a big move: launching tokenized US stocks and ETFs on Arbitrarum technology. Simply put, stocks are traded directly on the chain 24 hours a day, and are also connected to the European market, which is a huge opening for on chain assets. In terms of security, Arbitrarum has introduced the BoLD protocol, which allows anyone to participate in verifying the network, making it more decentralized and stable. At the same time, an ARB equivalent to $14 million was also provided as a "security audit subsidy" to help the project save a significant amount of compliance costs. In order to make the new project easier to start, there is also an ArbiFuel plan that reimburses the early team for gas fees between May and August, which means almost no money is spent on going live. In addition, with the recent development of cross chain account functionality and developer activities, the popularity and foundation of this chain are on the rise. Simply put, with PayPal, Robinhood, security upgrades (BoLD+audit subsidies), and reduced on chain costs (ArbiFuel) - these four legs working together, Arbitrum is truly strengthening its foundation.
