The first restriction is for the apps that offer wallets. Wallets are applications where users can store their cryptocurrencies that they purchase or acquire elsewhere. The name is pretty self-explanatory. Such apps mostly do not offer the functionality to purchase coins and are limited to P2P transfers. From now on only developers that are “enrolled as organizations” will be able to offer such applications. This move reduces the risk of developers placing scammy wallets on the App Store that might compromise the rights of the owners.
Another restriction is placed on the exchange apps. These apps allow users to trade coins for coins and in some cases for fiat money as well. Regulations on such activities are a lot tougher in general as they are usually dealing with users’ money and might have a credit card and other personal information stored on their databases. From now on, only exchanges themselves will be able to place applications on the App Store. No third-parties with only the integration of the exchanges may offer this functionality. “Exchange Apps may facilitate transactions or transmissions of cryptocurrency on an approved exchange, provided they are offered by the exchange itself”. This might be important for the wallets that had integration with exchanges and offered their users simple exchange functionality as well.
