Does Netease Treasure Hall have a patent?

Netease treasure chest system has a patent. Netease developed it by itself, and obviously won't smash its own brand. The specific operation is that you log in with your account. After you buy something, the system will send it directly to your number. You buy an account and the seller sells an ID. After your transaction is successful, this ID is yours, and it is directly bound to your account. The account password is still the original information of the number you logged in to buy.
