What is Alipay secured transactions?

I grabbed a Xiaomi mobile phone reservation number on the Internet, but I didn't want it. I felt that it was more cost-effective to buy Xiaomi mobile phone 2, so I sold the reservation number, and the other party asked me to make a link payment on Taobao. However, I did not open a store in Taobao. The other party said that it is safe to use Alipay to secure the transaction.

I want to ask everyone, who knows Alipay secured transactions, is it safe?

A: The Alipay secured transaction is similar to the way Taobao buys goods. If the other party pays you money through the Alipay secured transaction, the money will not be transferred to your Alipay immediately, but will require the other party to confirm. You can become your own money. If the other party does not apply for a refund within the specified time, and the confirmation is not made, the money will be safely hit on your card.
