Doudian transaction grade refers to the transaction performance rating of sellers on the Douyin e-commerce platform. Doudian refers to a store opened on the Douyin platform where sellers can sell goods. In order to evaluate the seller's transaction performance and credibility, the Douyin platform will give the seller a transaction grade based on factors such as the seller's sales data and buyer evaluation.

Transaction grades are usually divided into several levels, such as silver, gold, and diamond levels. Different levels represent the seller's transaction ability and credibility. The transaction grade is a trust certification of the Douyin platform for sellers. For buyers, it is also a reference for choosing to buy goods. A higher transaction grade usually means that the seller's product quality and service level are higher, and buyers can buy with more confidence.
