Preparation before operation must be done properly—network connection, GAS fee budget, and basic token concepts should all be clear. The transfer logic of WEB3 wallets, the characteristics of MEME coins, and CA address queries should also be understood. Speaking of which, the risks in the primary market have always been high, so it's important to think about an exit strategy before entering.

This article will walk through the complete process using a real example on the BSC chain. Assuming your wallet already has funds, let's get started.

**Buying Section**

Step 1: Open the wallet page and locate the search bar. Enter the CA address of the token you want to trade; the system will automatically recognize the token information.

Next, click on the quick buy/sell option. Here, you can choose BNB, USDT, or other on-chain assets as payment methods, and input the desired purchase amount. After confirming the amount is correct, submit the order. The wallet will pop up a security verification window—just follow the process to complete it. In a few seconds, the tokens will arrive.

After a successful purchase, go directly to the assets page and refresh; the newly bought tokens will be there.

**Selling Section**

There are two ways to sell. One is to jump directly from the assets page to the exchange page, select the token to sell, and input the sell ratio or amount. A crucial detail not to forget—enable MEV protection. After turning on protection, click confirm, and the sell order will be submitted.

The other way is to search for the CA directly on the quick exchange page, similar to the buy logic. Enter the sell amount, click sell, and complete the verification process.

After selling, you can also check the entire process in the assets page or transaction records.
