Someone asked for help with this signature and couldn't understand its meaning, but accidentally signed it out. Now they are very worried about whether there is any risk. This used to be a popular science topic, but this time I am preparing to keep up with the times and let the "smart" AI interpret it. I will use the simplest prompt words like this: What does the following EVM transaction data mean? 0xb510391f0000000000000000000000006f7c3f5d95d283b07717667f1db25f27db84945900000000000000000000000000000000000000000000000000000000000000400000000000000000000000000000000000000000000000000000000000000044449a52f8000000000000000000000000e2711050777777777777777dc1d443bae6773d40000000000000000000000000000000000000000000000000000000000000000100000000000000000000000000000000000000000000000000000000 I use such simple prompts because of the complex questioning methods that players may not easily master. I compared Grok 3 DeepSearch and found it helpful, but the results were average https://(x.com)/i/grok/share/z6of0SXQAMoXygAMqatWh6uMy But at least tell the user that they can go https://www.4byte.directory/ What does the function selector 0xb510391f mean when searching for the first 4 bytes? Actually, you can tell it's mint (address, bytes) just by looking it up, but Grok 3 just doesn't know, and if you ask too many questions, you'll guess randomly Of course, other models such as DeepSeek R1, OpenAI o1, Google Gemini 2.0 Flash Thinking, Grok 3 Thinking, etc. are similar and have not been found to be very useful so far. In summary, if you see an unfamiliar signature like Figure 1, you can directly look at the first 4 bytes of the input data (i.e. 0xb510391f) and use https://www.4byte.directory/ You can easily see the result shown in Figure 2, which indicates that this is a mint operation. As long as you pay attention to whether the amount you send is what you expected and the target contract is not Pixiu, there should be no problem with this operation. If you want to know more details, you can directly use tools related to Input Data Decoder to assist, such as https:// In (etherscan. io)/inputdatadecoder without ABI mode, simply analyze the Input Data and the results are shown in Figure 3. Finally, these are not the main points. The key is, can we avoid using wallets with incomplete basic parsing in the future? Many excellent wallets have long been able to handle such issues well, with secure user interactions and devil's worth of details
