- Reminder function for TOKEN or NFT approval signature
When you do the operation with the contract, if you see this reminder in this position, it means that this is an approval signature, and the target address will have the right to transfer the approval asset without any operation from you. So you need to be vigilant and ensure its safety before proceeding.
(This reminder function can only identify some approval signatures, and only serves as a reminder. When performing any operation, you should confirm it again and again to ensure asset security)

In order to further improve security awareness, we can learn about the common methods used by scammers
(General reasons for theft: 1. Private key leakage; 2. Contract approval)
Some Cases
- Case 1: Phishing website steals private key
AA is a new user entering the WEB3 world for the first time. The scammer put up special discounted items on a certain platform and trade with AA. Provide AA with a phishing website, guide him to download a pirated APP, and defraud his private key .Then the scammer transfers AA’s assets away.

- Case 2: Fraud DAPP and Malicious Approve
BB has been in the WEB3 world for a while, and has a certain understanding of the basic functions of the wallet.
Through a certain social platform, BB learned about an unknown DAPP. And heard that it can make money, so he followed the tutorial given by others and interacted with it. One of the signatures was malicious approval . Subsequently, one of the tokens in the wallet account were secretly and totally transferred without any operation by BB.

- Case 3: Malicious approval disguised as a transfer page
CC is trading with someone else, but this person is actually a scammer. The scammer provided CC with a QR code and guided him to scan the QR code to transfer token. The QR code jumps to a website, and the scammer carefully crafted it into a transfer page. As long as CC performs a signature operation, he will be maliciously approval. Subsequently, one of the tokens in the wallet account were secretly and totally transferred without any operation by CC.
(Tip: When using the mathwallet app, scan the QR code on the wallet token transfer page. If the QR code is not a wallet address, but a link, the app will pop up a window to prompt the link address details)
If you have other cases, please provide them to us to remind more people and avoid being deceived
