# Guidelines for using the token contract security detection tool

Completing token trading in DEX is a function we often use in our daily life. Because of the decentralized openness of the token trading platform, anyone or team can list different types of tokens. In this process, some lawless elements will tamper with the token contract, such as untradable (pixiu) tokens, tokens with additional issuance functions, etc. At this time, you need to use the token contract security detection tool. Although the tool's detection cannot guarantee 100% accuracy, it can largely eliminate some risks and choose safer tokens for trading.

1\. Open StarTower, click on any token you want to detect, and then click \[Project Details] in the upper right corner of the interface that opens.

2. In the details interface, you can see the contract address and issuance volume of the token. In the lower part, you can see the risk warning content of the token, which is generally divided into \[Danger Warning] and \[Safety Warning]. Danger warning has the highest level. Click \[View more safety information] to jump to the contract detection details, where you can view the safety detection details of the token contract address.
3.  At the beginning of the security detection details interface, there is an embedded small tool. Click the public chain option on the left to select the public chain supported by the tool. Currently supported are: Ethereum, BSC, Polygon, Avalanche, Arbitrum, Heco, OKC, Fantom, Harmony, Cronos, and more public chains are being supported.

   After switching to the public chain, fill in the contract address and click \[Detect] to complete the token contract detection.
4.  Now that you are familiar with the entrance and functions of the token contract viewing tool, let’s briefly introduce some common \[Danger Warnings] and \[Safety Tips] contents.

   Proxy contract: The token contract code is bound to another contract, which can control its issuance, trading switch and other functions, and is highly dangerous.

   Pixiu Token: If you cannot sell the token, then the token will have no value.

   Whitelist function: Only those who join the whitelist can buy and sell tokens.

   Anti-whale function: prevent large amounts of funds from buying and gaining control of tokens.

Blacklist function: Addresses added to the blacklist cannot sell tokens. This setting can be used in conjunction with the robot-killing function.

Additional issuance function: Increase the function of token issuance, for example, some mining projects are used for mining or some malicious projects increase issuance to crash the market.

The launch of the token contract address security detection tool can largely avoid some malicious tokens. The tool only plays an auxiliary role and its accuracy cannot be guaranteed to be 100%. Subsequent functions will be added to the token details of the market interface.
