# Whitelist Rules Description
The DeSyn platform offers two types of whitelist mechanisms that guarantee compliance and pool security.
### **1) Investor whitelist**
* The pool owner can determine which investors are allowed to invest in a specific pool. This feature supports various compliance operations within the financial sector.
* A pool owner can enable an “Investor whitelist” option in \[Advanced Settings] when creating a pool, as shown below.
* After enabling the Investor Whitelist while creating the pool, you need to add the investors in \[Pool Detail Page → Settings→Investor Whitelist], otherwise the portfolio can’t be traded.
### **2) Token Whitelist**
* The “Investment Token Whitelist,” is mainly used to determine the investment scope of the pool. This function mainly controls the risk of the pool by limiting the investment tokens that can be invested.
* The Investment Token Whitelist on the DeSyn platform implements a two-level whitelist mechanism, the DeSyn community will form a wide-area list of investment tokens based on the various data of these tokens in each market, which we call the first-level whitelist, and the DeSyn community owns the right to adjust this first-level whitelist.
* Pool owners can build their own pool Token whitelist to restrict investment tokens. We call this whitelist a secondary whitelist.
* The secondary whitelist can only be set once at the time of issuance, once set, it cannot be modified. If the pool owner doesn’t enable token whitelist, the scope of the first-level whitelist will be used as the limit by default.
* Pool owners can enable the “Token Whitelist” option in \[Advanced Settings] when creating a pool, as follows:
* After enabling the Token Whitelist while creating the pool, you need to add the Tokens in \[Pool Detail Page → Settings→Investment Token Whitelist], otherwise, the pool can’t be traded.
