# CRC\_Contract

The CRC\_Contract class is defined in the Contract.hc file, where ‘hc’ stands for Hyper Code, Circular Protocol’s smart contract architecture. Hyper Code is a simplified variant of JavaScript designed specifically for smart contract development on Circular. The class is structured to manage contract logic and interactions efficiently within this streamlined language. Here’s a brief look at how it works:

```javascript
var CRC_Contract = {
                      property1 : "string", // string
                      property2 : 1.0,      // number
                      
                      method1: function(parameter1, parameter2){
                      
                      /*do something*/
                      
                      return true;
                      },
                      
                      method2: function(parameter1, parameter2){
                      
                      /*do something*/
                      
                      return true;
                      }
                    };
                
```
