# Asset

The Asset in the DMEX smart contract is a fundamental object that defines the asset being traded in the futures contract. \
\
The Asset comprises of the following information:

| Parameter | Type    | Value                                                                                                           |
| --------- | ------- | --------------------------------------------------------------------------------------------------------------- |
| baseToken | address | the token used for margin (0x000... in the ETH case)                                                            |
| priceUrl  | string  | the url where the Oracle will take the settlement price from                                                    |
| pricePath | string  | the JSON parameter inside the priceUrl that represent the last traded price                                     |
| disabled  | bool    | if true, the asset cannot be used in contract creation (when priceUrl no longer valid or decimals have changed) |
| decimals  | uint256 | number of decimals in the price                                                                                 |

Every Asset has a unique hash. That unique hash is used in the “Asset” parameter when creating a new Futures Contract. There can be no two assets with different parameters but the same hash because all parameters are part of the hash, therefore a change in parameters would result in a new unique asset hash.

```javascript
bytes32 futuresAssetHash = keccak256(
    this, 
    baseToken, 
    priceUrl, 
    pricePath, 
    decimals
);
```
