# Default Crypto Assets

Using only the key we can access the default assets for most of the functions within the udrox wallet api

Depending on the selected network you are working with, you can use some keys to make it easier to work with the udrox wallet

<table data-full-width="true"><thead><tr><th width="183.5">Key</th><th>Networks Keys that can be used the asset</th></tr></thead><tbody><tr><td>UDROX</td><td>UDROX, MINTME, MATIC, CRO, BNB</td></tr><tr><td>MINTME</td><td>UDROX, MINTME, CRO, BNB, ETH</td></tr><tr><td>COPC</td><td>UDROX, MINTME, MATIC, CRO</td></tr><tr><td>USDU</td><td>UDROX, MINTME, MATIC, CRO</td></tr><tr><td>USDC</td><td>UDROX, MINTME, MATIC, CRO, BNB, ETH</td></tr><tr><td>USDT</td><td>UDROX, MINTME, MATIC, CRO, BNB, ETH</td></tr><tr><td>WBTC</td><td>UDROX, MINTME, MATIC, CRO</td></tr><tr><td>ETH</td><td>UDROX, MINTME, ETH</td></tr><tr><td>BNB</td><td>UDROX, MINTME, MATIC, CRO</td></tr><tr><td>CRO</td><td>UDROX, MINTME</td></tr><tr><td>WETH</td><td>MATIC, CRO</td></tr><tr><td>MATIC</td><td>MATIC, BNB, ETH</td></tr></tbody></table>

We can see an example of the use

{% code overflow="wrap" %}

```javascript
function transaction(){
    if(walletudrox.net=="UDROX"){    walletudrox.transaction("0x0B77E2947375318fb0F6395A0C36855628685D0a","5","UDROX");
    }
}
```

{% endcode %}

It is also possible to make a transaction only with the contract address of the token that you want to transfer. For example, I am going to transfer 5 personalized Tokens (0xdC33B264de35cF207c661FE37Cb16447F09b74B4) from the MINTME network:

{% code overflow="wrap" %}

```javascript
function transaction(){
    if(walletudrox.net=="MINTME"){    walletudrox.transaction("0x0B77E2947375318fb0F6395A0C36855628685D0a","5","0xdC33B264de35cF207c661FE37Cb16447F09b74B4");
    }
}
```

{% endcode %}

{% hint style="info" %}
At the moment we are increasing the default assets constantly, if you do not find your asset in this list you can use a custom asset in the documentation you can see how to implement it in the udrox wallet api
{% endhint %}
