# Interface Filters

On the header of the interface are located three filters that can help narrowing the green crypto-asset research. They appear as follow:

The interface filters enable to search according to:

* **Type**, which refers to the overarching categorization that a green crypto-asset belongs to, defined by its shared fundamental characteristics or a unified regulatory or framework alignment. Within the "Type" filter, users are also able to filter according to:
  * **Subtype**, which describes further subdivisions within a primary type, characterized by nuanced distinctions in functionality, utility, or alignment with specific environmental initiatives.&#x20;

{% hint style="warning" %}
It is crucial to note that our demarcation between types and subtypes does not adhere to strictly delineated boundaries. For example, various subtypes of environmental process tokens could potentially be consolidated into a singular type.&#x20;
{% endhint %}

* **Issuer,** which refers to the entity which was responsible for issuing the green asset. In certain circunstances (i.e. when the green asset is not yet onchain) "issuer" corresponds to the "producer" type of [green crypto value chain stakeholder](../project/solution/stakeholders), but in all other cases (i.e. when the green asset is onchain), it corresponds to the "tokenizer" type of [stakeholder](../project/solution/stakeholders).
* **Chain,** which refers to the different blockchain networks listed green assets are live on.
