# Pauser Role

The smart contracts used in the Teller Platform often have `Pauser/owner` variables to designate the party with special privileges to make modifications to the platform's settings. In the spirit of transparency in the decentralized world, these roles are documented below for the Teller Finance platform.

## Pauser Role

The `Pauser` role is set in the Settings smart contract for the Teller platform and inherited into the platform's smart contracts. 

{% hint style="info" %}
Ethereum wallet addresses are assigned `Pauser` role through the Teller Protocol to govern the management and development of the Teller Platform.
{% endhint %}

The Teller Protocol wallet addresses with the Pauser role can govern methods in the following contracts:
