# Configuring Your Policies

## Configuring Policies for OpenTrade Vaults

Fireblocks has a powerful Policy engine which sets rules governing your interactions with both internal and external addresses and contracts. 

At a minimum, most Fireblocks workspaces prohibit interactions with non-whitelisted addresses, so you must first whitelist OpenTrade contract addresses via the process above. Once whitelisted, you can configure Policies that governs interactions with those whitelisted addresses. 

Fireblocks will consider interactions with OpenTrade as Contract Calls. At a minimum, your Policies must allow for Approve Transactions and Contract Calls with the OpenTrade contract addresses you've whitelisted. 

The guide below shows a basic rule configuration for interacting with OpenTrade Loan Vaults.

{% hint style="warning" %}
There are many other possible rules and combinations of rules you could configure which depend largely on other Policies you may have already configured in your workspace. **It is your sole responsibility to ensure the safety and security of your workspace's Policies.**
