# Adding a Policy Book

## What is a Policy Book?

It's a contract that any DEIN user can create. It contains the Collateral and necessary information, mainly about all Policies bought for this pool and the insured contract.

## Who can set up a Policy Book?

Anyone can set up a Policy Book easily on the app. Once the user has specified the network, contract type, and the insured address, they can create a new pool by depositing 100 USDT or more. All users will be able to see the pool that has been created.

Although anyone can create a Policy Book, not all Policy Books are eligible to receive DEIN rewards for providing coverage to the pool. Only Whitelisted pools are eligible to receive DEIN rewards. This is done to prevent exploits of the protocol. Currently, whitelisting is done by the Bridge Mutual team, and later on, it will be done by the DEIN DAO.  

*Whitelisted pools have a small blue icon with a tick mark next to their name.* <img src="/files/whCdbgoZx2B23zSdAAZz" alt="" data-size="line">

## What chains does DEIN support?

DEIN is omni-chain. It supports almost every chain in existence. You only need a chain of your choice, and the corresponding contract address - DEIN will do the rest and find all available networks your project exists on.

## How does DEIN finds my project?&#x20;

We utilize the contract address and network information submitted by the user through the "Add Project" form to access the CoinGecko API database, allowing us to retrieve project addresses across various blockchain networks.
