# Supply an insurance policy

### What is a policy supplier?

A policy supplier is a participant who deposits **denominated asset** to supply policy on the market. Anyone could do this if they are confident in the **underlying assets** price. Or official teams of the underlying assets, seeking to make coverage for their users by a reasonable price, will perform policy suppliers. 

**Please do keep in mind that if the policy you supply is bought, your original denominated asset can be swap to underlying asset by policy holder at any time during the insurance period.**

### Why should I be a policy supplier?

As a policy supplier, by publishing and selling a policy, you could get quick, upfront premium from buyers. If there is no holder activate the policy until expiration date, you can redeem your denominated asset back for all of your initial collateral (minus the redemption fee) and the premium will be your net profits. 

### How to Supply a policy?

Firstly, you need to deposit the denominated asset to publish a policy supplying advertisement; (Helmet contract supports any asset as denominated asset to sell insurance of asset X as long as there is a swap tool on the chain with price fixing capability or an exchange index that reflects the price of the market. If you want to supply A Token insurance policy by using B Token as denominated asset , you need to determine an exchange ratio between A Token& B Token and post it according to the trading liquidity.）

In order to protect users from liquidity attacks, at early stage, the team publishes insurance assets which can be traded based on the chain ecology. Helmet team will introduce more insurance instruments based on liquidity.
