# Price Feed

{% hint style="info" %}
**Good to know:** this contract manages the HEX/DAI from ETH price feed that is required to know the USD value of each HEX deposited as t-share.
{% endhint %}

## How the price feed works?

The price oracle is composed of 5 different price feeds:

* DAI from Ethereum-WPLS LP
* USDC from Ethereum-WPLS LP
* WETH from Ethereum-WPLS LP
* USDT from Ethereum-WPLS LP
* HEX-WPLS LP

Each of the price feed comes from PulseX v1. Most of the liquidity on-chain is linked to these pools, which means any sort of direct price-feed attack is highly unlikely. 

The price feed contract can be called by any participant and yields a reward that is based on the formula below. It describes that each time the price feed update is run, it yields 25,555 HEXIT tokens per second, times the total number of seconds between updates.

#### `(CurrentTimeSeconds- LastUpdateSeconds) * 25,555`

The price feed can be run by a bot. The contract can be accessed at [Hex One Protocol Git Hub](https://github.com/HexOneProtocol/hex1-contracts).
