# Tanks

![](/files/-MaFDFmtr7sN2OO3fbnG)

## Introducing Tanks

The purpose of Tanks is to bring you the best single-asset pools available on Polygon.\
Our Tanks rewards are currently powered by the KRILL token. Our Tanks currently contain **7** Polywhale single asset pools, including the single KRILL pool.\
\
<https://polywhale.finance/tanks>

{% hint style="info" %}
❗️**Tank mechanisms:**\
\
🐋 KRILL - 0% fees.\
**🌎** WMATIC, WBTC, WETH, QUICK, USDT & USDC - 4% fee on deposits.\
🔥 75% of the fees are used to market buy KRILL and burn it.\
🐳 25% of the fee goes to the Polywhale Treasury.
{% endhint %}

We are currently updating the Tanks. Our yield aggregator will bring in external rewards, and the existing fee structure will change. Once the Tanks update is live, all Polywhale pools will be auto-compounding.

## 🐠Pools in our Tank

**We have created 7 powerful pools for various Polygon based assets.**\
**You can find these new pools in our** [**Tanks**](https://polywhale.finance/tanks)**.** \
\
We created the very first farm on Polygon. Our tanks possible for you to stake a variety of your favorite Polygon single assets. If you prefer to just stake for example KRILL tokens or MATIC tokens instead of staking LP tokens, these pools are for you.\
\
**These 7 pools below have been added to Tanks:**
