# Base & MetaPools

## **Plain Pools**

**Plain pools:** support 1 stablecoin and 1 non-stablecoin trading liquidity pool.

A plain pool is the simplest implementation of Torah, where all assets in the pool are ordinary ERC tokens.

One of the <mark style="color:red;">largest is TriPool</mark>, holding only the three biggest stable coins (USDC/USDT/DAI). It's a non-lending gas optimised pool similar to the sUSD one.

{% endcontent-ref %}

**In plain pools, your risks are as follow:**

* Smart contract issues with Torah
* Systemic issues with the stable coins in those pools

As you can see, risks are different which might make this pool a better choice for you depending on what your concerns in the cryptosphere are

## **MetaPools**

**Meta pools**: a liquidity pool composed of a stablecoin and a Base Pool. The purpose of this liquidity pool is to reuse the stablecoins with higher capital utilization and better pool depth in the Base Pool.

Metapools allow for one stable token to seemingly trade with another underlying base pool. This means we could create, for example, the BUSD metapool: \[BUSD, \[3Pool]].

In this example users could seamlessly trade BUSD between the three coins in the 3Pool (DAI/USDC/USDT). This is helpful in multiple ways:

Allows Torah to list less liquid assets

More volume and more trading fees for the DAO

The Metapool in question would take BUSD and 3Pool LP tokens. This means that liquidity providers of the 3Pool **who do not provide liquidity in the BUSD Metapool are shielded from systemic risks from the Metapool**.

Metapools will have a [deposit wrapped](https://torahdao.gitbook.io/torah-finance/troubleshooting/faqs) option to deposit the 3pool token.
