# Private Liquidity Provisioning

{% hint style="info" %}
[Uniswap v2 style pools](https://docs.uniswap.org/contracts/v2/concepts/core-concepts/pools) require equal value amounts of the underlying assets. Users deposit assets and receive Liquidity Pool (LP) tokens redeemable for the assets.
{% endhint %}

### Prerequisites

* You have a [created](https://help.railway.xyz/setup/create-wallet) or [imported](https://help.railway.xyz/setup/import-wallet) a wallet into Railway
* [Shielded](https://help.railway.xyz/transactions/shield-unshield) some assets into your 0zk balance

**Tip**: You can also farm LP tokens in the [Railway Farm](https://help.railway.xyz/integrated-dapps/private-yield-farming). Click 'Farm' and then a vault provider to see a list of farmable assets. Once you've selected a compatible vault you can then return to the 'Liquidity' tab to enter an LP.&#x20;
