# How to Add/Remove Liquidity

***Liquidity*** is essential how Decentralized Exchanges like [9inch](https://app.9inch.io/) or PulseX work. You can add liquidity by binding two tokens and "staking" them in the [Liquidity](https://app.9inch.io/liquidity) page.

In return for providing liquidity, you will earn trading fees on that pair and receive Nine Inch LP tokens (NINE LP), that you can stake in the [Farms](https://app.9inch.io/farms) to earn $[BBC](https://9inch.gitbook.io/9inch-gitbook/tokenomics/bbc-token) token as reward.

In this section you will learn how to [add](#add-liquidity) and [remove](#remove-liquidity) liquidity on 9inch.

### Add liquidity

Go to the [**Liquidity**](https://app.9inch.io/liquidity) page.

<details>

<summary>Note</summary>

Your liquidity pairs will show up here under **Your Liquidity.**

Unique user friendly feature of 9inch, if you stake your LP to a [Farm](https://9inch.gitbook.io/9inch-gitbook/tips-tricks-and-guides/beginners-guide-to-defi/how-to-use-farms), you will still be able to see and access the LP from Liquidity page. It will have a "staked" notion on the LP when it is deployed into a Farm.

Click **\[Add Liquidity]**

<div align="left"><figure><img src="https://747412000-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fi561wEeRIxQAdQvqesSN%2Fuploads%2FiFmQY5Kj7wzGinZp0hbi%2Fimage.png?alt=media&#x26;token=a512ff45-5e7b-44d3-8de2-7fe6161c1991" alt="" width="341"><figcaption></figcaption></figure></div>

Next, from the drop down menus, select the desired token pair you want to provide liquidity for.

Here in this example ETH and [BBC](https://9inch.gitbook.io/9inch-gitbook/tokenomics/bbc-token).

Input the desired amounts to provide.

Here it was chosen to provide 1000 $BBC and $ETH ratio was automatically calculated.

<details>

<summary>If you are new to LP read this!</summary>

You can input an amount on either one of the text fields. If there is already liquidity for that pair, the other field will be automatically estimated.

If you are the first liquidity provider, you get to choose the ratio, or value between the tokens and you need to input a value in both fields.

Please take into consideration token prices when you provide new pairs. If your price ratio is not in line with other LP pairs, your LP might get bought by MEV bots until the token ratios match the price in other LP pairs. This could lead to impermanent loss.
