# Add Liquidity

Adding liquidity to **TrumpSwap** is an essential way for users to participate in and support the platform's ecosystem. Currently, Liquidity Providers can add liquidity to the **Trump47/ETH** pair on **TrumpSwap**. By doing so, you contribute to the liquidity pool, making token swaps between Trump47 and ETH smoother and more efficient.

To add liquidity, you need to deposit an equal value of **Trump47 tokens** and **ETH** into the pool. In return, you will receive **LP tokens (UNI-V2)**, which represent your share of the liquidity pool. These LP tokens also entitle you to a portion of the trading fees generated from swaps within the pool.

**The formula for calculating the number of LP tokens in an existing Trump47/ETH pool is:**

For example:

* If there are 1000 Trump47 tokens and 1000 ETH in the pool, and you are adding 100 Trump47 tokens and an equivalent value of ETH, you're adding 10% of the liquidity.
* If the total supply of LP tokens is 1000, you will receive 100 LP tokens (10% of the total LP tokens).

Adding liquidity not only supports the platform but also offers an opportunity to earn passive income through trading fees.
