# Add liquidity on Base

Add xSPACE and ETH to the Uniswap V3 pool on Base with the SPACE Liquidity UI, and get xSPACE LP tokens.

Uniswap V3 liquidity pools allow users to trade SPACE with other assets on Base. In this step-by-step guide, you will learn how to provide liquidity to the **ETH / xSPACE** pool with our SPACE Liquidity UI.

### Before you start

You need **xSPACE** and **ETH** in your Web3 wallet on the **Base** network.

We recommend using [Rabby.io](https://rabby.io/) as a Web3 wallet, since that's probably the most secure and the user experience is great.

### 1. Open the SPACE Liquidity UI

Go to <https://liquidity.spacetoken.tech/?chainId=8453>

### 2. Connect your Web3 wallet

Connect the Web3 wallet that contains your xSPACE and ETH on Base.

If you use Rabby, the UI will automatically switch to the Base network.

### 3. Enter the amount you want to add

You need to provide xSPACE and ETH in a \~50/50 ratio (for example, $3 of xSPACE and $3 of ETH).

Clicking the **Max** button will automatically fetch the maximum amount that you can add to the pool, according to your xSPACE and ETH balances.

### 4. Approve xSPACE

Approve xSPACE so the token can interact with the pool. This requires you to sign a transaction on your Web3 wallet; don't worry, it is safe.

### 5. Confirm the approval transaction

Sign the approval and wait for the network confirmation.

### Manage your position

Bookmark <https://liquidity.spacetoken.tech/positions>. From there you can, at any time:

* **Claim Fees** — collect the trading fees your position has earned. The position stays open and keeps earning.
* **Add Liquidity** — top up a position that is already live, instead of opening a second one.
* **Close Position** — withdraw both tokens together with the fees earned, in a single transaction.

{% hint style="info" %}
If you come back to the add-liquidity page while a position is already open, the UI detects it and shows **Existing position detected. Liquidity will be added to it.** The button then reads **Increase Liquidity**, so your liquidity is concentrated in that one position instead of being spread across several.
{% endhint %}

### 🎉 Congratulations!
