# Add Liquidity

You can add liquidity to an existing pool in two different ways:

1. Double-asset: Depositing liquidity for both assets of the token pair
2. Single-asset: Depositing liquidity for the asset with less liquidity, further balancing out the pool 

### #1 Double Asset Deposit

1. Select the desired token pair

2. Input the desired liquidity. The swap ratio (marginal price) is located under the pool ratio.&#x20;

3. Review Pool Information. Select Supply.&#x20;

You have added liquidity to the pool and will receive minted LP share tokens that represent an ownership stake of the pool.&#x20;

### #2 Single Asset Deposit

Users can earn LP shares by depositing single-asset liquidity when a pool is unbalanced (when one reservoir holds tokens). The UI will show 'Token Imbalance' once an imbalanced token pair is selected. (Note: Users can continue to add double-sided liquidity to imbalanced pair as long as the deposits are in proportion to the swap ratio).&#x20;

1. If the pool is unbalanced (meaning one reservoir > 0), the UI will show a Token Imbalance. Press 'Done' to continue.&#x20;

2. To deposit single-sided liquidity, press toggle to Balance Pool.&#x20;

3. Enter the desired input amount. The Max deposit results in a balanced pool, and two empty reservoirs.&#x20;
