# Adding liquidity to pools on Sonic

To provide liquidity to **Sonic** pools:

* Select the pool where you want to transfer liquidity, e.g., **xsArbitrum**.
* Determine the required token amounts.

{% hint style="success" %}
*For the **Arbitrum** example, you need 25% **frxUSD** and 25% **scUSD** to obtain 50% **xfrxUSD** and 50% **sUSDC\_arb** (percentages are based on the total liquidity you plan to transfer to the **xsArbitrum** pool).*
{% endhint %}

* Obtain the synthetic token for this direction, in this case, [**sUSDC\_arb**](https://docs.crosscurve.fi/user-documentation/migration-to-sonic/liquidity-transfer-from-fantom-to-sonic#obtaining-susdc_arb).
* For **USD** pools, acquire [**xfrxUSD** ](https://docs.crosscurve.fi/user-documentation/migration-to-sonic/liquidity-transfer-from-fantom-to-sonic#obtaining-xfrxusd-via-the-curve-app-interface)tokens. For example, deposit an equal amount of [**frxUSD** ](https://docs.crosscurve.fi/user-documentation/migration-to-sonic/liquidity-transfer-from-fantom-to-sonic#obtaining-frxusd-on-sonic-using-crosscurve-and-frax-bridge)and [**scUSD** ](https://docs.crosscurve.fi/user-documentation/migration-to-sonic/liquidity-transfer-from-fantom-to-sonic#obtaining-scusd-on-sonic-using-crosscurve-and-rings-app)into the [**CrossCurve frxUSD**](https://curve.finance/dex/sonic/pools/factory-stable-ng-25/deposit/) pool.
* Deposit the **universal token** and the **directional (synthetic) token** into the paired pool.

Let's examine each step:

### **1. Obtaining xfrxUSD via the Curve App interface** <a href="#obtaining-xfrxusd-via-the-curve-app-interface" id="obtaining-xfrxusd-via-the-curve-app-interface"></a>

To obtain the LP token **xfrxUSD**, you need to provide liquidity in the [**CrossCurve frxUSD**](https://curve.finance/dex/sonic/pools/factory-stable-ng-25/deposit/) pool:[ https://curve.finance/dex/sonic/pools/factory-stable-ng-25/deposit/](https://curve.finance/dex/sonic/pools/factory-stable-ng-25/deposit/).

Go to the [CrossCurve frxUSD](https://curve.finance/dex/sonic/pools/factory-stable-ng-25/deposit/) pool page and connect your wallet.

Enter the desired deposit amount on the **Deposit** tab. To avoid losses due to slippage, it’s recommended to deposit funds in a balanced manner by clicking **Add all coins in a balanced proportion** (learn more [here](https://docs.crosscurve.fi/user-documentation/liquidity-interface/liquidity-provision-use-cases/curve-knowledge-database/balanced-liquidity-provision)).

In the first transaction, confirm the spending of funds by clicking **Approve Spending** and signing the transaction in your wallet.

In the second transaction, deposit the funds by clicking **Deposit** and signing the transaction in your wallet.

After the transaction is successfully confirmed on-chain, your wallet will display the amount of received **xfrxUSD** LP tokens.

{% hint style="success" %}
*If your wallet doesn’t support automatic token addition, add it manually as a custom token with the contract address* [*0xf1232a1ab5661abdd6e02c6d8ac9940a23bb0b84* ](https://sonicscan.org/address/0xf1232a1ab5661abdd6e02c6d8ac9940a23bb0b84)*on the **Sonic** network.*
{% endhint %}

### 2. Obtaining sUSDC\_arb <a href="#obtaining-susdc_arb" id="obtaining-susdc_arb"></a>

**sUSDC\_arb** tokens on the **Sonic** network can be swapped from any available asset in the **xsArbitrum** pool via the [CrossCurve](https://app.crosscurve.fi/liquidity?pool=0x440bcab62d629ba60ca56b80e565636e0c404e60\&type=curve\&action=deposit\&output=0xd3dce716f3ef535c5ff8d041c1a41c3bd89b97ae\&chainOut=146) app.

1. Navigate to the **Liquidity** tab in the **Yield** section. Select the **Balanced mode** and click **Next**.
