# Staking LP Tokens

In order to participate in Sumero's liquidity mining programs, users must stake their USDC-CLAY liquidity provider (LP) tokens.

The first action a user must take in order to begin participating is to *deposit* their USDC-CLAY LP tokens into the canonical USDC-CLAY staking contract, effectively temporarily giving custody over their stake in the liquidity pool to this contract. This is necessary because the staking contract needs to be able to guarantee that liquidity cannot be removed from LPs participating in the program.

Once deposited, staked LP tokens immediately start earning Clay rewards. Users may periodically claim accrued Clay rewards while the program is ongoing or claim once the program has concluded to minimize overhead. The reason your LP tokens earn Clay rewards while staked is that you are increasing the USDC and Clay liquidity of the Sumero protocol which enables the protocol to efficiently facilitate trades between USDC and Clay.

### How To Stake LP Tokens

* Ensure there is sufficient Clay and USDC in your wallet.

* Connect your wallet by clicking “Connect Wallet” in the top right corner. We recommend using the Metamask wallet.

* Go to the Sumero Pool page.&#x20;

* In the asset field, input the amount of CLAY you would like to deposit into the pool. USDC and the CLAY must be deposited in a [50/50 ratio](https://support.uniswap.org/hc/en-us/articles/7423702800141) in order to maintain equilibrium within the pool. In order to simplify this calculation, the corresponding amount of USDC required to open the position will be automatically populated.&#x20;

* When you are finished reviewing the respective pool trading fees, you are ready to submit the transaction. First, you may need to approve the Sumero router contract to allow the protocol to spend both of the selected tokens on your behalf. This is only necessary the first time you provide liquidity for each token. Click “Approve” so that you can deposit your USDC and CLAY tokens. Confirm the transaction in your wallet.&#x20;

### Summary

* Users provide liquidity to Sumero's USDC-CLAY pool.&#x20;
* Users receive USDC-CLAY LP tokens in return. These LP tokens represent their portion of the pooled assets.
* Users can then stake these USDC-CLAY LP tokens to earn Clay staking rewards.
