# Withdraw Liquidity to Base

> Withdraw an LP position back to base assets in a single transaction

The `ixWithdrawLiquidityToBase` method on the `MarketThree` class withdraws liquidity from the CLMM pool and converts it back to base assets. It removes liquidity (collecting accrued fees), merges PT and YT back into SY, and redeems SY for the base asset in a single atomic operation.

## Usage

```typescript theme={null}
import { MarketThree, LOCAL_ENV } from "@exponent-labs/exponent-sdk";
import { Connection, PublicKey, Transaction, sendAndConfirmTransaction } from "@solana/web3.js";

const connection = new Connection("https://api.mainnet-beta.solana.com");
const market = await MarketThree.load(LOCAL_ENV, connection, marketAddress);

const { ixs, setupIxs } = await market.ixWithdrawLiquidityToBase({
  owner: wallet.publicKey,
  amountLp: 9_000_000_000n,
  minBaseOut: 8_500_000_000n,
  lpPosition: lpPositionPublicKey,
});

const tx = new Transaction().add(...setupIxs, ...ixs);
const signature = await sendAndConfirmTransaction(connection, tx, [wallet]);
```

<Note>
  The `lpPosition` parameter is the public key of your LP position account. Use `market.getUserLpPositions()` to retrieve your positions.
</Note>
