The ixWithdrawLiquidity method on the MarketThree class redeems LP tokens for PT and SY. You specify the LP position to withdraw from, the amount of LP to burn, and minimum outputs for slippage protection.
This is a low-level method that returns PT and SY tokens. To withdraw directly to a base asset (e.g., USDC), use ixWithdrawLiquidityToBase or ixWithdrawLiquidityClassic instead.

​
Usage

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 } = market.ixWithdrawLiquidity({
  withdrawer: wallet.publicKey,
  lpIn: 9_000_000_000n,           // LP tokens to burn
  lpPosition: lpPositionPublicKey, // from getUserLpPositions
  minPtOut: 4_000_000_000n,       // minimum PT to receive
  minSyOut: 4_000_000_000n,       // minimum SY to receive
});

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