Wrapper Withdraw - Exponent Docs

The ixWrapperWithdraw instruction burns tranche LP shares, withdraws SY from the market, and redeems SY back to the base asset.

Usage

import { Transaction, sendAndConfirmTransaction } from "@solana/web3.js";
import { TrancheSide } from "@exponent-labs/exponent-sdk/client/tranching";

const { ixs, setupIxs } = await market.ixWrapperWithdraw({
  user: wallet.publicKey,
  trancheSide: TrancheSide.Senior,
  lpAmountIn: 500_000_000n, // raw Senior LP units to burn
  minBaseOut: 0n,           // raw base-token units; set above 0 for output protection
});

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