# Wrapper Withdraw

> Withdraw a Senior or Junior tranche position back to base assets

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

## Usage

```typescript theme={null}
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]);
```

## Returns

* `ixs` - Instructions that perform tranche withdrawal, SY redemption, and flavor-specific pre/post steps
* `setupIxs` - Associated token account setup instructions for LP, SY, and base token accounts

<Warning>
  Senior withdrawals are only allowed while the market is `Active`. Junior withdrawals can run during `Active` or `FixedTermRecovery`, but cannot reduce coverage beyond the market's allowed utilization.
