# Queue Withdrawal

> Lock LP tokens and queue a withdrawal request from the vault

The `ixQueueWithdrawal` method builds a transaction instruction that moves LP tokens into escrow and creates a withdrawal account — the first step in the two-phase withdrawal process.

## Usage

```typescript theme={null}
import { ExponentVault } from "@exponent-labs/exponent-sdk";
import { Connection, Transaction, sendAndConfirmTransaction } from "@solana/web3.js";
const connection = new Connection("https://api.mainnet-beta.solana.com");
const vault = await ExponentVault.load({ connection, address: vaultAddress });

const { ix, withdrawalKeypair } = vault.ixQueueWithdrawal({
  depositor: wallet.publicKey,
  lpAmount: 500_000_000n,
});

// The withdrawalKeypair must be included as a signer
const tx = new Transaction().add(ix);
await sendAndConfirmTransaction(connection, tx, [wallet, withdrawalKeypair]);

// Save this address — you'll need it to execute the withdrawal
const withdrawalAddress = withdrawalKeypair.publicKey;
```

## Required Parameters

| Parameter   | Type               | Description                                |
| ----------- | ------------------ | ------------------------------------------ |
| `depositor` | `PublicKey`        | The depositor's wallet public key          |
| `lpAmount`  | `bigint \| number` | Amount of LP tokens to lock for withdrawal |

## Optional Parameters

| Parameter       | Type        | Description                                                              |
| --------------- | ----------- | ------------------------------------------------------------------------ |
| `tokenLpSrc`    | `PublicKey` | Source LP token account. Defaults to the depositor's ATA for the LP mint |
| `tokenLpEscrow` | `PublicKey` | LP token escrow PDA. Defaults to the vault's LP escrow                   |
| `tokenProgram`  | `PublicKey` | Token program. Defaults to `TOKEN_PROGRAM_ID`                            |
| `systemProgram` | `PublicKey` | System program. Defaults to `SystemProgram.programId`                    |

## Returns

Returns `{ ix: TransactionInstruction, withdrawalKeypair: Keypair }`.

* `ix` — the instruction that creates the withdrawal account and moves LP tokens to escrow
* `withdrawalKeypair` — a freshly generated keypair whose public key is the withdrawal account address. Must be passed as a signer in the transaction.

## Next Step

After queuing, the vault manager calls `fillWithdrawal` to associate the underlying token accounts with your request. Once filled, call [`executeWithdrawal`](/vault-sdk/typescript/vault-operations/execute-withdrawal).

<Warning>
  Save the `withdrawalKeypair.publicKey` — you need it when calling `executeWithdrawal`. If lost, you can recover it by querying withdrawal accounts for your vault via RPC.
