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

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

ParameterTypeDescription
depositorPublicKeyThe depositor’s wallet public key
lpAmountbigint | numberAmount of LP tokens to lock for withdrawal

​
Optional Parameters

ParameterTypeDescription
tokenLpSrcPublicKeySource LP token account. Defaults to the depositor’s ATA for the LP mint
tokenLpEscrowPublicKeyLP token escrow PDA. Defaults to the vault’s LP escrow
tokenProgramPublicKeyToken program. Defaults to TOKEN_PROGRAM_ID
systemProgramPublicKeySystem 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.
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.
