Queue Withdrawal - Exponent Docs

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

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.

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.
