createQueueWithdrawalInstruction

Builds a raw instruction to queue a withdrawal from a Strategy Vault. The depositor’s LP tokens are locked in escrow and a withdrawal account is created to track the request. The withdrawal must later be filled by the vault manager and then executed to receive underlying tokens. Called by depositors who want to withdraw from the vault.

​
Usage

import { createQueueWithdrawalInstruction } from "@exponent-labs/exponent-sdk/client/vaults";
import { Keypair, PublicKey } from "@solana/web3.js";

const withdrawalAccountKeypair = Keypair.generate();

const ix = createQueueWithdrawalInstruction(
  {
    depositor: wallet.publicKey,
    vault: vaultAddress,
    exponentPrices: exponentPricesPda,
    withdrawalAccount: withdrawalAccountKeypair.publicKey,
    tokenLpSrc: depositorLpTokenAccount,
    tokenLpEscrow: vaultLpEscrowAccount,
    tokenProgram: TOKEN_PROGRAM_ID,
    systemProgram: SYSTEM_PROGRAM_ID,
  },
  {
    lpAmount: BigInt(500_000),
    withdrawalType: { token: {} },
  }
);
