Combine multiple borrow operations into one transaction. Pass both colAmount and debtAmount in a single getOperateIx call to batch operations (e.g. deposit + borrow, or repay + withdraw). When positionId is 0, the first call creates a new position and returns positionId for use in the second call. Transactions use versioned (v0) format with address lookup tables.

Combined operations

1

Import Dependencies

Import the required packages for Solana RPC, Jupiter Lend borrow SDK, and versioned transaction building.
import {
  Connection,
  Keypair,
  TransactionMessage,
  VersionedTransaction,
} from "@solana/web3.js";
import BN from "bn.js";
import { getOperateIx } from "@jup-ag/lend/borrow";
import fs from "fs";
import path from "path";
Combined operations use multiple getOperateIx calls. Pass both colAmount and debtAmount in one call to batch deposit + borrow or repay + withdraw.

Load Keypair and Initialise Connection

Load the signer and create the RPC connection. Set vault ID and amounts for each operation.
const KEYPAIR_PATH = "/path/to/your/keypair.json";
const RPC_URL = "https://api.mainnet-beta.solana.com";
const VAULT_ID = 1;

// Amounts in base units (e.g. USDC 6 decimals: 1_000_000 = 1 USDC)
const DEPOSIT_AMOUNT = new BN(1_000_000);
const BORROW_AMOUNT = new BN(500_000);
const REPAY_AMOUNT = new BN(100_000);
const WITHDRAW_AMOUNT = new BN(200_000);

function loadKeypair(keypairPath: string): Keypair {
  const fullPath = path.resolve(keypairPath);
  const secret = JSON.parse(fs.readFileSync(fullPath, "utf8"));
  return Keypair.fromSecretKey(new Uint8Array(secret));
}

const userKeypair = loadKeypair(KEYPAIR_PATH);
const connection = new Connection(RPC_URL, { commitment: "confirmed" });
const signer = userKeypair.publicKey;

Build Operate Instructions

Call getOperateIx twice: once with positionId: 0 to create a position and deposit + borrow; once with the returned positionId to repay + withdraw. Then merge instructions and address lookup tables.
// 1. Create position + Deposit + Borrow (positionId 0 creates new position)
const { ixs: depositBorrowIxs, addressLookupTableAccounts: depositBorrowAlts, positionId } = await getOperateIx({
  vaultId: VAULT_ID,
  positionId: 0,
  colAmount: DEPOSIT_AMOUNT,
  debtAmount: BORROW_AMOUNT,
  connection,
  signer,
});

// 2. Repay + Withdraw (use positionId from first call)
const repayWithdrawResult = await getOperateIx({
  vaultId: VAULT_ID,
  positionId: positionId!,
  colAmount: WITHDRAW_AMOUNT.neg(),
  debtAmount: REPAY_AMOUNT.neg(),
  connection,
  signer,
});

// Merge instructions and address lookup tables
const allIxs = [
  ...(depositBorrowIxs ?? []),
  ...(repayWithdrawResult.ixs ?? []),
];

const allAlts = [
  ...(depositBorrowAlts ?? []),
  ...(repayWithdrawResult.addressLookupTableAccounts ?? []),
];
const seenKeys = new Set<string>();
const mergedAlts = allAlts.filter((alt) => {
  const k = alt.key.toString();
  if (seenKeys.has(k)) return false;
  seenKeys.add(k);
  return true;
});

if (!allIxs.length) {
  throw new Error("No instructions returned.");
}
When positionId is 0, the SDK creates a new position and returns positionId. Use that positionId in the second call. Deduplicate address lookup tables by key when merging.

Build and Sign Transaction

Build a v0 message with the merged instructions and address lookup tables, then sign.
const latestBlockhash = await connection.getLatestBlockhash();
const message = new TransactionMessage({
  payerKey: signer,
  recentBlockhash: latestBlockhash.blockhash,
  instructions: allIxs,
}).compileToV0Message(mergedAlts);

const transaction = new VersionedTransaction(message);
transaction.sign([userKeypair]);
5

Send and Confirm Transaction

Send the transaction and confirm.
const signature = await connection.sendTransaction(transaction, {
  skipPreflight: false,
  maxRetries: 3,
  preflightCommitment: "confirmed",
});
await connection.confirmTransaction({ signature, ...latestBlockhash }, "confirmed");

console.log("Combined operate successful! Signature:", signature);

​
Operate parameters

getOperateIx accepts the following parameters:
ParameterTypeDescription
vaultIdnumberTarget vault (market) ID.
positionIdnumberPosition NFT ID. Use 0 to create a new position and operate in one transaction.
colAmountBNSigned collateral amount in base units. Positive = deposit. Negative = withdraw. Use new BN(0) for borrow/repay-only.
debtAmountBNSigned debt amount in base units. Positive = borrow. Negative = repay. Use new BN(0) for deposit/withdraw-only.
connectionConnectionSolana RPC connection.
signerPublicKeyWallet that signs the transaction (position owner).
Combine operations by passing both colAmount and debtAmount in one call (e.g. deposit + borrow: both positive; repay + withdraw: both negative).
Pass both colAmount and debtAmount in a single getOperateIx call to batch two operations. Deposit + borrow: colAmount > 0, debtAmount > 0. Repay + withdraw: colAmount < 0, debtAmount < 0.
If you already have a position, use its positionId instead of 0 in the first call and skip the create step. Or use positionId: positionId for both calls when doing repay + withdraw only.
