Jupiter Lend Earn instructions

Use these instructions when your strategy vault should deposit underlying tokens into Jupiter Lend Earn jlToken vaults. For Jupiter’s collateralized borrowing product, see Jupiter Lend Borrow instructions. Jupiter Earn exposes eight on-chain operations split into two account groups:

Asset-in (deposit / mint variants) — vault sends the underlying token, receives jlTokens.
Asset-out (withdraw / redeem variants) — vault sends jlTokens, receives the underlying token.

The SDK provides one raw createJupiterEarn*Instruction(...) per op and matching jupiterEarnAction.<method>(...) wrappers that register the op as a vault step.

Transaction structure

Every Jupiter Earn action goes through createVaultSyncTransaction.

import {
  createVaultSyncTransaction,
  createJupiterEarnDepositInstruction,
  jupiterEarnAction,
} from "@exponent-labs/exponent-sdk";
import { Transaction, sendAndConfirmTransaction } from "@solana/web3.js";

const depositIx = createJupiterEarnDepositInstruction(assetInAccounts, 50_000_000n);

const { setupInstructions, preInstructions, instruction, postInstructions } =
  await createVaultSyncTransaction({
    instructions: [
      jupiterEarnAction.deposit({ instruction: depositIx }),
    ],
    owner: vaultPda,
    connection,
    policyPda,
    vaultPda,
    signer: wallet.publicKey,
    vaultAddress,
  });

const tx = new Transaction().add(
  ...setupInstructions,
  ...preInstructions,
  instruction,
  ...postInstructions,
);
await sendAndConfirmTransaction(connection, tx, [wallet]);

Part	What it contains
`setupInstructions`	Setup instructions that must run before refreshes or the sync step
`preInstructions`	Permissionless refresh instructions that must run before the sync step
`instruction`	The Squads sync transaction instruction wrapping the vault-signed Jupiter Earn action
`postInstructions`	Permissionless refresh instructions that must run after the sync step

Asset-in accounts

All four asset-in operations (deposit, depositWithMinAmountOut, mint, mintWithMaxAssets) share the same JupiterEarnAssetInAccounts shape. Build it once and pass it into each instruction builder.

import type { JupiterEarnAssetInAccounts } from "@exponent-labs/exponent-sdk";
import { TOKEN_PROGRAM_ID } from "@solana/spl-token";

const assetInAccounts: JupiterEarnAssetInAccounts = {
  signer: vaultPda,                          // Squads vault PDA — the trader signing through the policy
  depositorTokenAccount: vaultUnderlyingAta, // Vault's underlying token ATA (e.g., USDC)
  recipientTokenAccount: vaultJlTokenAta,    // Vault's jlToken ATA (will receive the receipt)
  mint: USDC_MINT,                           // Underlying token mint
  lendingAdmin: JUPITER_LENDING_ADMIN,
  lending: JUPITER_EARN_USDC_LENDING_ID,
  fTokenMint: JUPITER_EARN_USDC_JL_TOKEN_MINT_ID,
  supplyTokenReservesLiquidity: JUPITER_LEND_SUPPLY_TOKEN_RESERVES_LIQUIDITY_ID,
  lendingSupplyPositionOnLiquidity: JUPITER_LEND_LENDING_SUPPLY_POSITION_ON_LIQUIDITY_ID,
  rateModel: JUPITER_LEND_RATE_MODEL_ID,
  vault: JUPITER_LEND_VAULT_ID,
  liquidity: JUPITER_LEND_LIQUIDITY_ID,
  liquidityProgram: JUPITER_LENDING_POOLS_PROGRAM_ID,
  rewardsRateModel: JUPITER_LEND_REWARDS_RATE_MODEL_ID,
  tokenProgram: TOKEN_PROGRAM_ID,
};

buildJupiterLendPriceInterfaceAccounts(accounts) returns the price-interface AccountMeta[] Jupiter expects for downstream price reads, derived from the same accounts struct.

Deposit

createJupiterEarnDepositInstruction(accounts, assets) deposits an exact amount of underlying tokens and receives jlTokens at the current rate. createJupiterEarnDepositWithMinAmountOutInstruction(accounts, assets, minAmountOut) is the same operation with a slippage floor on the jlTokens received.

import {
  createJupiterEarnDepositInstruction,
  createJupiterEarnDepositWithMinAmountOutInstruction,
  jupiterEarnAction,
} from "@exponent-labs/exponent-sdk";

// Plain deposit
const depositIx = createJupiterEarnDepositInstruction(assetInAccounts, 50_000_000n);

// Deposit with slippage floor
const depositMinIx = createJupiterEarnDepositWithMinAmountOutInstruction(
  assetInAccounts,
  50_000_000n,   // assets to deposit
  49_500_000n,   // minimum jlTokens to receive
);

// Wrap as a vault step
jupiterEarnAction.deposit({ instruction: depositIx });
jupiterEarnAction.depositWithMinAmountOut({ instruction: depositMinIx });

Parameters

Name	Type	Description
`accounts`	`JupiterEarnAssetInAccounts`	Asset-in account set
`assets`	`bigint \| number \| string \| BN`	Underlying token amount in atomic units
`minAmountOut`	`bigint \| number \| string \| BN`	With-min variant only. Minimum jlTokens to receive — slippage floor

Mint

createJupiterEarnMintInstruction(accounts, shares) mints an exact amount of jlTokens, paying the current required underlying. createJupiterEarnMintWithMaxAssetsInstruction(accounts, shares, maxAssets) adds a cap on the underlying spent.

import {
  createJupiterEarnMintInstruction,
  createJupiterEarnMintWithMaxAssetsInstruction,
  jupiterEarnAction,
} from "@exponent-labs/exponent-sdk";

const mintIx = createJupiterEarnMintInstruction(assetInAccounts, 5_000_000n);

const mintMaxIx = createJupiterEarnMintWithMaxAssetsInstruction(
  assetInAccounts,
  5_000_000n,    // jlTokens to mint
  5_100_000n,    // maximum underlying to spend
);

jupiterEarnAction.mint({ instruction: mintIx });
jupiterEarnAction.mintWithMaxAssets({ instruction: mintMaxIx });

Parameters

Name	Type	Description

`shares`	`bigint \| number \| string \| BN`	jlToken amount to mint, in atomic units
`maxAssets`	`bigint \| number \| string \| BN`	With-max variant only. Maximum underlying spend cap

Asset-out accounts

The four asset-out operations (withdraw, withdrawWithMaxSharesBurn, redeem, redeemWithMinAmountOut) share JupiterEarnAssetOutAccounts. The shape mirrors asset-in, with the source/recipient roles flipped.

import type { JupiterEarnAssetOutAccounts } from "@exponent-labs/exponent-sdk";

const assetOutAccounts: JupiterEarnAssetOutAccounts = {
  signer: vaultPda,                          // Squads vault PDA
  ownerTokenAccount: vaultJlTokenAta,        // Vault's jlToken ATA — the source
  recipientTokenAccount: vaultUnderlyingAta, // Vault's underlying ATA — receives the unwound underlying
  lendingAdmin: JUPITER_LENDING_ADMIN,
  lending: JUPITER_EARN_USDC_LENDING_ID,
  mint: USDC_MINT,
  fTokenMint: JUPITER_EARN_USDC_JL_TOKEN_MINT_ID,
  supplyTokenReservesLiquidity: JUPITER_LEND_SUPPLY_TOKEN_RESERVES_LIQUIDITY_ID,

  claimAccount: JUPITER_CLAIM_ACCOUNT,
  tokenProgram: TOKEN_PROGRAM_ID,
};

Withdraw

createJupiterEarnWithdrawInstruction(accounts, amount) withdraws an exact amount of underlying by burning the implied jlTokens at the current rate. createJupiterEarnWithdrawWithMaxSharesBurnInstruction(accounts, amount, maxSharesBurn) adds a cap on the jlTokens burned.

import {
  createJupiterEarnWithdrawInstruction,
  createJupiterEarnWithdrawWithMaxSharesBurnInstruction,
  jupiterEarnAction,
} from "@exponent-labs/exponent-sdk";

const withdrawIx = createJupiterEarnWithdrawInstruction(assetOutAccounts, 25_000_000n);

const withdrawMaxIx = createJupiterEarnWithdrawWithMaxSharesBurnInstruction(
  assetOutAccounts,
  25_000_000n,   // underlying to withdraw
  26_000_000n,   // maximum jlTokens to burn
);

jupiterEarnAction.withdraw({ instruction: withdrawIx });
jupiterEarnAction.withdrawWithMaxSharesBurn({ instruction: withdrawMaxIx });

Parameters

Name	Type	Description

`amount`	`bigint \| number \| string \| BN`	Underlying amount to withdraw, in atomic units
`maxSharesBurn`	`bigint \| number \| string \| BN`	With-max variant only. Maximum jlTokens burn cap

Redeem

createJupiterEarnRedeemInstruction(accounts, shares) redeems an exact amount of jlTokens for underlying at the current rate. createJupiterEarnRedeemWithMinAmountOutInstruction(accounts, shares, minAmountOut) adds a slippage floor on the underlying received.

import {
  createJupiterEarnRedeemInstruction,
  createJupiterEarnRedeemWithMinAmountOutInstruction,
  jupiterEarnAction,
} from "@exponent-labs/exponent-sdk";

const redeemIx = createJupiterEarnRedeemInstruction(assetOutAccounts, 5_000_000n);

const redeemMinIx = createJupiterEarnRedeemWithMinAmountOutInstruction(
  assetOutAccounts,
  5_000_000n,    // jlTokens to redeem
  4_950_000n,    // minimum underlying to receive
);

jupiterEarnAction.redeem({ instruction: redeemIx });
jupiterEarnAction.redeemWithMinAmountOut({ instruction: redeemMinIx });

Parameters

Action wrappers

Every Earn op has a matching jupiterEarnAction.<method> that registers the raw instruction as a vault step. All wrappers take a single { instruction } object.

Wrapper	Pairs with
`jupiterEarnAction.deposit`	`createJupiterEarnDepositInstruction`
`jupiterEarnAction.depositWithMinAmountOut`	`createJupiterEarnDepositWithMinAmountOutInstruction`
`jupiterEarnAction.mint`	`createJupiterEarnMintInstruction`
`jupiterEarnAction.mintWithMaxAssets`	`createJupiterEarnMintWithMaxAssetsInstruction`
`jupiterEarnAction.withdraw`	`createJupiterEarnWithdrawInstruction`
`jupiterEarnAction.withdrawWithMaxSharesBurn`	`createJupiterEarnWithdrawWithMaxSharesBurnInstruction`
`jupiterEarnAction.redeem`	`createJupiterEarnRedeemInstruction`
`jupiterEarnAction.redeemWithMinAmountOut`	`createJupiterEarnRedeemWithMinAmountOutInstruction`

Constants

Constant	Description
`JUPITER_LEND_EARN_PROGRAM_ID`	Jupiter Lend Earn program: `jup3YeL8QhtSx1e253b2FDvsMNC87fDrgQZivbrndc9`

For policy authoring or custom data-constraint work, the SDK also exports JUPITER_EARN_DISCRIMINATORS (per-action discriminators) and JUPITER_EARN_ACCOUNT_INDICES (account-index maps for asset-in and asset-out paths). A matching policy must exist before executing. See Jupiter Lend Earn Policy.

Full flow example

This example deposits underlying into a Jupiter Earn vault, then unwinds with a redeem.

import {
  createVaultSyncTransaction,
  createJupiterEarnDepositInstruction,
  createJupiterEarnRedeemInstruction,
  jupiterEarnAction,
} from "@exponent-labs/exponent-sdk";
import { Transaction, sendAndConfirmTransaction } from "@solana/web3.js";

// Step 1: Deposit 50 USDC into the jlUSDC vault.
{
  const depositIx = createJupiterEarnDepositInstruction(assetInAccounts, 50_000_000n);
  const { setupInstructions, preInstructions, instruction, postInstructions } =
    await createVaultSyncTransaction({
      instructions: [jupiterEarnAction.deposit({ instruction: depositIx })],
      owner: vaultPda,
      connection,
      policyPda,
      vaultPda,
      signer: wallet.publicKey,
      vaultAddress,
    });
  const tx = new Transaction().add(
    ...setupInstructions,
    ...preInstructions,
    instruction,
    ...postInstructions,
  );
  await sendAndConfirmTransaction(connection, tx, [wallet]);
}

// Step 2: Redeem 5 jlUSDC back to underlying.
{
  const redeemIx = createJupiterEarnRedeemInstruction(assetOutAccounts, 5_000_000n);
  const { setupInstructions, preInstructions, instruction, postInstructions } =
    await createVaultSyncTransaction({
      instructions: [jupiterEarnAction.redeem({ instruction: redeemIx })],
      owner: vaultPda,
      connection,
      policyPda,
      vaultPda,
      signer: wallet.publicKey,
      vaultAddress,
    });
  const tx = new Transaction().add(
    ...setupInstructions,
    ...preInstructions,
    instruction,
    ...postInstructions,
