Jupiter Launches Lend v2, Letting the Same Dollar Earn Lending and Trading Fees

Solana lending giant Jupiter has launched Lend v2, a product designed to let the same capital earn lending interest and a share of trading fees. The feature links lending returns to the amount of swap activity routed through Jupiter’s new liquidity vaults.

How Lend v2 Works

Lend v2 allows deposited assets and borrowed positions to simultaneously serve as trading liquidity. Users can opt into two features that combine lending with liquidity provision:

• Smart Collateral automatically pairs deposits of USDC, USDT, SOL or JupSOL in correlated liquidity pools.
• Smart Debt applies the same mechanism to borrowed assets, allowing trading fees to offset borrowing costs.

Depositors using Smart Collateral can earn interest on loans while also receiving swap fees and, where applicable, staking rewards. Borrowers using Smart Debt can potentially reduce the effective cost of their loans when traders route swaps through the relevant pools.

Users who prefer conventional lending can leave both options disabled. The additional return is not guaranteed: it depends on traders actually using the pools for swaps.

Jupiter operates one of Solana’s largest swap routers, the software used by wallets and applications to seek execution across trading venues. However, the company said its router does not favor its own vaults and directs trades wherever pricing is best.

Scale and Risk Controls

Jupiter Lend already holds approximately $1.9 billion in deposits, according to DefiLlama data, while active loans total about $822.7 million, based on Token Terminal figures. Deposits and loans have both declined over the past month, and active borrowing has fluctuated between $600 million and $900 million since September.

The protocol generated roughly $1.6 million in fees during the past 30 days, equivalent to about 1% annually on capital held before any protocol revenue split. Lend v2 aims to improve those economics by making lending positions productive in a second market.

The design is limited to correlated assets, including stablecoin pairs and SOL against its staked versions, rather than volatile-asset combinations. Jupiter said margin calculations use primary-market oracles, meaning temporary exchange price fluctuations should not immediately trigger liquidation.

A genuine depeg creates different outcomes for borrowers and collateral suppliers. A borrower with $100 split between USDC and USDT would remain responsible for $100 as the pool rebalances toward the asset retaining its value. A collateral provider, however, bears the loss on both assets if one of them breaks its peg.

What This Means

Lend v2 brings lending and exchange liquidity into a single position, potentially allowing Jupiter to offer higher deposit yields and cheaper borrowing. The model’s success will depend on whether Jupiter’s router can deliver sufficient swap volume without compromising execution quality.

Jupiter expects a mix of new loans and migrated positions but has not set a target or cap. With its loan book largely stagnant over the past year, the next 30 days of active-loan data should show whether enhanced yield can reignite growth. For users, the product offers greater capital efficiency—but also introduces liquidity-demand and depeg risks that ordinary lending does not carry.
