Jupiter launched Lend v2 on Solana on August 10, a lending upgrade that lets supplied and borrowed assets work as DEX liquidity while still in a lending position. It's the first lending protocol on Solana where borrowed assets can earn trading fees.
Two opt-in features
Lend v2 introduces Smart Collateral and Smart Debt. Both are optional, so users who prefer traditional lending can keep doing that. Smart Collateral composes a single supported asset — USDC, USDT, SOL, or JupSOL — into a correlated liquidity pair. Eligible deposits can earn lending yield, trading fees, and native staking rewards from one position.
Smart Debt lets borrowed assets function as DEX liquidity, with trading fees offsetting borrowing costs. The borrowing and repaying mechanics stay the same as before.
How the features work
With Smart Collateral, a user's deposit isn't just sitting idle. It's put to work in a liquidity pair that's correlated to the original asset. That means a SOL deposit could be paired with a stablecoin, for example, and earn from trading activity on top of lending interest. For JupSOL, staking rewards also come in.
Smart Debt flips the idea of borrowing on its head. Instead of paying interest on a loan, the borrowed assets are used as liquidity in a DEX pool. The trading fees generated from that pool go toward the borrowing cost. If fees are high enough, they could cover the interest entirely.
The COO's take
Kash Dhanda, COO of Jupiter, said Lend v2 brings down the wall between lending and LPing. That's the core idea: users no longer have to choose between earning yield on assets and providing liquidity. They can do both from the same position.
Jupiter also added a lifetime PnL tracker, so users can see a position's earnings and costs over its entire history. That gives a clearer picture of whether the new features are actually paying off.
Jupiter's growing footprint
Jupiter runs swaps, perpetuals, and lending on Solana. Its JupSOL token held $396.0 million in total value locked on August 10, according to DefiLlama. The perpetual futures venue held $702.6 million the same day.
The new lending features are live now. Users can opt in or stick with the old way. The question is how many will take the leap.
