Jupiter has launched Lend V2, a redesigned version of its Solana-based lending product that enables a single deposit to simultaneously earn interest as a loan and a share of trading fees. The upgrade comes as Jupiter, already Solana's largest DEX aggregator by trading volume, extends its reach deeper into the lending market where it competes with protocols like Kamino and MarginFi.

According to DefiLlama data cited in the announcement, Jupiter Lend currently holds approximately $1.9 billion in deposits and generated $1.6 million in fees over the past 30 days—roughly 1% annualized on the capital before any split with the protocol. Active loans on the platform stand at $822.7 million, a figure that has fluctuated between $600 million and $900 million since September. Both deposits and loans have declined over the past month, a trend Jupiter aims to reverse with this upgrade.

How Smart Collateral and Smart Debt Work

The new version introduces two optional features. Smart Collateral automatically pairs a deposit of USDC, USDT, SOL, or JupSOL into a correlated liquidity pool, allowing the asset to earn lending yield alongside trading fees and, where applicable, staking rewards—all from a single position.

Smart Debt mirrors this mechanism on the borrowing side: fees generated by a debt position offset the cost of the loan itself. Users who prefer plain lending can skip both features entirely, with no changes to their existing experience. The design reflects a broader trend in DeFi toward composable primitives that merge previously distinct functions—similar to how Curve's lending markets and other protocols have blurred the line between liquidity provision and borrowing.

Yield Depends on Jupiter's Own Router

The extra return only materializes if traders actually swap through the relevant pools. This places Jupiter in an unusual position: the company operates Solana's largest swap router—the tool most wallets use to find the best execution price—and now also owns the vaults that depend on that swap flow to generate payouts. The arrangement raises the same questions about vertical integration that have accompanied major DEX aggregators across multiple chains as they expand into adjacent revenue lines.

Jupiter told CoinDesk that the router does not favor its own vaults and routes trades wherever pricing is best. The company also stated that margin is priced using primary market oracles, meaning a temporary price wobble on a single exchange will not trigger a liquidation; positions close normally once loan-to-value ratios cross the threshold.

A genuine stablecoin depeg is handled differently depending on which side of the trade a user is on. Borrowers are protected: someone who owes $100 split across USDC and USDT would see the pool automatically rebalance into whichever asset held its value, still owing $100. Collateral suppliers, however, receive no such cushion and absorb losses on either asset if one breaks its peg. This is why Jupiter has confined the design to correlated pairs—stablecoins against each other, and SOL against its staked versions—rather than volatile assets.

Breaking Down the Wall Between Lending and Liquidity

Kash Dhanda, Jupiter's chief operating officer, framed the launch as closing a long-standing gap in on-chain finance. "There's been a wall between the two primary ways people earn APY on-chain, lending and LPing," he said, referring to lending and supplying liquidity to exchanges.

Dhanda said the design enables Jupiter to offer higher deposit rates and cheaper borrowing, with terms improving as the vaults attract more trading volume.

"It is not about just serving existing loans, but providing efficiency to grow the entire market," he said. Jupiter expects a mix of new loans and migrated positions from existing users but has not disclosed a specific target or cap.
