Lend v2 goes live
Solana lending giant Jupiter launched Lend v2, a product that lets deposits and borrowed positions act as trading liquidity so the same capital can earn both lending interest and a share of swap fees.
“Jupiter Lend holds about $1.9 billion in deposits”
The update ties higher returns to whether Jupiter’s router can send enough swap flow through the new vaults, with the extra yield existing only if traders actually swap through those pools.
CoinDesk said Jupiter Lend holds about $1.9 billion in deposits and generated $1.6 million in fees over the past 30 days, while active loans stand at $822.7 million and have fluctuated between $600 million and $900 million since September.
The design is built around two optional features, Smart Collateral and Smart Debt, which automatically pair assets into correlated liquidity pools and are intended to improve capital efficiency without requiring users to manage separate strategies.
How it earns, and risks
Smart Collateral pairs deposits of USDC, USDT, SOL or JupSOL into correlated liquidity pools so the assets can earn yield on loans while gaining trading fees and, where applicable, staking rewards from one position.
Smart Debt applies the same concept to borrowed assets, so fees generated by a debt position offset the cost of the loan when traders route swaps through those pools.
CoinDesk described a key asymmetry: on the debt side the borrower is protected if a stablecoin depegs, but on the collateral side there is no such protection and a supplier carries the loss on both assets if either breaks.
KuCoin framed the core risk as overlapping exposures, where depositors face standard lending risk plus market-making risk tied to the router’s ability to process profitable swap flow, and a thin-volume week can cut into the advertised APY on lend positions.
What to watch next
Jupiter said its router does not favor its own vaults and sends swaps wherever the price is best, while the product confines the structure to correlated pairs such as stablecoins against each other and SOL versus its staked versions.
“The next 30 days of active loans will show whether yield was the thing holding it back”
CoinDesk reported that Jupiter expects a mix of new loans and migrated positions, without giving a target or a cap, and said the next 30 days of active loans will show whether yield was the thing holding it back.
KuCoin warned that the dependence on router volume is a vulnerability, because if Jupiter’s share of Solana swap flow declines or on-chain trading falls, the yield boost can evaporate and the justification for the extra risk weakens.
In the same framing, KuCoin said the system becomes self-reinforcing only if the market believes it will work, making stress periods—when both lending demand and swap volume can collapse—an essential test of the model’s correlations.
