Mike Hale Jupiter has launched Lend v2, a Solana lending upgrade that lets deposits and borrowed assets earn DEX trading fees on top of their existing yield. The new features, called Smart Collateral and Smart Debt, route lending positions into correlated liquidity pools so the same dollar earns from lending interest, trading fees, and in some cases staking rewards at once.
Jupiter Lend already holds $1.9 billion in deposits and has carried between $600 million and $900 million in active loans since September, with $822.7 million outstanding currently. Over the past 30 days the protocol generated $1.6 million in fees, an annualized yield of roughly 1% before the protocol split.
Lend v2 is built to push that number higher by putting idle collateral to work as active liquidity instead of letting it sit as a static backstop.
What are Smart Collateral and Smart Debt?
Smart Collateral and Smart Debt are optional Jupiter Lend v2 features that turn deposits and loans into active DEX liquidity, so the same position earns trading fees on top of its usual lending yield.
Smart Collateral takes a deposit of USDC, USDT, SOL, or JupSOL and automatically pairs it into a correlated liquidity pool. A depositor collects lending interest from Jupiter's unified liquidity layer, a share of trading fees generated as traders swap through that pool, and staking rewards where the asset supports them, all from a single position.
Smart Debt applies the same mechanic to the other side of the ledger. Borrowed assets get deployed as DEX liquidity too, and the trading fees they generate offset part of the borrowing cost, while borrowing and repaying still work the way they always have.
Both features are optional. A user who wants a plain lending or borrowing position can skip Smart Collateral and Smart Debt entirely and use Lend v2 the way they'd use any standard money market.
Why Jupiter limited this to correlated assets
Turning a lending position into liquidity introduces a risk that plain lending doesn't have: impermanent loss if one side of the pool depegs. Jupiter's design handles that risk asymmetrically. Borrowers using Smart Debt are protected. If a depeg happens, their position rebalances into the stable asset and they still owe the same amount they originally borrowed. Collateral providers carry more exposure. If either asset in the pool depegs, they absorb losses on both sides of the position.
To keep that exposure manageable, Jupiter restricted Smart Collateral and Smart Debt to correlated pairs only, stablecoin-to-stablecoin pools and SOL paired against its liquid staking derivatives like JupSOL. That rules out the wilder pool combinations where a depeg could wipe out a position fast, and it's the reason the feature launched with a short list of supported assets instead of an open market.
Fluid's liquidity layer
Lend v2 is built on the same architecture as Fluid, the protocol formerly known as Instadapp before its late-2024 rebrand. Fluid runs a unified Liquidity Layer that powers lending, vaults, and a DEX from one shared pool of capital instead of three siloed products. That shared-liquidity design is what makes Smart Collateral and Smart Debt possible. A deposit doesn't have to move between a lending market and a separate AMM to do both jobs. It sits in one pool that both markets draw from.
Jupiter runs Solana's largest swap router, the tool most wallets use to find the best execution price for a trade. With Lend v2, Jupiter now also owns liquidity pools that earn fees from that same swap flow.
Getting started with Lend v2
Smart Collateral and Smart Debt are live now at jup.ag/lend. If you're already lending or borrowing on Jupiter, upgrading a position means opting into the smart version of your existing asset rather than migrating to a new product.
Depositing: supply USDC, USDT, SOL, or JupSOL and opt into Smart Collateral to start earning lending yield, trading fees, and staking rewards from one position.
Borrowing: take a loan against supported collateral and opt into Smart Debt so the trading fees your borrowed asset generates chip away at your borrow cost.
Staying simple: skip both features and use Lend v2 as a standard money market if you'd rather not take on LP-style exposure.
Jupiter is betting that most of its $1.9 billion in deposits will move into Smart Collateral once users see the extra yield. How much of that actually happens over the next few months will show whether bundling lending and LPing works as well in practice as it does on paper.
