jUSD is a synthetic dollar designed to generate yield without relying on directional market exposure. It is issued by Aegis and backed by JLP as collateral. jUSD derives its returns from trading activity across the Jupiter Perps platform while maintaining a delta-neutral risk profile. The core idea behind jUSD is to separate yield generation from market conditions. Instead of holding spot assets or taking speculative positions, the protocol earns revenue produced by trader activity on Jupiter and removes price risk through hedging via perpetuals. This allows jUSD to function as a stable, dollar pegged asset with built-in yield, even during periods of low funding rates or choppy markets.Why JLP?JLP is a liquidity provider token that represents an ownership share in a pool used to supply liquidity for trading on Jupiter Perps; it consists of SOL, ETH, BTC and USDC. JLP's yield accrual comes from several sources: trading fees paid by market participants, funding rate payments and liquidation proceeds generated when leveraged positions are forced-closed. JLP’s value fluctuates based on trader profitability and the price of underlying volatile assets. JLP captures meaningful fee revenue during periods of high market volatility and trading activity. This makes JLP an efficient yield-generating collateral base that largely consists of blue-chip assets. jUSD uses JLP as collateral because JLP generates yield from trading activity. Price exposure from the assets inside JLP is neutralized through derivative hedging so yield is earned while directional risk is removed.Tokenizing the StrategyThe central design objective of jUSD is to isolate the revenue component of JLP while removing directional risk. This is achieved by pairing long spot JLP exposure with short perpetual positions that mirror the JLP asset composition. As the composition of JLP changes over time due to trading activity, the system dynamically adjusts hedge sizing and proportions. The result is a delta-neutral position where gains and losses from price movements are offset, while revenue continues to accrue. jUSD differs from stablecoins collateralized by idle assets. By using JLP as collateral, it earns yield from trading activity on Jupiter Perps even during periods of low or negative funding rates.Asset Flow and System ArchitectureThe operational flow of jUSD utilizes Ethereum, Solana and the perpetual platforms used for hedging. Each step is designed to separate custody, hedge execution and yield distribution, while maintaining transparency. The asset flow is as follows:A whitelisted user deposits USDC into the jUSD minting contract on EthereumThe collateral manager transfers the USDC and bridges it to SolanaJLP is acquired on SolanaA portion of JLP is posted as collateral to borrow USDC while the rest of the JLP is transferred to a multisigBorrowed USDC is sent to Copper, mirrored on an exchange and used to open short perpetual positions aligned with JLP compositionHedge positions are continuously monitored and resized as JLP composition changesThe revenue earned is used to mint new jUSD, which is deposited into the staking contract, increasing the value of sjUSDUpon redemption, JLP is sold, USDC is bridged back and part of the hedging position is closedThroughout this process, the protocol tracks balances, exposures and liabilities in real time. The goal is to maintain consistent delta-neutrality while capturing sustainable yield.Risk ControlsjUSD’s design prioritizes transparency and predictability over aggressive yield optimization. Borrowing against JLP is capped and hedge positions are continuously adjusted to keep exposure aligned with the underlying collateral. The protocol does not rehypothecate collateral and borrowed assets remain within trusted custodians. Risk management focuses on several components:Hedge accuracy: ensuring that exposure to prices of BTC, ETH and SOL remains close to zero, while mirroring JLP's compositionLeverage constraints: closely monitoring hedge position margin, along with maintaining conservative LTV ratios for borrowed USDCLiquidity management: ensuring redemptions can be met without impacting the underlying strategyOperational isolation: separating custody, execution and yield to reduce contagion during potential failuresLosses from negative funding or market volatility are absorbed by the Aegis insurance fund, before affecting users, and yield distribution is adjusted dynamically to reflect realized gains.sjUSD and Yield DistributionsjUSD represents the yield-bearing version of jUSD. The protocol increases the backing of sjUSD by depositing the earned revenue as minted jUSD, which increases its value. This design allows yield to compound automatically without requiring user interaction. Users can stake jUSD for sjUSD to earn yield, or unstake sjUSD back into jUSD to realize the yield earned. The yield is earned from JLP revenue and funding rates on the hedge position (if positive).Design PhilosophyjUSD is built around the idea that sustainable onchain yield should come from real activity within the market, which is verifiable in real time. By anchoring its design to trading revenue and enforcing strict risk controls, the system aims to deliver a stable, transparent yield source that remains viable across various market conditions. The design emphasizes controlled execution and clearly defined operating boundaries on every aspect of the protocol. Capital movement follows predetermined paths, with specific limits governing how collateral is deployed, how exposure is adjusted and how positions are maintained over time. These limits are enforced through rigorous backtesting that removes unexpected behavior and reduces the chance of asset price exposure as market conditions change. Choose Aegis, because your money deserves better.
