Jupiter has introduced Ultra V3, its next-generation trading engine built to improve execution across Solana’s DeFi markets.
The update brings advanced meta aggregation, predictive execution, and enhanced protection from sandwich attacks. It also introduces the Iris router, a new technology that optimizes price routing between multiple liquidity sources.
The launch signals Jupiter’s move toward faster, safer, and more transparent trades.
The centerpiece of Ultra V3 is the Iris router, which replaces Jupiter’s retired Metis system. According to Jupiter Exchange, Iris combines data from multiple routers including JupiterZ, DFlow, Hashflow, and OKX to secure the best on-chain prices.
The new algorithm uses mathematical techniques like Golden-section and Brent’s methods, achieving up to 100x better routing performance.
JupiterZ, an in-house RFQ system handling around $100 million in daily volume, integrates exclusively with Ultra V3. Together, they enable more accurate trade execution and minimal slippage, reducing the gap between quoted and executed prices.
Predictive Execution further refines this by prioritizing optimal trade routes and simulating real-time outcomes before confirmation.
This system avoids misleading quote inflation that often affects decentralized exchanges. Instead, it ensures users receive the actual market execution price. Jupiter stated that this model leads to consistent positive slippage, outperforming competitors that show negative averages.
Another core feature, ShadowLane, is Jupiter’s internal transaction landing engine designed for speed and precision.
It executes trades privately without relying on external relays or third-party order flow handlers. The result is a threefold increase in successful trade landings and latency reduced to as little as 50 milliseconds.
The upgrade also strengthens protection from miner extractable value (MEV) exploits.
Ultra V3 minimizes risks by keeping all order execution internal, providing 34 times better sandwich protection compared to competing terminals. The new Real-Time Slippage Estimator, or RTSE, adjusts slippage settings dynamically, ensuring smooth transactions across volatile markets.
In addition, the update expands gasless trading. Users can now complete swaps without holding SOL, as Jupiter automatically deducts gas fees from trade value. The enhancement supports Token-2022 assets and smaller trade sizes, making DeFi access easier for smaller wallets.
Ultra V3 integrates across Jupiter’s web, mobile, desktop, and API platforms. It also powers Jupiter Pro tools like Terminal, Screener, and Analytics for professional traders. This ensures a consistent trading experience across devices and deeper data visibility into every trade.
By blending execution precision, on-chain safety, and user accessibility, Jupiter aims to raise the bar for Solana-based DeFi infrastructure. Ultra V3 is already live across its entire product suite, available to both retail and institutional users.
