Jupiter has released Ultra v3, the latest upgrade to its Solana-based trading engine. We promise 34x stronger sandwich protection, 10x lower execution fees, and industry-leading slippage performance, all integrated into Jupiter’s apps, APIs, and Pro Tools. Ultra v3 brings Solana DeFi to a new level of speed, safety, and efficiency with predictive execution, private transactions, and gasless trading.
What makes Ultra v3 a big step forward?
Jupiter, a decentralized exchange aggregator representing Solana, introduced Ultra v3 is being called the most advanced end-to-end trading engine ever built. The new version provides 34x stronger sandwich protection, industry-leading slippage performance, and up to 10x lower execution fees, setting a new standard in decentralized trading efficiency.
Integration across all Jupiter platforms
Ultra v3 at launch was Fully integrated into the entire Jupiter ecosystem– Includes mobile app, desktop interface, API, and Pro Tools. This allows users on any platform to experience consistent performance improvements, faster trading, and enhanced protection from slippage and front-running.
Introducing Iris Meta Router
The highlight of this release is Iris, Jupiter’s new meta-aggregator router. Iris identifies the best trade route by comparing liquidity and prices across multiple platforms including JupiterZ, DFlow, Hashflow, and OKX.
Notably, JupiterZ, the native Request for Quote (RFQ) system that processes nearly $100 million in trade volume daily, is now exclusive to Ultra v3, offering zero slippage execution and more predictable trading results.
Predictive execution and the ShadowLane engine
Ultra v3 runs on an improved predictive execution engine that uses real-time simulation to prioritize the best routes and deliver tighter estimates. The system predicts potential slippage and dynamically adjusts order flow before execution.
Powering this is ShadowLane, Jupiter’s proprietary in-house transaction landing engine, which enables private execution in sub-seconds. This dramatically increases both speed and privacy, reducing exposure to blockchain congestion and opportunistic MEV attacks.
Enhanced MEV protection
Maximal Extractable Value (MEV) attacks are a persistent threat across decentralized exchanges, often leading to “sandwich” exploits. Jupiter’s Ultra v3 is designed to neutralize this risk.
Unlike competitors that sell order flow to MEV searchers, Jupiter ensures that trades never leave the controlled execution environment. This closed-loop design prevents front-running and ensures that users’ transactions remain private and secure during execution.
Expanding gasless transactions and support
Ultra v3 enhances Jupiter’s gasless support capabilities, allowing users to trade without holding SOL for network fees. As long as the token being traded meets the qualifying value criteria, Ultra will automatically calculate the gas and deduct it from the trade itself.
This feature is now extended to Token 2022 assets, Memecoin vs. Memecoin pairs, and the minimum trade size is lowered to $10, widening accessibility for individual traders and small portfolios.
Jupiter’s ultra v3 This represents a significant advancement in DEX aggregation on Solana. The combination of predictive intelligence, zero-slippage routing, private execution, and MEV-tolerant architecture redefines what users can expect from a decentralized trading platform.
With Iris, ShadowLane, and Gasless features working together, Ultra v3 not only improves trade execution, but also rebuilds the foundation of trust, performance, and privacy in DeFi trading.
