Jupiter, the leading liquidity aggregator on the Solana network, has launched Ultra V3, a comprehensive trading engine designed to deliver superior execution, enhanced security, and lower fees. The new engine is powered by three exclusive technologies: the Iris router, ShadowLane transaction landing, and Predictive Execution.

The platform reports that these architectural upgrades provide significant benefits, including a 34-fold increase in protection against sandwich attacks compared to other top trading terminals. Users also benefit from an average positive slippage of 0.6 basis points and execution fees that are eight to ten times lower than those on comparable platforms.

Siong, the co-founder of Jupiter, explained that unlike platforms that display optimistic quotes, Ultra V3 provides accuracy. “Ultra V3’s Predictive Execution gives you what you actually get at execution, not what looked good at quotation,” he stated. “Every swap lands exactly as promised—executed in the best way possible, at the best price, every time.”

The Technology Powering Ultra V3

At the core of the new engine is the Iris Router, which enables highly precise trade splits and uses sophisticated algorithms to find the most competitive prices. It works alongside JupiterZ, a proprietary Request for Quote (RFQ) system that facilitates approximately $100 million in daily zero-slippage volume.

Ultra V3 also introduces ShadowLane, an entirely new, in-house transaction landing engine built for speed and privacy. By avoiding external relays and order-flow sales, ShadowLane successfully lands three times more trades than alternative premium methods. Another key innovation is Predictive Execution, which performs just-in-time simulations for every route to accurately predict potential slippage and prioritize the optimal path for a trade.

A New Standard in MEV Protection

A major focus of Ultra V3 is minimizing exposure to toxic Maximal Extractable Value (MEV). While some providers increase sandwich attack risk by selling order flow to third-party searchers, Jupiter’s new engine keeps the entire process in-house. By never handing off trades to external parties for on-chain execution, the system reduces MEV risk to the lowest technically possible level.

Expanded Features for Modern Traders

The update brings numerous improvements for traders. Gasless support has been expanded to include Token-2022 and memecoin-to-memecoin pairs, with minimum trade sizes as low as $10. This allows anyone holding any asset to trade without needing SOL for gas fees. Additionally, a “Just-In-Time Market Revival” feature can route trades for any token on Solana, even those in inactive markets, by dynamically re-indexing liquidity on demand.

Ultra V3 is also deeply integrated with Jupiter’s professional trading suite, including its Terminal, Screener, and Alphascan tools, providing a seamless experience across its web, mobile, and desktop wallet interfaces.

Empowering Developers with the Ultra API

Developers can now access the same powerful infrastructure through the new Ultra API. Jupiter manages all the Remote Procedure Call (RPC) complexity and infrastructure maintenance, allowing developers to focus on building their applications while leveraging Jupiter’s execution capabilities.

The Path Forward

With the launch of Ultra V3, Jupiter will focus its development efforts on the new engine and the Iris router. The company is rolling out the Ultra API to its partners, many of whom will transition from the sunsetted Jupiter Legacy API (Metis). Jupiter has requested that platforms still using the legacy API correctly label their integration to avoid misleading users about their pricing sources.
