Jupiter Exchange has officially launched Ultra V3, its next-generation trading engine, a massive leap forward in performance, protection, and precision.
The upgrade introduces a complete suite of execution enhancements, Iris-based meta aggregation, ShadowLane transaction landing, predictive execution, and advanced slippage modeling, all designed to deliver one simple promise: the best possible price on every trade.
Ultra V3 also comes with gasless transactions, Ultra signaling, and on-demand market revival, setting a new benchmark for DeFi execution infrastructure.
What Ultra V3 Delivers
Ultra V3 is designed around three trader priorities:
- Best Price, via Iris, Jupiter’s new routing system.
- Best Execution, through ShadowLane and Predictive Execution.
- Best Protection, with advanced slippage modeling and sandwich-attack mitigation.
In numbers, the results speak for themselves:
- 34x better sandwich protection
- +0.6 bps positive slippage, compared to -1 to -14 bps on competing platforms (7-day vol-weighted study)
- 8–10x lower execution fees
This is performance that traders can see and measure on-chain.
Iris: The Core of Meta Aggregation
At the heart of Ultra V3 is Iris, Jupiter’s brand-new routing engine built exclusively for Ultra. It replaces Metis, delivering 100x routing performance improvements using advanced algorithms like Golden-section and Brent’s method.
Iris integrates with multiple aggregation systems, JupiterZ, DFlow, Hashflow, and OKX, to locate the absolute best execution path across Solana’s liquidity landscape.
JupiterZ, Jupiter’s internal RFQ system, alone facilitates around $100 million in daily volume with zero slippage, fully powered by Ultra V3.
The outcome: trades that always land at the most efficient, real on-chain price, not just the theoretical best quote.
Predictive Execution: Smarter Routing for Real Outcomes
Most DEXs show idealized quotes that vanish once your trade hits the chain. Ultra’s Predictive Execution fixes that.
Instead of relying on static simulations, it uses real-time modeling to anticipate slippage before execution, not after. It prioritizes stable, high-confidence routes, performing just-in-time simulations on every swap to ensure what you see is what you actually get.
This system also uses Ultra Signaling, an on-chain framework that helps Prop AMMs (proprietary market makers) detect non-toxic order flow. That allows them to quote up to 50% tighter spreads, passing better pricing directly to Ultra users.
Behind it all runs RTSE, Jupiter’s Real-Time Slippage Estimator, an engine refined over two years to deliver the most accurate execution conditions in DeFi.
ShadowLane: Precision Transaction Landing
Jupiter has also introduced ShadowLane, its in-house transaction landing system designed for sub-second accuracy.
- Private by design, no external relays or order-flow sales
- 3x more trades landed than alternative systems
- Latency reduced from 1–3 blocks to 0–1 block (50–400ms)
It’s powered by Jupiter’s new RPC engineering team, featuring contributors to major Solana infra like Yellowstone-gRPC, Lite-RPC, and Agave.
This isn’t just good for Jupiter, it benefits the entire Solana network, improving block propagation and transaction reliability ecosystem-wide.
34x Better MEV Protection
Ultra V3’s internal execution model gives users industry-best MEV protection, minimizing exposure to sandwich attacks by eliminating third-party order flow sales.
While on-chain risk can’t ever be completely removed (validators still broadcast blocks), Ultra’s design keeps it near zero.
In comparison, most premium trading terminals expose users to higher MEV risk through external relays or bundled transactions.
With Ultra, your trade stays private, direct, and secure, every time.

RTSE: Real-Time Slippage Estimator
Setting slippage has long been a guessing game for traders, especially on volatile tokens.
Ultra’s RTSE automates it with live data analysis, pulling from token volumes, volatility patterns, and trade frequency to set an optimal range.
Key upgrades in V3 include:
- Reduced default slippage while maintaining high success rates
- Auto-prioritization of slippage-protected routes
- Enhanced volatility sensitivity for unstable pairs
Whether you’re swapping SOL, stablecoins, or low-cap memes, Ultra ensures smooth execution without overspending.
Gasless Trading and Just-in-Time Market Revival
With Enhanced Gasless Support, users can now trade without holding SOL for gas. The system automatically computes fees and deducts them from the swap itself.
Gasless now supports Token-2022 pairs and meme-to-meme trades, with minimum trade sizes as low as $10.
Meanwhile, Ultra’s Just-in-Time Market Revival lets traders interact with forgotten or illiquid markets. No liquidity threshold, no exclusions, even old or inactive tokens can be routed, repriced, and traded again.
It’s complete Solana coverage, down to the last meme coin.
Seamless Integration Across Platforms
Ultra V3 powers every Jupiter surface:
- Web, Portfolio, Swap, Pro, Perps, Lend, and more
- Mobile, Fast, clean, and 10x cheaper
- Desktop Wallet, Deep integration, analytics, and gasless trading
Each interface syncs seamlessly, with unified analytics and PnL tracking, creating a single, consistent trading experience across devices.
For power users, Ultra integrates directly into Pro Tools, Terminal, Screener, Analytics, and Alphascan, giving professional traders deep visibility into market flows, token performance, and execution data.
Ultra V3 replaces Jupiter’s legacy Metis router, which is now sunsetted.
Developers still using the old Jupiter Legacy API are encouraged to migrate to Ultra API for accurate pricing and fair user representation.
As Jupiter noted, some external platforms still use deprecated binaries and falsely label them as “best price from Jupiter”, a misleading practice the team aims to eliminate.
Ultra V3, Built for Everyone
No setup. No adjustments. No hidden cost.
Just faster, smarter, safer trades, out of the box.
Ultra V3 represents everything Jupiter stands for: accessibility, protection, and real performance. Whether on mobile, desktop, or API, the experience is consistent, reliable, and built with precision.
As Jupiter’s team summed it up:
“Ultra V3 is built for YOU. Zero config. Lowest fees. Best protection. Seamless across all devices.”
With this release, Jupiter cements itself as Solana’s most advanced liquidity and execution layer, built by traders, for traders.
