Jupiter, the leading decentralized exchange aggregator on Solana, has launched Ultra V3, which the team describes as the most advanced end-to-end trading engine ever created. This upgrade, released in October 2025, focuses on three core improvements traders value most: price, execution, and protection.
Ultra V3 introduces Meta Aggregation technology powered by Iris, a new routing system that scans multiple liquidity sources—including JupiterZ, DFlow, Hashflow, and OKX—to ensure users always receive the best available prices. For execution, it features ShadowLane, a private transaction landing system combined with Predictive Execution, optimizing for privacy and precision while reducing slippage. The protocol also boasts 34x stronger sandwich protection and advanced slippage estimation tools to prevent frontrunning and transaction manipulation.
Measurable results from the upgrade include +0.6 bps positive slippage versus competitors' averages of -1 to -14 bps, and 8–10x lower execution fees. Ultra V3 is fully integrated across mobile, web, desktop, API, and Pro Tools, requiring no user adjustments. Additional features include enhanced gasless support—allowing trading without holding SOL for fees—Ultra Signaling, JIT market revivals, and expanded accessibility for Token-2022 assets and memecoin pairs with a reduced minimum trade size of $10. JupiterZ, the in-house RFQ system processing about $100 million in daily volume with zero slippage, is now exclusively available through Ultra V3.
