Jupiter, a leading decentralized exchange on the Solana blockchain, has launched a new trading engine designed to significantly enhance security, reduce transaction costs, and broaden accessibility for users in the competitive decentralized finance (DeFi) sector.
The “Ultra v3” protocol offers 34 times greater protection against “sandwich attacks,” a common form of market manipulation where third parties profit by front-running and back-running user transactions. Jupiter aims to mitigate this risk through a private, internal execution architecture.
The update also promises up to 10 times lower execution fees and “industry-leading” performance in managing price slippage.
A key feature of Ultra v3 is “Gasless Support,” which allows trades without requiring Solana’s native SOL token to cover network fees. The system automatically calculates and pays gas costs using one of the swapped tokens.
This gasless functionality has been extended to Token-2022 and memecoin-memecoin pairs. Furthermore, the minimum trade amount has been lowered to $10, aiming to attract a wider range of retail investors and memecoin enthusiasts.
Jupiter describes Ultra v3 as “the most advanced trading engine ever created” on Solana. It integrates “Iris,” a new meta-aggregator that finds optimal prices across various platforms, including JupiterZ, DFlow, Hashflow, and OKX.
JupiterZ, the exchange’s native Request for Quote (RFQ) system, processes approximately $100 million in daily volume without slippage and is now exclusively accessible via Ultra v3.
The engine incorporates “predictive execution” capabilities for real-time route prioritization and instant simulations, designed to provide more precise quotes and further reduce slippage.
A new internal transaction landing engine, “ShadowLane,” facilitates private, sub-second transaction executions to improve resistance against Maximal Extractable Value (MEV) attacks. Jupiter emphasized that Ultra v3 avoids selling order flow to third parties, a practice it claims increases user risk.
The new protocol is fully integrated across Jupiter’s mobile application, desktop version, API, and professional developer tools. These advancements are intended to solidify Jupiter’s position within Solana’s DeFi ecosystem amid increasing competition focused on speed, privacy, and multi-chain liquidity.
