Solana’s top decentralized exchange aggregator Jupiter has unveiled a new trading engine to improve its performance.
DeFi traders on Solana received a major upgrade. On Monday, Oct. 20, Solana’s liquidity aggregator Jupiter officially launched Ultra V3, a new trading engine. According to Jupiter, the engine makes transactions faster, cheaper, and more secure.
The system introduces three new technologies: Iris Router, ShadowLane, and Predictive Execution, to reduce fees and eliminate slippage surpluses. According to Jupiter, it is a major improvement not just for its platform, but also for the Solana (SOL) Network.
Jupiter also claims that the upgrade offers 34x better protection against sandwich attacks, a type of MEV attack where validators place transactions before and after those of regular users, increasing slippage and causing losses for traders.
According to Jupiter, Ultra V3 will also deliver 8x–10x lower execution fees compared with similar platforms. In addition, it aims to provide 0.6 basis points of positive slippage, meaning most traders will receive better prices than initially quoted.
The upgrade lowers barriers for retail users with expanded gasless support and reduces the minimum trade size to $10.
