Recently, on October 17, 2025, the leading decentralized exchange (DEX) aggregator on the Solana blockchain – Jupiter – announced the launch of the Ultra v3 protocol. This updated trading engine is described as "the most advanced end-to-end mechanism for trading ever created." Ultra v3 promises to radically enhance user experience by making trading faster, safer, and cheaper.
Key innovations include 34-fold protection against "sandwich attacks" – a common form of MEV exploitation where bots manipulate prices. The protocol also provides industry-leading slippage control and reduces execution fees by up to 10 times. The new router Iris, as a meta-aggregator, scans for the best prices on platforms JupiterZ, DFlow, Hashflow, and OKX, processing $100 million daily without slippage.
The predictive execution engine with "just-in-time" simulations optimizes routes in real-time, while ShadowLane – an internal tool – ensures private transactions in less than a second. A standout feature is "gasless" trading: now users can exchange assets without SOL in their wallet to pay for network fees.
Ultra v3 is integrated into all Jupiter products – mobile and desktop applications, API, and Pro Tools. This release strengthens Jupiter's position as a leader in Solana DeFi with a billion-dollar monthly volume, emphasizing transparency and security. Traders are already noting positive changes: lower risks, higher efficiency, and accessibility.
This upgrade is a step towards the mass adoption of DeFi on Solana, where speed and low costs become the norm. Stay tuned for developments!
