TL;DR
- Solana’s DEX, Jupiter, launched Ultra v3, improving order execution, slippage, and protection against MEV attacks.
- Ultra v3 includes Iris, a meta‑aggregator that finds the best quotes across platforms like DFlow, Hashflow, and OKX.
- The Gasless Support feature allows users to trade without SOL in their wallet, calculating transaction gas from the swap.
The Solana decentralized aggregator, Jupiter, unveiled Ultra v3, the third version of its Ultra protocol, transforming trading on the network.
Jupiter Introduces Disruptive Changes
The update promises to significantly improve order execution, reduce slippage, and provide advanced protection against Maximal Extractable Value (MEV) attacks. Additionally, it enhances compatibility with its “gasless” trading feature.
Ultra v3 increases sandwich attack protection by up to 34 times and delivers industry-leading performance in terms of slippage. It also reduces execution fees by up to ten times compared to previous versions.
The update introduces a new router called Iris, a meta-aggregator that scans multiple platforms such as JupiterZ, DFlow, Hashflow, and OKX to find the best possible quotes. JupiterZ, a native Request for Quote (RFQ) system, handles around $100 million in daily volume with zero slippage and will be exclusively available through Ultra v3.
Ultra v3 Ensures Trade Integrity and Security
Jupiter’s predictive execution engine powers these improvements, intelligently prioritizing routes and performing “just-in-time” simulations to ensure tighter quotes. The platform also incorporates ShadowLane, an in-house engine that executes private transactions in under a second and prevents orders from being sent to external providers, minimizing exposure to MEV attacks.
Jupiter emphasizes that, unlike other services that sell order flow to MEV searchers, Ultra v3 protects users from external risks, ensuring the integrity of every trade.
Ultra v3 also extends the Gasless Support feature, allowing users to execute trades without holding SOL in their wallets to pay network fees. As long as a token has value during the swap, Ultra calculates the transaction gas and deducts it from the swap, expanding coverage to Token-2022 and memecoin-memecoin pairs and lowering the minimum trade size to $10.
The update integrates seamlessly across all Jupiter platforms, including mobile and desktop apps as well as its API and professional tools. With Ultra v3, the protocol becomes one of Solana’s most advanced aggregators, offering traders and investors greater efficiency, security, and flexibility in order execution
