The Jupiter decentralized exchange aggregator, built on Solana, has launched the third version of its Ultra protocol. The team has described it as “the most advanced end-to-end trading engine ever created.”

According to the announcement, Ultra v3 offers:

• 34 times more effective protection against sandwich attacks;
• “industry-leading performance” in terms of price slippage;
• execution fees reduced by up to 10 times.

The release also includes a new router, Iris. It enables Ultra to find the best prices through so-called meta-aggregation across platforms like JupiterZ, DFlow, Hashflow, and OKX.

JupiterZ is a native request-for-quote system. According to the developers, the solution facilitates a daily trading volume of around $100 million with zero slippage and is exclusively available through Ultra v3.

The upgrade includes the implementation of the “internal transaction processing mechanism” ShadowLane, which ensures confidential and precise operations in less than a second.

The updated protocol also offers enhanced protection against MEV activity. Developers claim that other providers expose users to sandwich attack risks by “selling order flow” to third-party searchers.

“Ultra v3 does the opposite — it minimizes the impact of toxic MEV on you, ensuring that trades are never handed off to an external provider for online execution,” the statement reads.

The solution does not eliminate such risks entirely but comes close, the Jupiter team emphasized.

Additionally, the third version of the engine expands the Gasless Support feature, allowing transactions without SOL in the wallet to cover network fees. The protocol calculates the gas cost for the transaction and includes it in the swap.

The update increases the number of supported token types and reduces the minimum trade limit to $10.

According to DeFi Llama, Jupiter leads the DEX aggregator segment with a trading volume of approximately $23.6 billion over the past 30 days.

With a daily figure of $2.2 billion at the time of writing, the platform has surpassed the combined volume of the other top five platforms.

Earlier in October, the Jupiter team announced a partnership with Ethena Labs to launch the native stablecoin JupUSD on Solana.
