Solana decentralized exchange aggregator Jupiter unveils Ultra v3 offering improved trade execution, MEV protections and 'gasless support'

Solana decentralized exchange aggregator Jupiter has unveiled the third version of its Ultra protocol, calling it “the most advanced end-to-end trading engine ever created.” 

According to Jupiter , Ultra v3 offers 34x better sandwich protection, “industry-leading performance” in terms of slippage, and up to 10-times lower execution fees.

The launch also unveiled a new router, called Iris, a so-called meta aggregator that finds the best pricing between trading platforms like JupiterZ, DFlow, Hashflow, and OKX. JupiterZ is a native Request for Quote (RFQ) system, which facilitates about $100 million in daily volume with zero slippage, according to Jupiter, that will be exclusively available via Ultra v3.

At launch, Ultra v3 is integrated across all of Jupiter’s products, including its mobile and desktop apps as well as its API and Pro Tools.

Powering the aggregator's improved metrics is Jupiter's upgraded “predictive execution” engine that “intelligently prioritizes routes” to avoid slippage and perform “just in-time simulations” to achieve tighter quotes. 

The release also includes Jupiter’s “in-house transaction landing engine,” ShadowLane, which offers sub-second and private transaction execution. Ultra v3 also features improved protection from Maximal Extractable Value (MEV) attacks . 

“Other providers increase your risk of being sandwiched by selling your order flow to third-party MEV searchers,” Jupiter writes. “Ultra v3 does the opposite – it minimizes your exposure to toxic MEV by ensuring your trades are never handed off to any external provider for on-chain execution.”

Finally, Ultra v3 extends Jupiter’s “Gasless Support” feature that enables users to place trades without having SOL in their wallets to pay for network fees. “So long as one token has a qualifying value during a trade, Ultra will compute the gas from your transaction, and pay for it with your swap,” Jupiter said, noting its extended support includes the Token-2022 and memecoin-memecoin pairs as well as a lowered $10 minimum trade size.
