Jupiter Ultra Cuts Solana Sandwich Attack Exposure
A three-year study by researchers from Category Labs, ETH Zurich, Flashbots and the University of Lisbon found 28 million sandwich attacks on Solana across six blockchains. Jupiter Ultra users faced substantially lower exposure than users of other Solana trading terminals.
The study measured attacks using an excess ratio. Jupiter Ultra recorded 0.7 overall and 2.0 in single-victim cases, compared with 18.9 for Axiom, 11.1 for Photon and more than 10 for BullX and GMGN. Jupiter Ultra’s lower attack rate is linked to private routing, dynamic slippage estimation, Iris meta-aggregation and Ultra Signaling, introduced with Ultra V3 in October 2025.
Jupiter claims 34-times stronger sandwich protection, average positive slippage of 0.6 basis points and fees 8–10 times lower than competing platforms. However, the researchers said Jupiter Ultra does not eliminate the risk because validators remain a potential attack vector.
The findings suggest that application-level order routing and transaction privacy can materially affect trading execution and MEV exposure, even on the same blockchain. For traders, Jupiter Ultra may reduce execution losses, but protection should not be treated as complete. The study is a risk-management development rather than a direct price catalyst for SOL or JUP.
Neutral
The market impact is neutral because the study concerns trading infrastructure and execution quality rather than network demand, token economics or capital flows. In the short term, the findings could benefit Jupiter’s reputation and increase usage of its Ultra routing, potentially supporting JUP sentiment. They may also encourage Solana traders to move from publicly exposed terminals to private or protected order flow.
However, the report does not remove the broader risk of MEV on Solana. The finding of 28 million sandwich attacks could reinforce concerns about execution quality and deter some users, while competitors may respond with similar protection. Any effect on SOL is likely to be limited because the study does not indicate a change in Solana’s fees, throughput or liquidity.
Over the long term, wider adoption of private routing, dynamic slippage controls and MEV-aware execution could improve DeFi market stability and reduce persistent trading losses. Similar developments in Ethereum’s private transaction and order-flow markets have generally improved execution for protected users without creating an immediate broad-based token rally. Traders should therefore treat the news as a platform-level risk-management signal, while monitoring Jupiter volumes, JUP performance, Solana DEX activity and evidence of continued sandwich attacks.
