Jupiter Launches Ultra v3 Trading Engine with Enhanced Features

Solana-based DEX aggregator Jupiter has launched Ultra v3, a revamped trading engine with significant technical enhancements, on October 17–18, 2025, in an effort to improve DeFi liquidity.

This upgrade enhances trading efficiency, boosts MEV protection, and lowers fees, potentially impacting Solana’s trading landscape and benefiting high-liquidity assets like SOL and USDC.

Jupiter Ultra v3: 34x Boost in MEV Protection

Jupiter, a leading Solana-based DEX aggregator, has introduced Ultra v3, aiming to revolutionize trading with substantial improvements, including a 34x increase in MEV protection. Iris, their new router, leverages meta-aggregation across major exchanges for optimal pricing.

The integration of Ultra v3 across all Jupiter applications—from mobile and desktop to APIs—marks a notable shift in trading architecture. This enhancement promises a reduction in execution fees by 8-10x, which may broaden trading participation.

Upon launch, Jupiter received a positive reception, with community feedback highlighting the advantages of reduced fees and faster transactions. The official Twitter announcement emphasized the groundbreaking nature of the engine and its potential to reshape DeFi trading landscapes.

Solana’s Trading Dynamics Enhanced by Ultra v3

Did you know? The integration of Ultra v3 mirrors the impactful Uniswap v3 release, which significantly increased TVL and trading volume during volatile market phases.

Solana, symbol SOL, recently traded at $185.95, boasting a market cap of $101.70 billion. Marking a modest 1.40% price rise over 24 hours, the token saw a daily trading volume of $4.62 billion, according to CoinMarketCap.

Coincu research indicates that Ultra v3’s improvements could enhance liquidity depth, reducing slippage during high-volume trades. The enhancements in MEV protection and fee reduction further position Jupiter as a crucial player in DeFi advancements. These features may significantly alter trading behavior and boost Solana’s network efficiency.

With Ultra v3, we believe we have set a new standard for decentralized trading engines in the DeFi space. — Jupiter Team, Engineering and Leadership Group, Jupiter Exchange.
