OpenOcean emerges as the top among March’s leading DEXs by volume
Topping the list of prominent decentralized exchanges (DEXs) by volume in March 2026, from the 1st to the 15th of the month, is OpenOcean. In particular, growing user confidence has reportedly played a crucial role in this significant spike in volume. To this end, OpenOcean has consistently delivered optimal pricing and seamless execution. In addition, the exclusive and innovative integrations enable the platform to maintain its user base and attract a wide range of people in the highly competitive market.
Paraswap and Nordstren take 2nd and 3rd place
According to DZap, Paraswap is another name on the list of leading DEXs. That’s why Paraswap became the second largest decentralized exchange by volume between March 1 and 15. Further on, third place is occupied by Nordstren, another DEX with notable volume. The respective rankings suggest that the increasing growth of these locations indicates that users are not focusing on the brand name but are prioritizing the benefits it offers.
