The Sui blockchain ecosystem’s decentralized exchange (DEX) trading volume reached a historic high of $3.649 billion for the week of April 20-26, according to data from DeFiLlama. This milestone coincides with Sui’s impressive 74.70% price increase over the same period.
Cetus accounted for 42.8% of all DEX trading activity on the network. The leading Sui-based exchange processed $1.694 billion in weekly trading volume, with its daily volume reaching $182.82 million.
Momentum has surpassed Bluefin to claim the second position among Sui-based exchanges. Momentum achieved a milestone on April 27 when its single-day trading volume peaked at $91.59 million. The platform’s weekly volume reached $479.29 million, which is approximately 13.1% of all Sui DEX activity. This performance is a 165% increase over the previous week.

Bluefin, now in third position, has nonetheless posted impressive numbers with $531.58 million in weekly volume and a 153% week-over-week increase. The exchange currently maintains $72.2 million in TVL.
SUI’s impressive performance over the past week
Sui has registered the sixth-largest weekly percentage gain of any major blockchain network, with a 74.70% increase, leaving it only in second place behind Base’s staggering 416% weekly increase. However, Sui’s daily trading volume of $427.1 million is much smaller than much larger networks, including Solana ($2.451 billion) and Ethereum ($1.123 billion).
Sui’s DEX TVL is currently $421.66 million, much, much smaller than industry leaders, but increasing rapidly. With a total weekly volume of $3.649 billion, the network can reasonably compete against more established blockchains like BSC (recording $8.291 billion in weekly volume, for instance).
Not every project in the Sui ecosystem has benefited from the upward movement, however. Kriya saw a 46.81% drop for the week and only saw $492.65 million in volume for the week despite most of the market going up.
DeepBook rounds out the five Sui DEXs with $130.4 million in weekly volume and a 136% increase in volume. Although it only has $30.07 million in TVL, it is a small but still crucial piece of the Sui DeFi ecosystem.
