Question 1

What is the best Sui DEX for beginners?

Accepted Answer

For straightforward spot trading, Cetus and Aftermath Finance are good starting points thanks to broad token support and clean interfaces. If you're interested in perpetuals or more active trading, Bluefin is a good choice on Sui.

Question 2

How does a DEX on the Sui network work?

Accepted Answer

DEX services work by using liquidity pools, where users contribute their own tokens to earn rewards when others trade against those pools. This is different from CEXs and other centralized services, where all liquidity is provided and controlled by the operator. DeepBook is a partial exception – it uses a central limit order book model rather than AMM pools.

Question 3

Which is the biggest DEX on Sui?

Accepted Answer

By perpetuals volume and overall trading activity, Bluefin is one of the dominant DEXs on Sui in 2026. Cetus is leading spot DEX volume. By TVL and ecosystem footprint, Bluefin, Cetus, and Momentum are among the largest Sui DeFi protocols. Check DefiLlama for the latest numbers and rankings.

Question 4

Is Cetus safe to use after the 2025 exploit?

Accepted Answer

Cetus relaunched in June 2025 after restoring most pool liquidity through treasury funds and a Sui Foundation loan, and has shipped post-incident security work. It's operational and widely used again. As with any DeFi protocol, evaluate your own risk tolerance and don't deposit more than you're prepared to lose.
