Cetus

Cetus bet early on the Move programming language and won: as Sui's mainnet launched in 2023, Cetus was there as its primary liquidity layer, and it has since grown into the dominant DEX across both Sui and Aptos. Its concentrated liquidity market maker (CLMM) design lets LPs allocate capital in custom ranges, maximizing fee efficiency in the style of Uniswap v3.

The protocol positions itself as infrastructure rather than just an exchange: its aggregator routes trades across Sui venues, its SDKs power swaps inside wallets and apps, and its permissionless pool creation makes it the default listing venue for new Sui tokens. As Sui's DeFi TVL climbed the chain rankings, Cetus captured that growth directly.

CETUS, the utility token, pairs with xCETUS for loyalty staking and launchpad access. Cetus is the essential venue for anyone trading on Sui, offering the chain's deepest liquidity and best tooling; users should note that Sui DeFi is young, and in 2025 Cetus weathered and recovered from a major exploit — a reminder that Move-ecosystem protocols carry early-stage risk.
