Cetus CLMM

Cetus CLMM is not on the current firm shelf because its structure falls within the amm-lp policy class. This is a firm policy decision. It is not a negative quality rating or a client trade instruction. The facts about its mechanism, control, loss, and exit follow.

Review triggers: events that reopen the verdict
• Ships an economically separate product without pooled multi-asset inventory or relative-price rebalancing that merits its own review

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-15.

The research file

Mechanism applicability

Cetus documentation describes a concentrated-liquidity market maker. An LP selects a pair and price range, receives a position NFT, and earns swap fees only while the market price is in range. Cetus defines a range order as single-sided assets that are continuously swapped into the other asset as spot price crosses the position. It also warns that narrow ranges have higher impermanent-loss exposure. These facts place Cetus in the AMM-LP class.

Current observation and control applicability

The DefiLlama API read on 2026-08-15 reported approximately $29.4M of Cetus DEX liquidity, chiefly on Sui with a small Aptos balance. It also reported a separately labelled $4.7M staking balance outside this LP perimeter. Cetus describes the Sui CLMM as autonomous contracts that users operate through calls. Pool creators select pairs, initial price, range, and fee tier. We have not reviewed current pool composition, contract versions, upgrade controls, or incentives because the AMM mechanism already decides.

Exit and incident applicability

Closing a Cetus position realizes its current two-token inventory. A range crossed completely can leave the LP effectively in one asset, and an out-of-range position stops earning fees. Cetus disclosed a May 22, 2025 CLMM exploit caused by an overflow-check flaw. It globally disabled relevant contracts, patched the vulnerable contract, and pursued recovery. The incident adds material weight to contract and control review, but the shared AMM-LP decision does not depend on it.

Why the class rule decides

The shared v1 AMM-LP dossier decides because Cetus fees must overcome divergence loss created by pooled inventory and price-range execution. Reopen the file only if Cetus ships an economically separate product without pooled multi-asset inventory or relative-price rebalancing. That product would need its own review of chains, contracts and upgrades, audits and post-incident remediation, assets, controls, fees, liquidity, and stressed exits. Higher TVL or a new range shape alone would not change this verdict.

Class rule

The amm lp class is outside the approved structures, so every protocol in it is not approved until the rule changes. The rule is about the structure, not an adverse finding about this protocol, and it is not a client instruction. The events that would reopen it are listed with the memo.

The claims above trace to these. Where a number could not be independently verified, the thesis says so.

Inherited controls

The research above describes the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The layer with the most administrative power sets the position’s effective control; that describes control, not quality or suitability.
