Bluefin Spot
Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.
Bluefin Spot is the spot trading venue of the Bluefin exchange on Sui, and its depositors are liquidity providers in AMM pools. Any pool of assets that move against each other exposes the LP to impermanent loss: the pool sells the rising asset for the falling one, so the LP exits worth less than if they had simply held. That loss cannot be explained to this client in two sentences and is indefensible when it bites, so the AMM category is rejected regardless of protocol quality. Bluefin Spot held about $17M in TVL across 45 pools at the 2026-08-14 survey. Sui also has no resolved chain review, which would block the position on its own.

The research file
Mechanism applicability
Bluefin documents Spot as a concentrated-liquidity market maker on Sui. LPs deposit a token pair into a selected price range, swaps rebalance the position, and only in-range liquidity earns fees. That protocol-specific mechanism squarely applies the shared v1 AMM-LP dossier: concentration changes capital efficiency, not the paired-asset divergence exposure.
Current observation and perimeter
The DefiLlama protocol API read on 2026-08-15 reported approximately $17.7M of Bluefin Spot TVL, classified it as a DEX and identified Sui as the sole chain. Bluefin’s current onboarding routes users to its Sui Spot CLMM pools. The AMM-LP basis is therefore independently sufficient even before considering the separate Sui chain disposition.
Control and exit applicability
The LP controls its chosen pair and range, but Bluefin contracts and pool parameters govern fee accounting and swaps. A position outside its range becomes inactive and stops earning fees while becoming concentrated in one asset. Exit requires removing the position at the then-current pool composition and accepting price impact and token liquidity; it does not restore the original deposit mix.
Why the class rule decides
The shared v1 AMM-LP dossier controls because the reviewed product is paired concentrated liquidity. Reopen only if Bluefin ships a separately identifiable product with no AMM inventory rebalancing or impermanent-loss exposure. That product would need its own mechanism, chain, controls, audits and incidents, fee source, ordinary and stressed exit test, and comparison with holding the assets directly.

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

Inherited controls
The verdict above grades the protocol layer. Every position also inherits the asset it holds and the chain it settles on. The least safe layer sets the position’s grade, and the position table names which one that is.
