KyberSwap FairFlow

Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.

KyberSwap FairFlow is a swap hook built on Uniswap v4 pools that routes a share of arbitrage value to liquidity providers on top of trading fees. The hook changes LP compensation, not the underlying paired market-making inventory or impermanent-loss path, so the version-1 amm-lp dossier is dispositive. The current adapter returns no TVL samples and only an Ethereum label; this memo does not convert that missing capacity evidence into a fabricated size finding.

Kill criteria: the events that revoke this verdict
• Ships an economically separate product whose return does not require paired or synthetic market-making inventory
• Current deployed pool identities, chain perimeter, hook authorities and proposed-size removal capacity become independently observable

The research file

Mechanism applicability

KyberSwap describes FairFlow as a Uniswap v4 swap hook that captures arbitrage value and redistributes it to LPs as Equilibrium Gain in addition to ordinary LP fees. The hook does not require separate LP-token staking, so the client claim remains the underlying Uniswap v4 liquidity position rather than a detached yield instrument. Paired pool inventory and fee generation directly meet the shared v1 amm-lp dossier.

Current observation and perimeter

The DefiLlama protocol API read on 2026-08-15 still classified FairFlow as Yield Aggregator but returned no current TVL samples and listed only Ethereum, versus seven chains in the prior survey. KyberSwap’s current documentation and official Earn route still present FairFlow pools, so the memo records an active but empty or unmeasured Ethereum adapter rather than declaring the product archived. The registry perimeter is narrowed to the current survey evidence.

Control and exit applicability

LPs retain their underlying Uniswap v4 position and do not have to stake it to receive the hook’s additional distribution. Pool price, hook execution and swap flow still determine inventory and withdrawal value; capturing more arbitrage value can improve compensation but cannot remove impermanent loss, out-of-range exposure or exact-pool exit depth. The lack of current adapter TVL means there is no observed capacity for an advised sleeve.

Why the class rule decides

FairFlow can return more arbitrage value to an LP but cannot remove the LP’s paired inventory, range and divergence-loss exposure. The shared v1 amm-lp dossier therefore controls independently of size. Current documentation and an official Earn route evidence continued product presentation, but the adapter supplies no current pool samples or executable capacity; live deployed pool identity, chain perimeter and proposed-size removal remain explicit lifecycle and capacity blockers rather than a zero-TVL inference.

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.
