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

Puffer is a liquid restaking protocol on Ethereum; its pufETH token represents restaked ETH. TVL was $45.3M at the 2026-08-14 survey, below our $100M materiality line, and size alone rejects it: one practice advising 100 households moves $1M to $8M into a venue on the same research, and at this size that book becomes the exit crush, whatever the protocol’s quality.

The research file

Mechanism applicability

Puffer’s official materials describe a native liquid-restaking protocol integrated with EigenLayer. A user deposits ETH and receives pufETH, whose return combines Ethereum proof-of-stake rewards with Puffer and EigenLayer restaking rewards while remaining usable in DeFi. That establishes liquid-restaking membership and layered validator, restaking and token-liquidity dependencies. It does not validate node-operator selection, restaking allocations, slashing exposure, contract roles or reward accounting.

Current observation and scope

The DefiLlama protocol API read on 2026-08-15 showed about $45.4M of tracked Puffer Stake TVL on Ethereum, below the shared v1 dossier’s $100M materiality gate. Puffer’s live staking application still offers ETH-to-pufETH liquid restaking, so the product identity remains current. Deployed-contract correspondence, governance and pausing authority, audits, incidents, validator concentration and EigenLayer service exposure remain expressly deferred.

Exit applicability

The live protocol exposes pufETH as a transferable liquid-restaking claim, so exit can occur through protocol withdrawal or a secondary pufETH market. Either path ultimately depends on liquid ETH, validator and EigenLayer withdrawal timing, and available token liquidity; the existence of a liquid token does not guarantee a low-slippage exit. At current tracked size, a sleeve-sized advised allocation could be material to the token’s available liquidity or withdrawal flow.

Why the class rule decides

The shared v1 below-materiality dossier controls this application before an individual restaking review is warranted. Reopen only after a reproducible survey shows at least $100M of Puffer Stake TVL continuously for 30 days. Then verify governance and upgrade controls, validator and AVS allocations, slashing and insurance design, audit remediation and incidents, reward accounting, and observed native and secondary exits under stress. Crossing the threshold would trigger diligence, not confer approval.

Sources

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.
