Ether.fi Cash Liquid is outside the current firm shelf under the version-1 delegated-allocation policy. The Phase 2 survey attributed approximately $134.2M to the Cash Liquid product. Liquid accepts a single deposit, deploys it across a basket of DeFi strategies, automatically rebalances the basket, and compounds the results into the vault share. This applies a published class rule to one protocol; it does not claim that every contract or operator behind Ether.fi Cash Liquid is defective.

The research file

Mechanism and why the rule applies

Liquid accepts a single deposit, deploys it across a basket of DeFi strategies, automatically rebalances the basket, and compounds the results into the vault share. On its own facts the deployment matches the mechanism the dossier describes. The Phase 2 survey attributed approximately $134.2M to the Cash Liquid product. This record keeps enough protocol evidence to show the rule applies and leaves the shared economic argument in the pinned dossier; it is not a separate flagship review.

Control and incident boundary

Strategy selection, weights, integrations, and rebalancing remain continuing allocator decisions even when the vault contracts and displayed allocations are transparent. Those controls and the available incident record may change operational risk, but they do not remove the property the rule turns on. No clean-record claim is used as proof of safety: a young deployment can have little adversarial history, and an established deployment can execute its intended economics without an exploit while still remaining unsuitable for the advised sleeve.

Exit and current measurement

Redemption depends on the vault buffer and the ability of the active underlying strategies to return assets; leverage or liquidation risk can exist inside strategies the client did not select directly. Aggregate TVL is an accounting measure rather than a promise that the exact client position can be unwound at the displayed value. The rule holds until a stated reopen condition is observed and a new review measures the exit at the proposed size instead of inferring it from a dashboard total.

Comparison and decision

Direct positions in shelf-eligible venues preserve look-through into the economic claim and let the advisor apply client-specific constraints instead of outsourcing the allocation decision to a changing basket. The comparison is made at the exposure level, not by brand or headline rate. The published dossier is preferable to repeating the same class judgment with slightly different wording for every venue; the protocol-specific sources retained here make the classification reproducible and the reopen criteria observable.

Class rule

The delegated allocation 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.

Sources

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.
