Mezo Vaults issue receipt tokens while a named strategist deploys deposits into lending, real-world-credit, or other DeFi strategies. The August 15, 2026 survey reported about $7.57M on Mezo, but delegated allocation is the more fundamental rejection: the live venue and strategy can differ by vault and can be managed after deposit without a client-enforceable approved-protocol list. Reopen only for a named vault with fixed client-compatible limits and independently verifiable holdings, roles, losses, and exits.

The research file

Mechanism and class applicability

Mezo documents a vault flow in which the user deposits MUSD, BTC or another supported asset, receives a receipt token, and delegates deployment to the named strategist. Mezo-operated and external partner vaults can use different lending, real-world-credit or other DeFi strategies. That continuing strategy and venue selection directly satisfies the v1 delegated-allocation dossier.

Current observation and perimeter

The DefiLlama protocol API read on 2026-08-15 classified Mezo Vaults as a Yield Aggregator and reported approximately $7.57M on Mezo. Official materials list Mezo-managed savings and lending vaults alongside external vaults from partners such as August, UWI and Upshift, so the aggregate slug is not one stable underlying position.

Control, loss and exit applicability

The strategist rather than the receipt holder selects and operates the underlying strategy; Mezo expressly says it does not control external partner strategies. Each receipt therefore inherits the active contracts, assets, counterparties, valuation and withdrawal mechanics, while the aggregate protocol label does not let an adviser enforce a fixed venue allowlist or stressed-exit limit.

Why the shared dossier decides

The v1 delegated-allocation dossier controls regardless of current size because the adviser cannot pin the client to a continuously approved set of underlying exposures. Reopen only for a named vault whose immutable or client-specific allowlist and caps contain approved venues, with live holdings, debt, privileged roles, realized losses, valuation and executable withdrawal liquidity independently verifiable.

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.
