YO Protocol

We reject YO because it is below the size floor, and we will not open an individual review until it clears that floor. YO is a multi-chain yield optimizer that rebalances deposits across venues on Base, Ethereum, Solana, and Arbitrum. TVL was $34.5M at the 2026-08-14 survey. 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. If we reopen the file, we would weigh it as delegated allocation: the depositor inherits whatever the optimizer holds, and allocation across vetted venues is the service we charge for ourselves.

Review triggers: events that reopen the verdict
• TVL sustained above the retired TVL threshold for 30 days

Watched nightly: a warning on its venues or files, or a cited document that changes, reopens the memo. The first confirmation is due 2026-11-15.

The research file

Mechanism applicability

YO documentation describes ERC-4626 yoVaults that issue transferable yoTokens and place deposits in whitelisted yield pools across supported chains. Operators and an allocation algorithm set target weights and rebalance positions. This makes it a delegated yield aggregator: a depositor inherits the vault’s changing underlying venues, smart contracts, and operator decisions. It does not prove the merits of any current vault allocation or downstream protocol.

Current observation and scope

The DefiLlama protocol API read on 2026-08-15 showed about $34.1M of tracked YO Protocol TVL across Base, Solana, Ethereum and Arbitrum, below the shared v1 dossier’s size floor. We will not open an individual review until it clears that floor. Current official documentation continued to describe active vault allocation and rebalancing. We have not reviewed vault holdings, chain-specific liquidity, privileged roles, audit coverage, incidents, incentive dependence, or downstream risk.

Exit applicability

YO says withdrawals below 5% of a vault’s TVL can be instant when enough liquid assets are available. Larger withdrawals may require strategy divestment for up to 24 hours through its redemption process. Exit capacity therefore varies by vault and depends on downstream liquidity. At the current aggregate size, an advised position could be material to one vault even when the protocol-wide number appears adequate.

Why the class rule decides

The shared v1 below-materiality dossier governs this case. Open an individual review only after reproducible surveys show protocol TVL above the size floor continuously for 30 days and live vault allocations remain observable. Then review each vault separately for allocations, governance and operator controls, contracts and audits, downstream eligibility, incidents, fees and incentives, and observed instant and asynchronous exits. Also apply the separate delegated-allocation rule. Clearing the floor would trigger review, not approval.

Research status

This is a capacity-unproven record for YO Protocol, not a quality rejection or approval. Reported TVL says how big the venue is, not what the client owns, who can change the rules, or how a position exits at a proposed size. The individual review opens when the protocol clears the size floor.

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.
