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

Yield Yak Aggregator is a mixed wrapper perimeter, not one fixed farm. Its live adapter counts enumerated farm contracts on Avalanche, Arbitrum and Mantle plus Milk vaults on Avalanche and Base; official materials describe autonomously rebalanced diversified vaults as well as fixed farm compounders and product-specific leverage loops. The DefiLlama endpoint reported about $13.24M on 2026-08-15. Because the aggregate label does not pin an advised client to an immutable venue and strategy set, the v1 delegated-allocation dossier controls regardless of size.

The research file

Current product and aggregate perimeter

Yield Yak operates many separate farm contracts and newer Milk vaults rather than one homogeneous position. The current adapter obtains farm lists for Avalanche, Arbitrum and Mantle, reads each deposit token and total deposits, and separately adds Milk-vault shares on Avalanche and Base. Official documentation distinguishes optimal auto-compounders from Intelligent Vaults that autonomously optimize a diversified allocation across protocols.

Current observation and classification boundary

The DefiLlama protocol API read on 2026-08-15 classified Yield Yak Aggregator as a Yield Aggregator and reported approximately $13.24M across Avalanche, Arbitrum, Mantle and Base, excluding separately reported YAK staking. Some named single-asset strategies recursively lend and borrow up to seven times, but that product-specific mechanism is not a defensible blanket description of every farm. The shared record is classified by its aggregate ability to expose holders to changeable downstream strategies; leverage and AMM rules still apply to individual products where present.

Control, loss and exit applicability

Farm contracts compound rewards and may swap them through external venues, while Intelligent Vault strategists or automation can rebalance among supported protocols. Each deposit inherits the chosen farm or vault contract, underlying asset, downstream protocol, reward route and withdrawal liquidity. Yield Yak expressly identifies underlying-platform smart-contract risk; leveraged farms add liquidation risk, and LP farms add changing inventory and impermanent-loss risk.

Why the shared dossier decides

The v1 delegated-allocation dossier controls the aggregate protocol record because an adviser cannot infer one stable exposure, venue allowlist or exit path from the Yield Yak label and cannot guarantee that a managed vault preserves today’s weights after deposit. Reopen only for a named vault with an immutable adviser-compatible allowlist and caps, no manager substitution, continuously verifiable holdings and debt, complete authority and incident evidence, and an observed proposed-size stressed withdrawal.

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.
