Apyee

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

Apyee is a non-custodial multichain USDC yield aggregator whose immutable ERC-4626 vaults route deposits into a whitelist of lending strategies including Aave v3, Compound v3, and Morpho vaults. TVL was about $17,282 at the 2026-08-16 survey, far below the registry’s $100 million floor. Rejected on size: one practice advising 100 households moves $1M to $8M into a venue on the same research, and below $100M TVL that book becomes the exit crush, whatever the protocol’s quality. A review at size would also face the delegated-allocation question that applies to automated routers.

Kill criteria: the events that revoke this verdict
• TVL sustained above $100M for 30 days

The research file

Materiality mechanism, applied

The threshold is a capacity constraint, not a quality judgment. A $2 million household with a 5-10% crypto sleeve and a 10-40% venue weight implies roughly $10,000 to $80,000 directed here; across 100 similar clients one practice can point $1 million to $8 million at a single venue on the same research. Below $100 million of protocol TVL, that book becomes the exit crush, and TVL itself is a generous capacity proxy rather than a promise of executable withdrawal: utilization, queues, unbonding, bridge depth and token liquidity can all leave less actually withdrawable than the headline figure implies. Small size does not itself indicate weak governance or team quality; the class rule stops short of that judgment because inadequate capacity for this distribution channel cannot be cured by otherwise-strong controls.

Mechanism applicability

Apyee routes USDC deposited in ERC-4626 vaults among whitelisted lending strategies including Aave V3, Compound V3, MetaMorpho, Fluid, Venus and Spark. Returns and losses therefore look through to downstream markets, collateral, oracles and strategy adapters.

Control and assurance applicability

Apyee states that vault bytecode is immutable and operators cannot withdraw user funds, which narrows custody risk but does not eliminate allowlist, allocation, integration or downstream protocol risk. The published Soken review supplies code-scope evidence, not economic or liquidity assurance.

Exit applicability

ERC-4626 redemption depends on available USDC and successful withdrawal from the active lending strategy. Aggregate TVL across four chains is not executable depth for one vault, especially if a downstream market is utilized, paused or impaired.

Why the materiality dossier decides

DefiLlama measured $17,282 across Base, Ethereum, Binance and Arbitrum on 2026-08-16, only 0.017% of the $100M floor. Reopen after TVL stays above $100M for 30 days, then verify bytecode, roles, allocation rules, every adapter, incidents and proposed-size exits.

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.
