Avon MegaVault
Rejected venues wait the longest for re-review; a rejection has to earn another look before the scheduled date.
Avon is an order-book credit layer with isolated risk per strategy; MegaVault is its ERC-4626 USDm yield vault on MegaETH. TVL was about $15,691 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.
- 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
Avon describes MegaVault as an ERC-4626 USDm yield vault within an order-book credit system with strategy-level isolation. Depositors therefore rely on the selected credit strategies, borrowers, collateral and accounting rather than a native risk-free USDm return.
Control and assurance applicability
Strategy admission, risk parameters and implementation controls define the loss perimeter even when strategies are isolated. A published Zellic audit is relevant code assurance but does not prove borrower performance, collateral realization or current administrator safety.
Exit applicability
ERC-4626 shares express a redemption interface, not guaranteed cash capacity. Withdrawals still depend on idle USDm and liquidation or repayment of strategy assets; a full review must test utilization, queues and proposed-size redemption.
Why the materiality dossier decides
DefiLlama measured $15,691 entirely on MegaETH on 2026-08-16, only 0.016% of the $100M floor. Reopen after TVL stays above $100M for 30 days, then map strategies, roles, realized losses, audit remediation and stressed exits.

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.
