Avon MegaVault
Avon is an order-book credit layer with isolated risk for each 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 size floor. The protocol is below the size floor, so we have not opened an individual review. One practice advising 100 households could move $1M to $8M into a venue based on the same research. At this TVL, that book becomes the exit crush, whatever the protocol’s quality.
- 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
Materiality mechanism, applied
The size floor is a capacity limit, not a judgment of quality. 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 one venue based on the same research. Below the protocol TVL size floor, that book becomes the exit crush. TVL is itself a generous measure of capacity, not a promise that clients can withdraw: utilization, queues, unbonding, bridge depth and token liquidity can all leave less available than the headline figure implies. Small size does not itself show weak governance or team quality. The class rule makes no such judgment because strong controls cannot cure inadequate capacity for this distribution channel.
Mechanism applicability
Avon describes MegaVault as an ERC-4626 USDm yield vault in an order-book credit system that isolates each strategy’s risk. Depositors therefore rely on the chosen credit strategies, borrowers, collateral and accounting, not on a native risk-free USDm return.
Control and assurance applicability
The rules for admitting strategies, the risk settings and the code controls define the possible losses even when strategies are isolated. A published Zellic audit gives relevant evidence about the code, but it does not prove borrower performance, collateral realization or the current safety of administrator access.
Exit applicability
ERC-4626 shares provide a way to request redemption, not guaranteed cash capacity. Withdrawals still depend on idle USDm and the liquidation or repayment of strategy assets; a full review must test utilization, queues and redemption at the proposed size.
Why the materiality dossier decides
DefiLlama measured $15,691 entirely on MegaETH on 2026-08-16, only 0.016% of the size floor. The individual review will not open until TVL stays above the size floor for 30 days. We would then map strategies, roles, realized losses, audit fixes and stressed exits.
Research status
This is a capacity-unproven record for Avon MegaVault, 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.
