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

Ajna V2 is a noncustodial, permissionless peer-to-pool lending system without governance or external price feeds. Lenders choose price buckets, while liquidation debt can freeze withdrawals from affected top-of-book buckets. The reproducible 2026-08-16 DefiLlama survey measured about $0.45M supplied and $0.03M borrowed across eleven chains, while Ajna’s landing page simultaneously displayed $83.74M TVL without a chain breakdown or observation timestamp. Both figures remain below the $100M materiality floor, and the unreconciled denominator reinforces the need for a full review before use.

The research file

Mechanism applicability

Anyone can create an Ajna pool for ERC-20 or ERC-721 collateral. Lenders deposit quote tokens into price buckets that express the valuation at which they are willing to lend; borrowers post collateral and draw against pool liquidity. Interest, auctions and lender-selected prices replace governance-set listings and external price oracles.

Loss, control and exit applicability

The protocol is noncustodial and designed to run without governance, but permissionless pool creation transfers asset, market and parameter selection to users. The whitepaper states that quote-token buckets within liquidation debt are frozen: depositors cannot withdraw or move funds until the loan is restored or the auction settles. Exit capacity therefore depends on bucket position, pool liquidity, collateral realization and active liquidation state.

Current observation and perimeter

The DefiLlama API read on 2026-08-16 classified Ajna V2 as Lending and reported approximately $0.45M supplied and $0.03M borrowed. Ethereum held about $0.43M; Arbitrum, Base, Rari and Optimism were the next nontrivial deployments, with smaller Polygon, Hemi, Avalanche, Filecoin, Blast and Binance balances. Ajna’s official landing page simultaneously displayed $83.74M TVL without a chain breakdown or timestamp. This record uses the reproducible survey perimeter but flags the unresolved denominator mismatch.

Why the materiality dossier still applies

DefiLlama measures about 0.45% of the $100M floor and even the much larger official-site display is only 83.74% of it, with neither source evidencing 30 consecutive days above the threshold. Reopen only after supplied TVL is reconciled and remains above $100M for 30 days, then review pool concentration, bucket depth, bad-debt and auction history, collateral liquidity and tested withdrawal capacity.

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.
