ZEROBASE CeDeFi

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

ZEROBASE is a stablecoin staking product that pairs basis-trading yield with zero-knowledge proofs of its positions, deployed across six chains including BSC and Ethereum. At $53M TVL at the 2026-08-14 survey it sits below our $100M materiality line. Rejected on size: an advisory book moved into a venue this size on the same research becomes the exit crush, whatever the protocol’s quality. If it crosses the line and holds, the reopened memo would face the questions every basis-trade dollar faces: what happens when funding inverts, and whether redemptions gate exactly when everyone wants out.

The research file

Mechanism applicability

ZEROBASE documentation describes zkStaking as a stablecoin product whose off-chain returns come from capital-efficient strategies. Its staking architecture says users deposit USDC or USDT into a vault for LP shares, while capital can be transferred through Ceffu for trading-arbitrage or hedge-fund activity; zero-knowledge and trusted-execution evidence is intended to attest strategy behavior. That off-chain basis and custody path establishes CeDeFi yield applicability without validating the attestations or strategy.

Current observation and scope

The DefiLlama protocol API read on 2026-08-15 showed about $52.8M of tracked TVL across its listed multi-chain footprint, below the v1 dossier’s $100M threshold. The current ZEROBASE overview continues to identify stablecoin-funded off-chain yield, so the class membership remains supported. Custodian account segregation, strategy counterparties, proof coverage, governance, audits, realized losses and incident history remain expressly deferred.

Exit applicability

ZEROBASE’s staking documentation describes a standard withdrawal request followed by a 14-day buffer during which robots source funds, generally from Ceffu, and a flash withdrawal charging 0.5% only when the deposit contract has enough liquidity. Redemption therefore depends on off-chain position liquidation and available on-chain cash rather than an unconditional stablecoin exit. At current size, a coordinated advised allocation could materially affect that buffer or queue.

Why the class rule decides

The shared v1 below-materiality dossier controls this application before an individual CeDeFi assessment is warranted. Reopen only after a reproducible survey shows at least $100M of protocol TVL continuously for 30 days. The resulting review must verify custody and exchange counterparties, the exact strategy and hedge constraints, proof-to-position coverage, control and incident evidence, and observed completion of normal and flash redemptions under stress. Crossing the threshold would not itself make the product acceptable.

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.
