Zentra Finance

Zentra Finance is a Citrea-only money market whose deposits, borrows, liquidations and withdrawals require Citrea execution and cBTC gas. Citrea has not passed the adviser chain review, so the version-1 rejected-chain dossier is decisive regardless of the approximately $1.93M supplied and $1.49M borrowed observed on 2026-08-15.

Review triggers: events that reopen the verdict
• The Citrea chain verdict changes or the exact Zentra market deploys on an approved chain
• The reopened market supplies verified contracts, authorities, collateral, oracles, utilization, liquidation, incident and proposed-size withdrawal evidence

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

Mechanism and chain applicability

Zentra is an Aave-derived overcollateralized money market deployed on Citrea. Lenders supply ctUSD, wcBTC or USDC, borrowers pledge collateral, oracle prices drive health and liquidators repay underwater debt. Official onboarding requires a Citrea-compatible wallet, Citrea-bridged assets and cBTC gas, so every position directly meets the shared v1 rejected-chain dossier.

Current observation and lifecycle

The DefiLlama protocol API read on 2026-08-15 classified Zentra Finance as Lending and reported approximately $1.93M supplied and $1.49M borrowed, entirely on Citrea. The current Zentra site and documentation publish live Citrea user flows and receipt-token contracts, while Citrea’s documentation identifies the network as an EVM-compatible Bitcoin rollup. This supports an active sole-chain record without implying that Bitcoin settlement substitutes for Citrea review.

Control, loss and exit applicability

Suppliers depend on exact-market utilization, borrowers, oracle and liquidation execution, pool and administrator controls, Citrea bridge availability and chain liveness. Documentation states withdrawals are subject to utilization. Receipt tokens on Citrea cannot be redeemed or moved to client custody without that chain and its cBTC gas path, regardless of Aave code ancestry.

Why the class rule decides

Zentra has no observed deployment outside Citrea, and Bitcoin data availability or settlement does not make Citrea contracts equivalent to a reviewed Bitcoin-native claim. The shared v1 rejected-chain dossier therefore controls before lending-market quality or size. Reopen only if Citrea passes adviser review or the exact market deploys on an approved chain, followed by contract, authority, collateral, oracle, utilization, liquidation, incident and proposed-size withdrawal tests.

Class rule

The rejected chain class is outside the approved structures, so every protocol in it is not approved until the rule changes. The rule is about the structure, not an adverse finding about this protocol, and it is not a client instruction. The events that would reopen it are listed with the memo.

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.
