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

Blend is lending infrastructure on Stellar; anyone can create an isolated lending market with it, and v2 adds pool-specific reserves, a backstop and Dutch auctions for liquidation and bad debt. DefiLlama records about $137.5M supplied and $53.0M borrowed on Stellar at the survey. Those mechanics do not cure the settlement-layer control that rejected Stellar. This is a chain disposition, not an allegation that Blend is insolvent or insecure.

The research file

Reachability, not protocol quality

The rejection sits at the settlement layer, not the application: every state transition, oracle update, liquidation and withdrawal here ultimately depends on validator or sequencer operation, finality, bridge security and emergency controls the protocol team cannot neutralize by shipping audited contracts. Quoted protocol TVL and DEX depth can remain visible on-chain while operational exit is unavailable if the chain cannot finalize or the bridge route is impaired. The same protocol on an approved deployment would receive its own individual review.

Mechanism

Blend v2 lets pool creators select reserves and parameters. Suppliers fund isolated lending pools; borrower liquidations, bad debt and backstop interest are processed through public Dutch auctions. The backstop is pool-specific rather than a guarantee from Blend.

Control and evidence

Pool creators and backstop participants control market economics, while Stellar ultimately settles every contract and issued asset. Blend publishes v2 contracts, audits and a Certora formal-verification report. Those are meaningful protocol controls, but they cannot override Stellar issuer authorization, clawback or protocol-level freeze powers.

Exit consequences

A supplier may withdraw only available reserve liquidity; utilization or bad debt can delay realization. Any received Stellar-issued asset remains subject to its issuer flags, and CAP-77 gives the validator quorum an implemented freeze mechanism for accounts, trustlines and contract data.

Why the class rule decides

The rejected-chain dossier is dispositive before isolated-pool underwriting because every deposit, auction and withdrawal settles on Stellar. Review reopens only if Blend builds material liquidity on an approved chain or the Stellar verdict changes.

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.

ChainVerdictGradeControl constraint
StellarRejected freezable freeze is native at every level: issuers hold revocation and clawback flags on their assets, and since Protocol 26 the validator quorum can vote to freeze specific accounts and trustlines on-chain (CAP-77).
