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

cSigma Finance is a commercial lending protocol on Ethereum that connects stablecoin lenders to global borrowers through managed credit pools and yield tokens. At the 2026-08-16 survey it held about $21.6M, primarily on Arbitrum with smaller Ethereum, Hedera and Base balances, under our $100M materiality floor. One practice advising 100 households moves $1M to $8M into a venue on the same research, and at this scale that book becomes the exit crush, so the file is rejected on size without a full review. At scale it would face the off-chain credit questions: the borrowers are commercial businesses whose books cannot be inspected on-chain.

The research file

Mechanism applicability

cSigma pools connect stablecoin lenders to real-world businesses and tokenized private-credit portfolios. Deposits mint pool or yield-bearing share tokens while managers deploy capital into loans; newer csUSD can dynamically allocate between RWA credit markets and onchain strategies. Borrower cash flows, collateral and enforcement remain offchain even though share accounting and settlement are onchain. The measured system remains below the shared version-1 materiality threshold.

Current observation and perimeter

The DefiLlama protocol API read on 2026-08-16 classified cSigma as RWA Lending and reported approximately $21.60M: $21.12M on Arbitrum, $0.47M on Ethereum, about $2,000 on Hedera and a nominal Base balance. cSigma’s current site separately reports $13.8M TVL and more than $80M of originated loans, illustrating a denominator or timing mismatch. The registry adopts the reproducible survey value and corrects the stale Ethereum-only perimeter.

Control and exit applicability

Pool managers select borrowers, deploy capital, administer whitelists and help return funds; KYC and KYB backend services determine eligibility, with final access enforcement onchain. cSigma advertises borrower assessment, first-loss capital, collateral and other contractual safeguards, but these require offchain verification and enforcement. Withdrawals use available reserves first and then a FIFO queue fulfilled by repayments or returned capital; queued timing is not guaranteed.

Why the class rule decides

Growth from roughly $0.6M to $21.6M is meaningful, but a $1M to $8M advised book would still equal about 5% to 37% of the entire measured system before borrower repayment or queue stress. The shared version-1 below-materiality dossier therefore decides first. Reopen after reconciled TVL remains above $100M for 30 consecutive days, then review borrower-level financials and verification, legal claims and jurisdictions, manager and KYC controls, defaults and recoveries, proposed-size queues and named liquid onchain or regulated-credit alternatives.

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.
