Dollar loans only: other currencies are separate books, never added in

Debt and rates count loans made in US dollars and dollar stablecoins. Loans in euros, francs, yen, ether or bitcoin itself are separate books, shown by currency on each venue, never added in.

  • Dollar debt against bitcoin — bitcoin-only borrowers only: $15m more is owed in dollars by 2,948 accounts posting bitcoin among other collateral, a bound never apportioned; $1m borrowed in other currencies is not added.
  • Aggregate LTV — the bitcoin-only borrowers' LTV, not the pool's: accounts posting bitcoin among other collateral are not in it.
  • Liquidates at — the bitcoin-only borrowers only (accounts posting other collateral are not in it); $2m of their debt sits in positions that liquidate within a 20% fall.
What “Liquidates at” is: one price for the whole book, not a forecast

"Liquidates at" is the bitcoin price at which this book, taken as one position, stops covering its debt at its liquidation thresholds — an aggregate, not a forecast: individual loans are levered differently and liquidate above it.

Loan duration is not a venue figure on an on-chain pool: these markets are open-term, and a position runs until it is repaid or liquidated. A fixed term exists only where the venue writes one — the custodial desks (cefi_credit_rates.term_days) and Gavel's auction, which is fixed-rate and fixed-term by construction.

Markets — as served, not a venue rate

One row per market, as the venue publishes them. These are market rates: combining them into a single venue rate is a weighting across this venue's markets, and choosing one here would be a methodology decision taken in a web page.

Every venue quotes in its own scale — Aave in ray APR, Compound per second, Sky as a per-second growth factor. All are converted here so figures from different venues are the same kind of number. Effective APY is exp(r) − 1.

Price

What does credit cost here, and how is the price formed?

AaveOracle holds one source per asset (setAssetSources) across every reserve, plus a fallback oracle, and governance can replace any of them. A pooled venue's solvency depends on all of the feeds backing the reserves an account touches, not on one.

(v3.3's DeficitCreated is not cited here: this estate has not observed it on this chain.)
Track record53 months observed
source
Derived from credit_venues.first_date (2022-03-11), the first observation this dataset holds for the venue. This is a LOWER BOUND on the venue's age, not the age itself: a venue trading long before we began reading it reads short here. Not typed, and not a claim about the venue's longevity.

Composition

Who and what makes up this market?

Collateral acceptedBTC reserves (1): WBTC
source
credit_aave_reserves, resolved on-chain from the Pool's reserve list on Polygon PoS (chain 137) and flagged is_btc by address. NOTE: Aave is POOLED and multi-collateral, so a BTC reserve's presence does not mean a given borrow is secured by it — attributing a borrow to Bitcoin specifically is a modelling decision.
Book depth & concentrationunknown (no per-venue counterparty count exists in this registry or in the comparison payload, so depth and concentration cannot be established. This is a gap in THIS DATASET, not in the venue, and is a different value from `undisclosed`, which would mean the venue does not publish it.)
Observability
price: full
quantity: full
composition: partial — Aave pools collateral across all of an account's reserves. Attributing a borrow to BTC collateral specifically is a modelling decision, not an on-chain read, and every composition figure for this venue must carry that label.

What the loans are denominated in

Borrowed inAssetsSize (USD equivalent)In the loan assetRead by
US dollars$16.9m—account-by-account pool read, 2026-10-13

Each currency is a separate book; the dollar equivalents compare sizes and are never added together.

Backing chain

Each link from what this venue takes as collateral down to the bitcoin it rests on, in order, with how each link was established.

How a chain is read, and what it does not claim

backing_chain: the ordered claims standing between a creditor and the coins, each link derived from a sourced fact already held and carrying it in `derived_from` — the custody cell, the venue's borrow card, or wrapper_registry.yaml for who holds the bitcoin behind a token. A `representation` link has one branch per token the venue takes; branches are alternatives, not a sequence. A link nobody has established is shown with status `incomplete` and names what is missing — it is never dropped, because a missing link omitted makes a long chain look short. `undisclosed` means the party does not publish it; `incomplete` means this dataset has not established it. NEVER SCORED AND NEVER COUNTED: no length, link count or ranking is published, and none should be derived — chain length and link transparency are orthogonal (ETP-backed margin is the longest chain here and every link of it is regulated). `recourse` is what the creditor holds beyond the chain. ⚠ Tokens are identified BY SYMBOL: the wrapper registry is not keyed by chain or address, so every `representation` link carries a `deployment` step that is incomplete — whether a token is native to the chain of the venue or a bridge receipt (one more link) is not established — and a symbol the registry knows to name a different token on a venue is shown unresolved, not given that wrapper's holders.

The generic axis set

Identical for every venue, identically computed. An axis that cannot be computed here renders its reason — never silently omitted, because an omitted axis says it was not considered. A figure that covers only part of what the axis asks is marked, with what it leaves out beneath it. Collateral, debt and the borrow and lend rates are the tiles at the top of this page.
