Takes as collateral: bitcoin and ether
One of 3 deployments of Aave v2 · also on Avalanche, Ethereum
Events for this venue: dated moves past a published rule and levels crossed.
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 — the whole pool's lending against every collateral it takes (bitcoin is 25.6% of the pool's collateral) — not debt against bitcoin, and no dollar of it is assigned to bitcoin without an account-level read.
- Liquidation threshold — the loan-to-value at which the venue liquidates a bitcoin position, not a price: no bitcoin book is read at this venue to turn it into one (a pool's debt has no collateral of its own until its accounts are read).
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.
No BTC market rows are served for this venue. It runs contracts, so the absence is this dataset’s, not the venue’s.
Price
What does credit cost here, and how is the price formed?

Composition
Who and what makes up this market?
| Collateral accepted | BTC reserves (1): WBTCsourceAave v2 LendingPool 0x8dFf5E27EA6b7AC08EbFdf9eB090F32ee9a30fcf on Polygon PoS (chain 137), addresses provider 0xd05e3E715d945B59290df0ae8eF85c1BdB684744, read at block 94762881 (registry/resolution/2026-10/historical_cells.json) — the WBTC reserve (aToken 0x5c2ed810328349100A66B82b78a1791B101C9D61) holds 62.02 WBTC and is FROZEN (configuration bit 57; borrowing disabled): no new supply or borrowing, existing positions remain and can be liquidated. NOTE: the venue is POOLED and multi-collateral, so a BTC reserve's presence does not mean a given borrow is secured by it. |
|---|---|
| Book depth & concentration | unknown (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: none — Not observed: this venue's rates are not read. It is registered for its collateral history. quantity: partial — Observed through the venue's own contracts: the supplied amount of its bitcoin reserve, read DAILY at a recorded block since 2026-10-01 and WEEKLY at past blocks back to 2021-04-05. Collateral only — the venue's debt is not read. composition: none — Not observed: composition is loan-level. |

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.
