Aave v2 (Polygon)
One of 3 deployments of Aave v2 · also on Avalanche, Ethereum
Hover a figure for its basis and read. The market and every class, family and venue carry these same three, chosen by the published definitions, as of 2026-10-01. What each one measures →
Quantities are a contract-state read. No liquidation price is derived: no liquidation threshold (LLTV) is ingested for this venue. Its own documentation may publish one; this dataset does not read it, so no price is derived. That is a coverage gap in this estate, not a property of the venue. this venue pools borrowing across every collateral it accepts, so no BTC-specific debt exists to read — the contract-state rows carry debt_attribution 'unavailable' and no dollar figure. A market-wide borrow total would be a number about this venue, not about its bitcoin book, and it is not served as one.
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. Serving "duration: none" for a pool would read as a missing measurement rather than a property of the instrument.

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?

A lower bound on the venue's age. Not typed, and not a claim about its longevity. |
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 (v1 §6.4). |
|---|---|
| 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 (OB2-F1). 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 (criteria §0.6).) |
| 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 migration 153 and WEEKLY at past blocks back to 2021-04-05 (migration 152). Collateral only — the venue's debt is not read. composition: none — Not observed: composition is loan-level. |
Backing chain
backing_chain (v1 §9.5, D29): 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.

There is no score on this page and none will be added. The criteria are published and versioned before any venue is measured against them, and this venue's row is produced by the same pipeline as every other.
Access routes
Not yet surveyed. No one has looked for an MCP server for this venue. That is not the same as having looked and found none, and this row will not say the second while meaning the first. The listing criteria are published.
How this venue compares depends on what you'd borrow, for how long, against what. That's a question for your AI, with this data behind it.
