JustLend v1 (Tron)
Takes as collateral: bitcoin and ether
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 (no bitcoin in 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.
10 of 10 criteria researched. What the criteria are →
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. This venue runs no contracts, so there is no market state to read — the absence is a property of the venue class, not a gap.
Price
What does credit cost here, and how is the price formed?
| Rate formation | algorithmic_utilisationsourceJustLend on Tron (chain 728126428) — each jToken names an interestRateModel() evaluated on cash, borrows and reserves: a function of utilisation, algorithmic_utilisation. The curve each model implements was not read. |
|---|---|
| Term structure | open_endedsourceJustLend jToken markets on Tron (chain 728126428) — borrow()/repayBorrow() carry no maturity; a position persists until repaid or liquidated. |
| Rate certainty | variablesourceJustLend jToken markets on Tron (chain 728126428) — each market accrues at the rate its interestRateModel() returns for the market's current cash, borrows and reserves; nothing is fixed at origination. |
Quality
What stands behind a position, and what can change under the reader?
| Oracle dependency | multiplesourceJustLend Comptroller TGjYzgCyPobsNS9n6WcbdLVR9dH7mWqFx7 on Tron (chain 728126428) → oracle() = TGnYnSn4G9PgWFj7QQemh4YMZKp3fkympJ (read 2026-09-30). One oracle contract prices every market, from a source per asset that governance can replace. A pooled venue's solvency depends on the feeds of every market an account has entered, not on one. |
|---|---|
| Default & liquidation | thresholdsourceJustLend Comptroller TGjYzgCyPobsNS9n6WcbdLVR9dH7mWqFx7 on Tron (chain 728126428) — an account can be liquidated once its borrow exceeds the sum of its collateral at each market's collateral factor (markets(token).collateralFactorMantissa); a liquidator repays up to the close factor (50%) of a borrow and seizes jToken collateral. |
| Custody & backing | protocol_custodialsourceJustLend jToken markets on Tron (chain 728126428) — mint() transfers the underlying to the market's own contract; the depositor holds the jToken as a claim rather than the asset. |
| Recourse | non_recoursesourceJustLend Comptroller TGjYzgCyPobsNS9n6WcbdLVR9dH7mWqFx7 on Tron (chain 728126428) — liability is bounded by the collateral a liquidator can seize; no function pursues a borrower beyond it, and a shortfall stays in the market as bad debt. |
| Track record | 50 months observedsourceDerived from the first aggregator observation this dataset holds for the venue (defi_rates_llama, 2022-07-07; the registry holds no first_date for it). This is a LOWER BOUND on the venue's age, not the age itself: a venue trading long before the aggregator began listing it reads short here. The observer is the aggregator, not the venue's own contracts. Not typed, and not a claim about the venue's longevity. |
Composition
Who and what makes up this market?
| Collateral accepted | BTC markets (2): BTCTRON (Poloniex's wrapped BTC), WBTCsourceJustLend Comptroller TGjYzgCyPobsNS9n6WcbdLVR9dH7mWqFx7 on Tron (chain 728126428) — getAllMarkets() and markets(token) (registry/resolution/2026-09/comptroller_forks.json; root docs.justlend.org/developers/deployed_contracts). 24 markets, read 2026-09-30. Bitcoin markets: jBTC TLeEu311Cbw63BcmMHDgDLu7fnk9fqGcqT over BTC TN3W4H6rK2ce4vX9YnFQHwKENnHjoxb3m9 (8 decimals) — collateral factor 75%, 6,582 supplied, 18.8 borrowed; jWBTC TVyvpmaVmz25z2GaXBDDjzLZi5iR5dBzGd over WBTC TYhWwKpw43ENFWBTGpzLHn3882f2au7SMi (8 decimals) — collateral factor 75%, 89.4 supplied, 0.017 borrowed. ⚠ "BTC" here is the TRC20 token NAMED "Bitcoin" — not native bitcoin but Poloniex's wrapped token, BTCTRON: "BTCTRON is a type of wrapped Bitcoin token that exists on the TRON blockchain... On Poloniex, you will always be able to redeem BTCTRON 1:1 to the value of Bitcoin (BTC)" (medium.com/poloniex, 2020-10-01). Poloniex is issuer and holder; no attested proof of reserves for the token was found. 17,545 are issued (TronScan, read 2026-09-30), so JustLend holds over a third of them. asset_peg measures it as pegged (33 bps). NOTE: the pool is multi-collateral, so a bitcoin market'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: partial — Observed through the aggregator (DefiLlama). The aggregator's rows are each pool's published borrow and supply rates as it reports them — not a read of the venue's own contracts, and not checked against one. As of 2026-10-01. quantity: partial — Observed through the aggregator (DefiLlama): bitcoin collateral is the supplied amount of each pegged-bitcoin reserve, converted at the day's bitcoin reference, and debt is the borrowed amount per pool or vault. Neither is a read of the venue's own contracts. As of 2026-10-01. composition: none — Not obtainable from an aggregator — composition is loan-level and requires event ingestion, which is not planned for this venue. |
What the loans are denominated in
Not yet established for this venue — which is not the same as dollars.
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.

This row said the BTC JustLend takes is WBTC on TRON, held by BitGo — and it is not: the token (TN3W4H6rK2ce4vX9YnFQHwKENnHjoxb3m9) is Poloniex's BTCTRON, as the `BTC` / chain Tron row above records. JustLend lists WBTC on TRON as a separate market. Because the backing chain reads this block before the symbol rows, its JustLend links named BitGo until this correction.

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.
