# Lending-market parameter report: WXDC collateral / USDC loan (example parameters)

> Factual research for B2B parameter review; not investment advice or a recommendation.

Paid by: nobody (internal sample, not commissioned). If this report is shared, it states who commissioned it.

Market parameters (LLTV, LTV grid) are **illustrative config inputs**, not the parameters of a live market (PrimeFi XDC WXDC/USDC parameters were not found in public docs and are not read on chain here).

| Loan token | USDC `0xfa2958cb79b0491cc627c1557f441ef849ca8eb1` (decimals 6) | symbol()/decimals() eth_call |
| Oracle feed (proxy) | XDC/USDC `0x0261911548dc291BDf6287e73DFf9B1BF8B08fE8` | description() eth_call |
| Oracle aggregator | `0xe8860f90268aa933bbceedff1711c21fe0a3dea7` | aggregator() eth_call |
| LLTV | 62.5% | market config (illustrative) |
| Liquidation incentive factor | 1.1268 | Morpho Blue formula min(1.15, 1/(0.3·LLTV+0.7)) |
| Feed quote vs loan token | feed "XDC/USDC" · loan USDC | Plugin XDC/USDC feed; quote = USDC (FeedExplorer /api/feeds.json) |

## 2. Oracle quality

| Metric | Value | Source / timestamp |
|---|---|---|
| Latest answer | 0.0348743 | latestRoundData() at block 108575591 |
| Latest round id | 18446744073709568653 | latestRoundData() |
| Last update | 2026-10-21T14:50:18Z | latestRoundData().updatedAt |
| Age at observation (staleness) | 8 min | observedAt − updatedAt |
| Rounds read | 25 (since 2026-10-21T06:36:02Z) | getRoundData() walk-back |
| Update interval median / min / max | 15 min / 14.7 min / 30.6 min | consecutive updatedAt in rounds read |
| Rounds in last 24 h (within rounds read) | 25 | rounds read |
| Round-to-round answer change median / max | 0.483% / 1.87% | rounds read |
| Registry deviation threshold | 0.2% | FeedExplorer /api/feeds.json (Plugin job registry fields, FeedExplorer health), generated 2026-10-21T14:53:56Z; unit per FeedExplorer (percent) |
| Registry poll timer | 15 min | same; unit per FeedExplorer (minutes) |
| Registry min. oracles | 1 | same |
| Data providers listed (count) | 3 | same |
| Registry API status | Active | same |
| FeedExplorer uptime 7d / 30d | 96.6% / 96.6% | same (FeedExplorer observation schedule) |

## 3. LLTV and liquidation buffer

Price drop to liquidation = 1 − LTV / LLTV (collateral price in loan-token terms, debt value constant). LLTV = 62.5%.

| Position LTV | Price drop to liquidation | Oracle answer at liquidation |
|---|---|---|
| 40% | 36% | 0.02231955 |
| 50% | 20% | 0.02789944 |
| 60% | 4% | 0.03347933 |

Liquidation incentive factor 1.1268 (Morpho Blue formula min(1.15, 1/(0.3·LLTV+0.7))); LIF × LLTV = 0.7042 (above 1 means the incentive at LTV = LLTV exceeds the collateral value).

For reference: largest round-to-round oracle change in the rounds read = 1.87%; median update interval = 15 min.
