Arch and Morpho take fundamentally different approaches to collateral custody. Arch uses Custodial (Anchorage, qualified custodian). Your Bitcoin is held by Arch and could be at risk in the event of a hack, insolvency, or regulatory action. Morpho holds collateral in audited smart contracts rather than with a single lender, but borrowing requires wrapped Bitcoin (WBTC or cbBTC) — your underlying BTC is held by the wrapper's custodian (BitGo/BiT Global for WBTC, Coinbase for cbBTC), reintroducing custodial bridge risk. Smart-contract and oracle risk also apply.
Arch triggers margin calls at 70% LTV and liquidates at 80% LTV. Morpho has no margin-call mechanism: positions become liquidatable automatically the moment LTV crosses 86%, with no warning threshold or response window. Arch gives borrowers 24 hours to respond to a margin call before any collateral is sold.
| Threshold | Arch | Morpho |
|---|---|---|
| Max Starting LTV | 60% | 86% |
| Margin Call | 70% LTV | None |
| Margin Call Window | 24 hours | None — automated liquidation |
| Liquidation | 80% LTV | 86% LTV |
Arch: 20.0 percentage point buffer between starting LTV (60%) and liquidation (80%). Morpho: 0.0 percentage point buffer between starting LTV (86%) and liquidation (86%). Arch provides a wider safety margin.
