Both Morpho and Surge Credit use similar custody approaches: smart contract (wrapped btc via custodial bridge) and collaborative multisig (taproot vault, 3-of-4 signer network) respectively. 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. Surge Credit uses Collaborative multisig (Taproot vault, 3-of-4 signer network). Multiple key holders must coordinate to move funds, reducing single-point-of-failure risk but still requiring trust in the key coordination process.
Morpho has no margin-call mechanism: positions become liquidatable automatically the moment LTV crosses 86%, with no warning threshold or response window. Surge Credit has no margin-call mechanism: positions become liquidatable automatically the moment LTV crosses 90%, with no warning threshold or response window.
| Threshold | Morpho | Surge Credit |
|---|---|---|
| Max Starting LTV | 86% | 50% |
| Margin Call | None | None |
| Margin Call Window | None — automated liquidation | None — automated liquidation |
| Liquidation | 86% LTV | 90% LTV |
Morpho: 0.0 percentage point buffer between starting LTV (86%) and liquidation (86%). Surge Credit: 40.0 percentage point buffer between starting LTV (50%) and liquidation (90%). Surge Credit provides a wider safety margin.
