Crypto collateral a lender can underwrite
DAVC turns a custodian's signed attestation into an on-chain certificate, values it with oracle prices and tier haircuts, and keeps checking it for the life of the mortgage.
- Custodian-signed attestations
- Balances are signed with the custodian's registered key, carry a strictly increasing nonce and expire.
- Certificates re-verified continuously
- Each certificate moves between Active, Deficient, Suspended and Expired as prices and attestations change.
- Tri-party control
- The lender proposes, the borrower accepts and the custodian acknowledges before collateral is pledged.
- LTV marked to market
- Warning at 70%, margin call at 80% and liquidation at 90%, with a cure period before any action.
- Custodian-executed liquidation
- The custodian sells, proceeds are applied to the loan, and collateral is released on payoff.
