function settleDebt(uint256 amount) external nonpayable
Settle bad debt in the Vault (in UA)
settleDebt won't revert if the Insurance balance isn't large enough to cover the debt amount, so from the point of view of the Vault it'll seem like the Insurance paid back the debt (while it's not). Yet Insurance will keep track of this accounting imbalance with the systemBadDebt variable. The first action of the Insurance will be to spur this debt before adding new funds to the Insurance balance (see fundInsurance).The UA amount transferred to the Vault is not assigned to any user's balance because the Vault cancels the debt of the individual user when calling
settleDebt (see settleLiquidationOnCollaterals).Name | Type | Description |
