IInsuranceFund

Functions​

repay​

  function repay(
  ) external

If insurance has negative accountValue of vault, will deposit amount to vault

distributeFee​

  function distributeFee(
  ) external returns (uint256 surplus)

If balance of InsuranceFund is over distributionThreshold, transfer diff to SurplusBeneficiary

Insurance Fund should only distribute revenues surplus earned on the platform. In other words, funds directly held in the Insurance Fund contract (insuranceFundWalletBalance) contributes to insuranceFundTotalBalance but not necessarily to surplus. Anyone can send funds to Insurance Fund and help it reach distributionThreshold sooner, but once surplus exceeds the revenues earned on the platform (insuranceFundFreeCollateral), sending more funds won’t increase surplus further
