## Autotasks

The Huma protocol employs OpenZepplin's Autotasks to perform certain routine processes. There are four types of Autotasks, with each of them supporting a different aspect of the pool operation:

### AutoPay Autotask

* Fetch all credits with a due date in the next 2 days and the credit state is in `GoodStanding` or `Delayed`.
* For each credit, if the borrower has enough funds in their wallet to cover the payment amount (`nextDue + totalPastDue`), and has approved enough allowance to the pool, call `makePayment` on behalf of the borrower to pay back the pool.

### Close Epoch Autotask

* Fetch all pools where the current epoch `endTime` is in the past.
* Call `processYieldForLenders` on the junior and senior tranche.
* Call `closeEpoch` on the epoch manager contract.
* Call `investFeesInFirstLossCover` on the pool fee manager contract.
* Call `payoutYield` on all first loss cover contracts of the pool.

### Refresh Credit Autotask

* Fetch all credit lines where `nextBillRefreshDate` is in the past and credit state is in `GoodStanding` or `Delayed`.
* Call `refreshCredit` on the credit manager contract for that borrower.

### Start Committed Credit Autotask

* Fetch all credit lines where credit state is `Approved`, committed amount is greater than 0, and the designated credit start date is in the past.
* Call `startCommittedCredit` on the credit manager contract for that credit.

### Submit Redemption Request Autotask

* Fetch all pools that has the `autoRedmeptionAfterLockUp` setting enabled.
* For each pool, fetch all lenders whose deposit lockup period has expired.
* Call `addRedemptionRequest` on the contract to submit redemption requests for all the shares owned by the lender.

Unless otherwise noted, all Autotasks run every 5 minutes. For access control, Autotasks will call contracts using the Sentinel service account wallet.
