---
> ### redeemCollateral
Send _ZUSDamount ZUSD to the system and redeem the corresponding amount of collateral from as many Troves as are needed to fill the redemption
request. Applies pending rewards to a Trove before reducing its debt and coll.
Note that if _amount is very large, this function can run out of gas, specially if traversed troves are small. This can be easily avoided by
splitting the total _amount in appropriate chunks and calling the function multiple times.
Param `_maxIterations` can also be provided, so the loop through Troves is capped (if it’s zero, it will be ignored).This makes it easier to
avoid OOG for the frontend, as only knowing approximately the average cost of an iteration is enough, without needing to know the “topology”
of the trove list. It also avoids the need to set the cap in stone in the contract, nor doing gas calculations, as both gas price and opcode
costs can vary.
All Troves that are redeemed from -- with the likely exception of the last one -- will end up with no debt left, therefore they will be closed.
If the last Trove does have some remaining debt, it has a finite ICR, and the reinsertion could be anywhere in the list, therefore it requires a hint.
A frontend should use getRedemptionHints() to calculate what the ICR of this Trove will be after redemption, and pass a hint for its position
in the sortedTroves list along with the ICR value that the hint was found for.
If another transaction modifies the list between calling getRedemptionHints() and passing the hints to redeemCollateral(), it
is very likely that the last (partially) redeemed Trove would end up with a different ICR than what the hint is for. In this case the
redemption will stop after the last completely redeemed Trove and the sender will keep the remaining ZUSD amount, which they can attempt
to redeem later.
```solidity
function redeemCollateral(uint256 _ZUSDAmount, address _firstRedemptionHint, address _upperPartialRedemptionHint, address _lowerPartialRedemptionHint, uint256 _partialRedemptionHintNICR, uint256 _maxIterations, uint256 _maxFee) external nonpayable
