As indicated on the audit description, users intending to mint/redeem a large amount will need to mint/redeem over several blocks due to maxMintPerBlock or maxRedeemPerBlock. However, these RFQs are prone to DoS because mintedPerBlock[block.number] + mintAmount > maxMintPerBlock or redeemedPerBlock[block.number] + redeemAmount > maxRedeemPerBlock could revert by only 1 wei in excess.
While these issues could be sorted by the backend to make a full use of maxMintPerBlock or maxRedeemPerBlock per block, it will make the intended logic a lot more efficient by auto reducing the RFQ amount to perfectly fill up the remaining quota for the current block. Better yet, set up a queue system where request amount running in hundreds of thousands or millions may be auto split up with multiple orders via only one signature for batching.
