Rounding Error Risks

Rounding error risks arise whenever division or scaling operations are performed in a system with limited precision. In financial derivatives, even a small rounding error can be exploited if it consistently favors one party over another.

For instance, if a protocol rounds down the amount of collateral required, it might allow users to take on more leverage than they should, increasing the risk of insolvency. Developers must decide whether to round up or down based on the specific context ⎊ often choosing the side that protects the protocol's treasury.

These risks are subtle and often overlooked in initial development, making them a prime target for sophisticated attackers. Rigorous unit testing and mathematical modeling are required to quantify and mitigate these risks, ensuring that the protocol's economic design remains sound.
