Safe Downcasting
In Solidity, downcasting from a larger integer type to a smaller one can be hazardous due to the lack of automatic overflow checks in versions before 0.8.0. This tutorial explains the risks of downcasting, provides an example of a problematic function in older Solidity versions, and offers a solution using a library like SafeCast to ensure safe operations. Even though Solidity 0.8.0 and later versions include built-in overflow checks, using SafeCast can enhance code clarity and safety.
