## SafeMath Patterns

SafeMath patterns are specific coding conventions that wrap arithmetic operations in functions that check for overflow and underflow, reverting the transaction if an error is detected. By using these patterns, developers ensure that math operations are always safe and predictable, preventing common exploits that could otherwise drain a protocol's funds.

These patterns typically involve checking the inputs and outputs of operations against the bounds of the integer type being used. While newer versions of the Solidity compiler include built-in overflow checks, understanding and implementing these patterns remains important for legacy code and complex financial logic that requires custom handling.

The widespread adoption of SafeMath has been a major contributor to the security of the Ethereum ecosystem, demonstrating the power of simple, standardized defensive coding patterns to protect complex financial systems from common arithmetic-based attacks.
