## Stack Overflow

A stack overflow occurs when a program attempts to use more memory than is allocated for its call stack, usually due to excessive recursion or deeply nested function calls. In the EVM, there is a strict limit on the number of stack items allowed, and exceeding this limit causes the transaction to revert.

While this can act as a defensive measure against certain types of attacks, it is also a common source of bugs in complex smart contracts. Developers must be mindful of their function architecture to avoid deep nesting that could lead to overflow.

This is particularly relevant when building complex, multi-step financial logic that involves multiple contract calls. If a function is too complex, it might exceed the stack limit, making it impossible to execute.

This highlights the need for modular, efficient code that keeps the call stack within manageable bounds. Monitoring stack usage is a key part of the testing process, ensuring that the protocol remains robust under all execution scenarios.

It is a technical constraint that directly influences how smart contracts are written and structured.
