Recursive Function Optimization

Recursive function optimization is the process of refactoring code to eliminate or limit recursion to prevent stack overflows and minimize gas usage. Since the EVM has a strict stack limit, deep recursion is often replaced with iterative loops that maintain state in memory or storage.

This is particularly important in DeFi protocols where pricing algorithms or tree-based data structures might otherwise hit the 1024 limit. By converting recursive calls to loops, developers improve the predictability and security of their financial contracts.

This practice is a fundamental skill in writing robust, gas-efficient smart contracts that can handle complex market data.
