  You can use the `std::stol` function in C++ to convert a string to a long int for cryptocurrency transactions. Here's an example: ```cpp #include <iostream> #include <string> int main() { std::string str = "1234567890"; long int convertedValue = std::stol(str); std::cout << "Converted value: " << convertedValue << std::endl; return 0; } ``` This code snippet uses the `std::stol` function to convert the string to a long int. Make sure to include the necessary headers (`<iostream>`, `<string>`) and modify the `str` variable with your actual string value. If the string cannot be converted to a long int, an exception of type `std::invalid_argument` or `std::out_of_range` will be thrown. Feel free to ask if you have any more questions!
