When writing smart contracts, the stack too deep Solidity error is a common problem you will find. The “stack too deep” error in Solidity typically occurs when a contract calls itself recursively or calls another contract in an infinite loop.
The call stack in Ethereum has a limited depth, and if the stack exceeds the maximum depth, the contract will throw an exception and execution will be halted. The maximum depth of the call stack is around 1024.
Here’s an example of how this error can occur:
pragma solidity ^0.4.24;
contract StackOverflow {
function recurse() public {
recurse();
}
}In this contract, the recurse() function calls itself indefinitely, causing the call stack to grow indefinitely until it exceeds the maximum depth. To fix this error, you can try to refactor your code to avoid infinite recursion or infinite loops.
