StackUnderflowError

Represents a contract/bytecode error that occurs when there is a stack underflow during execution. This error is typically encountered when an operation requires more stack items than are present.

Stack underflow errors can occur due to:

  • Incorrect management of stack operations (e.g., popping more items than available).
  • Bugs in smart contract logic leading to unexpected stack behavior.
  • Issues with function calls that manipulate the stack incorrectly.

To debug a stack underflow error:

  1. Review Contract Logic: Ensure that your smart contract logic correctly handles stack operations, especially in loops and conditional branches.
  2. Use TEVM Tracing: Utilize TEVM tracing to step through the transaction and inspect stack changes.
  3. Use Other Tools: Use other tools with tracing such as Foundry.
  • Ethereumjs Source: Refer to the source file where this error can occur.

Example

try {
// Some operation that can throw a StackUnderflowError
} catch (error) {
if (error instanceof StackUnderflowError) {
console.error(error.message);
// Handle the stack underflow error
}
}

Param

A human-readable error message.

Param

Additional parameters for the BaseError.
