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:

Review Contract Logic: Ensure that your smart contract logic correctly handles stack operations, especially in loops and conditional branches.
Use TEVM Tracing: Utilize TEVM tracing to step through the transaction and inspect stack changes.
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.
