StopError

Represents a contract/bytecode error that occurs when a STOP operation is executed.

Stop errors can occur due to:

  • The contract execution reaching a STOP opcode.

To debug a stop error:

  1. Review Contract Logic: Ensure that the STOP opcode is used intentionally and correctly.
  2. Use TEVM Tracing: Utilize TEVM tracing to step through the contract execution and identify the STOP operation.

Example

import { StopError } from '@tevm/errors'
try {
// Some operation that can throw a StopError
} catch (error) {
if (error instanceof StopError) {
console.error(error.message);
// Handle the stop error
}
}

Param

A human-readable error message.

Param

Additional parameters for the BaseError.
