## Preamble
EIP: 141
Title: Designated invalid EVM instruction
Author: Alex Beregszaszi
Type: Standard Track
Category: Core
Status: Accepted
Created: 2017-02-09
## Abstract
An instruction is designated to remain as an invalid instruction.
## Motivation
The invalid instruction can be used as a distinct reason to abort execution.
## Specification
The opcode `0xfe` is the `INVALID` instruction. It can be used to abort the execution (i.e. duplicates as an `ABORT` instruction).
## Backwards Compatibility
This instruction was never used and therefore has no effect on past contracts.
