## 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.
