         Simple Summary
      
      
    

Specify an Ethereum address range occupied by precompiles and future system contracts. Regular accounts and contracts cannot obtain such an address.

  
    
      
      
         Abstract
      
      
    

The address range between 0x0000000000000000000000000000000000000000 and 0x000000000000000000000000000000000000ffff is reserved for precompiles and system contracts.

  
    
      
      
         Motivation
      
      
    

This will simplify certain future features where unless this is implemented, several exceptions must be specified.

  
    
      
      
         Specification
      
      
    

The address range between 0x0000000000000000000000000000000000000000 and 0x000000000000000000000000000000000000ffff is reserved for precompiles and system contracts.


Due to the extremely low probability (and lack of adequate testing possibilities) no explicit checks should be added to ensure that external transaction signing or
the invoking of the CREATE instruction can result in a precompile address.

  
    
      
      
         Rationale
      
      
    

N/A

  
    
      
      
         Backwards Compatibility
      
      
    

No contracts on the main network have been created at the specified addresses. As a result it should pose no backwards compatibility problems.
