         Abstract
      
      
    


This EIP adds a new ERC-4804 resolveMode to resolve ERC-5219 contract resource requests.

  
    
      
      
         Specification
      
      
    


The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “NOT RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC 2119 and RFC 8174.


Contracts wishing to use ERC-5219 as their ERC-4804 resolve mode must implement the following interface:


/// @dev IDecentralizedApp is the ERC-5219 interface
interface IERC5219Resolver is IDecentralizedApp {
    // @notice The ERC-4804 resolve mode
    // @dev    This MUST return "5219" (0x3532313900000000000000000000000000000000000000000000000000000000) for ERC-5219 resolution (case-insensitive). The other options, as of writing this, are "auto" for automatic resolution, or "manual" for manual resolution.
    function resolveMode() external pure returns (bytes32 mode);
}




  
    
      
      
         Rationale
      
      
    


ERC-165 was not used because interoperability can be checked by calling resolveMode.

  
    
      
      
         Backwards Compatibility
      
      
    


No backward compatibility issues found.

  
    
      
      
         Reference Implementation
      
      
    


abstract contract ERC5219Resolver is IDecentralizedApp {
    function resolveMode() public pure returns (bytes32 mode) {
      return "5219";
    }
}




  
    
      
      
         Security Considerations
      
      
    


The security considerations of ERC-4804 and ERC-5219 apply.
