Abstract

This specification defines the minimum interface required to identify an account that controls a contract.

Motivation

This is a slimmed-down alternative to EIP-173.

Specification

The key word “MUST” in this document is to be interpreted as described in RFC 2119.

Every contract compliant with this EIP MUST implement the EIP5313 interface.

// SPDX-License-Identifier: CC0-1.0
pragma solidity ^0.8.15;

/// @title EIP-5313 Light Contract Ownership Standard
interface EIP5313 {
    /// @notice Get the address of the owner
    /// @return The address of the owner
    function owner() view external returns(address);
}

Rationale

Key factors influencing the standard:

Minimize the number of functions in the interface
Backwards compatibility with existing contracts

This standard can be (and has been) extended by other standards to add additional ownership functionality. The smaller scope of this specification allows more and more straightforward ownership implementations, see limitations explained in EIP-173 under “other schemes that were considered”.

Implementing EIP-165 could be a valuable addition to this interface specification. However, this EIP is being written to codify existing protocols that connect contracts (often NFTs), with third-party websites (often a well-known NFT marketplace).

向后兼容性

Every contract that implements EIP-173 already implements this specification.

Security Considerations

Because this specification does not extend EIP-165, calling this EIP’s owner function cannot result in complete certainty that the result is indeed the owner. For example, another function with the same function signature may return some value that is then interpreted to be the true owner. If this EIP is used solely to identify if an account is the owner of a contract, then the impact of this risk is minimized. But if the interrogator is, for example, sending a valuable NFT to the identified owner of any contract on the network, then the risk is heightened.
