ERC-6551 details a proposal outlining the specifications and rationale for a system that aims to enhance the capabilities of NFTs by giving them the same rights as Ethereum user accounts. It proposes a singleton registry for token-bound accounts and a common interface for their implementations.
The proposal introduces a system with several key components:
1. Singleton Registry: Acts as the entry point for token-bound account address queries, allowing for the creation and computation of these accounts.
2. Account Interface: Defines the essential functions that token-bound accounts should implement, such as receiving Ether, providing information about the associated NFT, maintaining state, and validating signers.
3. Execution Interface: Specifies an optional interface for executing operations on behalf of the token-bound account. It includes functions to execute low-level operations like CALL, DELEGATECALL, CREATE, and CREATE2.
The proposal also discusses the rationale behind its design choices, such as using ERC-1167 minimal proxies for account deployment, enabling counterfactual accounts, trustless deployments, cross-chain compatibility, and more. Additionally, it addresses considerations regarding fraud prevention, ownership cycles, and copyright.
Overall, this proposal seeks to empower NFTs by allowing them to have the same rights as Ethereum user accounts, enabling complex real-world assets to be represented as NFTs using a standardized pattern.
