NFTAs (NFT-as-Account) pallet

A pallet for converting NFTs into smart accounts that can execute transactions. Alternatively, they can change their owner by simply selling a strict NFT token.

Overview

The NFTAAs pallet extends the NFTs pallet functionality by allowing NFTs to act as accounts, enabling:

• NFT to account conversion
• Account-based transaction execution
• Integration with existing NFT features
• Account-based permission management

To use it in your runtime, you need to implement the nfts::Config trait. You also need to configure pallet-nfts and pallet-utility as those are required.

Terminology

• NFT-as-Account (NFTAA): An NFT that has been converted into a smart account, capable of executing transactions.
• Proxy Call: A transaction executed through an NFTAA's generated account address.
• NFT Account: A deterministically generated account address associated with a specific NFT.
• Listed NFTAA: An NFTAA that is currently listed for sale and cannot execute transactions.

Goals

The NFTAs pallet in Substrate is designed to make the following possible:

• Allow NFTs to act as smart accounts with their own addresses
• Enable NFTs to execute transactions through proxy calls
• Maintain compatibility with all standard NFT features like transfers and sales
• Provide secure permission management for NFTAA execution
• Enable deterministic account generation based on NFT identifiers

Interface

Permissionless dispatchables

• mint: Create a new NFTAA by minting an NFT with an associated account.
• proxy_call: Execute a transaction through an NFTAA's account.

Additional Features

The NFTAA pallet inherits all functionality from the base NFTs pallet, including:

• NFT transfers
• Collection management
• Metadata and attribute management
• Trading features
• Burning mechanisms

Unique NFTAA Features

• Deterministic account generation for each NFT
• Transaction execution through NFT accounts
• State management for NFTAA listings
• Permission validation for proxy calls
• Integration with existing NFT marketplace features

Implementation Details

• NFTAAs cannot execute transactions while listed for sale
• Account addresses are generated deterministically based on collection item IDs and parachain ID
• Proxy calls can only be executed by the current owner of the NFTAA
• All standard NFT features remain available for NFTAAs
