NFT Avatar Item Attachment via Blockchain Smart Contracts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In many metaverses, avatars and items are limited to a specific metaverse and cannot be used across different platforms, even if they are NFTed. Additionally, items purchased in one metaverse are not transferable to another, requiring separate management.
Innovation Solution
A method and system for processing the attachment and removal of items for an NFT model, utilizing smart contracts on a blockchain to enable the try-on and removal of items across different metaverses, allowing users to decide which items to attach or detach from their NFT avatars and execute transactions accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If items and costumes are managed separately from avatars in each metaverse, then each metaverse can maintain its own item management system, but items cannot be distributed on the blockchain along with avatars and cannot be used across different metaverses
Solution Approach 1:
The patent combines avatar data and item data into a single NFT structure, where items are stored as metadata within the avatar NFT. This merging allows items to be automatically distributed on the blockchain along with the avatar, enabling cross-metaverse usability while simplifying the management structure from separate systems to an integrated one.
Solution Approach 2:
The patent creates a universal NFT structure that can function across multiple metaverses. The avatar NFT with embedded item metadata serves as a universal credential that can be recognized and used in different metaverse environments, eliminating the need for separate item management systems in each metaverse.
2Reliability
If avatars are NFTed with separate item management, then avatars can be traded on blockchain marketplaces, but items purchased in one metaverse remain confined to that metaverse
Solution Approach 1:
By merging item data into the avatar NFT's metadata, the patent ensures that when an avatar NFT is traded on blockchain marketplaces, the associated items are automatically transferred along with it. This eliminates the confinement of items to a single metaverse while maintaining reliable blockchain-based ownership verification.
3Ease of operation
If items are attached to avatars through separate management systems, then each metaverse can control its own item economy, but users must manage items separately in each metaverse
Solution Approach 1:
The patent merges item management into the avatar NFT structure, allowing users to manage all their items through a single avatar NFT rather than maintaining separate item inventories in each metaverse. This significantly reduces the time and effort required for item management while maintaining metaverse-specific economic controls through the metadata structure.

AI summary
Providing an NFTed avatar that may be used across different metaverses and may be dressed up with different items. There is provided a method for processing dress-up of an NFTed avatar by a computer, and the method comprises the steps of: referencing, by the computer, a smart contract for the avatar and data for displaying the avatar, and displaying the avatar to a user; referencing, by the computer, a smart contract for items and data for displaying the items, and displaying the items to a user; providing the user, by the computer, with a try-on interface for trying items on the avatar; providing the user, by the computer, with an interface for allowing the user to decide items to attach to the avatar; and executing, by the computer, based on the user's decision on items to be attached on the avatar, a writing on the blockchain for associating item NFTs with an avatar NFT for the smart contract for the avatar.
