Solution Overview

Problem

Users face inconvenience when managing multiple wallets for blockchain-based metaverse and Web 3.0 services, particularly due to the complexity of switching between custodial and non-custodial wallets and managing NFTs across these platforms.

Innovation Solution

An information processing system that records and correlates address information of multiple wallets, allowing seamless switching and management between custodial and non-custodial wallets, enabling unified display and transfer of NFTs and crypto assets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users manage multiple wallets separately for different services, then security and service specialization are improved, but user convenience and operational complexity deteriorate

Engineering Contradiction:

Improvewallet securityVSAvoidwallet switching convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple separate wallets (custodial and non-custodial) into a unified wallet management system. The system correlates address information across different wallets and provides a single interface for managing all wallets, allowing users to switch between them seamlessly while maintaining the security characteristics of each wallet type.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The wallet management system is designed to handle multiple wallet types (custodial and non-custodial) and multiple blockchain networks through a single unified interface. The system correlates address information across different wallets and provides universal functionality for managing diverse wallet types without requiring separate management systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If users selectively use multiple wallets for different services, then service optimization is improved, but system complexity and management difficulty worsen

Engineering Contradiction:

Improveservice optimizationVSAvoidwallet management complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments wallet management by correlating address information across different wallets while maintaining their individual characteristics. The system divides wallet management into correlated address groups, allowing users to select specific wallets for specific services while the system handles the complexity of managing multiple wallets through centralized correlation.

Inventive Principle:

Principle #1Segmentation

3Loss of information

If NFT information is managed across multiple wallets, then asset visibility is improved, but data management complexity worsens

Engineering Contradiction:

ImproveNFT asset visibilityVSAvoiddata management complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent merges NFT information from multiple correlated wallets into a unified view. The system correlates address information across wallets and aggregates NFT holdings, allowing users to see all their NFT assets in one place while the system automatically handles the complexity of querying and managing data across multiple wallet addresses.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An information processing device includes a recording unit that records address information of a plurality of wallets of a user including a custodial wallet and a non-custodial wallet in correlation with each other; and a control unit that switches, based on the address information, the wallet to be used among the plurality of wallets according to an operation by the user. The present technology can be applied to an information processing system.
