Solution Overview

Problem

Existing systems fail to maintain a real-time balance of a line of credit for digital transactions, particularly in decentralized finance (DeFi) and traditional finance (TradFi) environments, lacking transparency and security in tokenized credit utilization.

Innovation Solution

A system generates a digital token representing a line of credit, synchronized in real-time, formatted with a smart contract to ensure compliance with payment rules, fraud prevention, and incentives, enabling secure transactions across digital and traditional finance platforms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a line of credit is tokenized for digital transactions, then accessibility to digital assets is improved, but real-time balance maintenance becomes difficult

Engineering Contradiction:
Improveaccessibility to digital assetsVSAvoidreal-time balance maintenance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent introduces a tokenization intermediary layer that bridges traditional line of credit systems and digital asset platforms. The tokenized representation acts as a mediator, enabling digital transactions while maintaining synchronization with the original line of credit balance through smart contract-based accounting mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical balance maintenance systems with automated smart contract-based accounting. The smart contracts automatically track and update balances in real-time, eliminating the need for manual intervention and enabling seamless integration between traditional finance and digital asset environments.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If tokenized line of credit is used for digital transactions, then transaction capability is improved, but security and transparency are compromised

Engineering Contradiction:
Improvetransaction capabilityVSAvoidsecurity and transparency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent replaces traditional centralized security mechanisms with blockchain-based smart contracts. The smart contracts provide transparent, immutable recording of transactions and automatic enforcement of credit terms, enhancing both security and transparency while maintaining full transaction capability.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements real-time feedback mechanisms through smart contracts that automatically monitor transaction conditions and update balances accordingly. This continuous feedback loop ensures transparency and security by providing immediate verification of credit availability and transaction validity.

Inventive Principle:
Principle #23Feedback

3Measurement precision

If real-time synchronization is implemented, then balance accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvebalance accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex manual synchronization systems with automated smart contract-based accounting. The smart contracts automatically maintain real-time balance accuracy through deterministic execution of accounting rules, reducing system complexity while improving measurement precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Disclosed herein are system, method, and computer program product embodiments for tokenization of a line of credit. A method include generating, using at least one processor of an issuer system, a token that represents a line of credit value for a customer account. The method further comprises attaching a smart contract to the token to generate a wrapped token. The smart contract is configured to implement one or more rules associated with the customer account. The method further comprises detecting a trigger event associated with a change in a balance of the line of credit value or the one or more rules and in response to detecting the trigger event, syncing in real-time the wrapped token to the balance of the line of credit value.
