[0025] Figure 1 It is a schematic structural diagram of the cross-border payment system based on Web3.0 and RWA tokenization of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1 , a cross-border payment system based on Web3.0 and RWA tokenization in this embodiment includes an RWA tokenization module, a smart contract automated cross-border transaction module, a multi-chain communication module, a privacy protection module, a dynamic asset evaluation and risk management module, and a data analysis module:

[0028] The RWA tokenization module includes the collection, verification, mapping, on-chain, and token generation of asset information, and uses non-fungible token or divisible fungible token technology to select the optimal token model according to the asset type;

[0029] The smart contract automated cross-border transaction module includes asset listing, transaction matching, clearing, delivery, and settlement, sets a condition trigger mechanism, and integrates trade compliance checks and payment gateway interfaces;

[0030] The multi-chain communication module constructs a cross-chain communication protocol, allows asset transfer and status synchronization between different blockchains, ensures the compatibility and liquidity of tokens through a standardized token format, and realizes the seamless exchange of multi-chain assets;

[0031] The privacy protection module uses zero-knowledge proof algorithms to verify the authenticity of assets and transaction compliance during the transaction process, while protecting the privacy of participating parties, and designs an anonymization scheme to hide transaction details;

[0032] The dynamic asset evaluation and risk management module is based on Web3.0 real-time data collection and analysis, dynamically calculates the current value of RWA, introduces a machine learning model to evaluate the asset risk level, conducts predictive analysis on the asset value in combination with market fluctuations, dynamically adjusts the tokenized value of the asset, and enhances the flexibility and accuracy of cross-border trade transactions;

[0033] The data analysis module is used to analyze and process the background data, and issue an alarm when abnormal data appears to ensure the stability of the system operation.

[0034] In this embodiment, the tokenization of RWA includes the collection, verification, mapping, on-chain and token generation of asset information. Using non-fungible token (NFT) or divisible fungible token (FT) technology, the optimal token model is selected according to the asset type. An on-chain asset registration system is introduced to record the ownership, evaluated value and status update mechanism corresponding to RWA. It provides an efficient and standardized RWA tokenization process to ensure data authenticity and prevent double registration. It supports dynamic updating of asset status (such as ownership change, value fluctuation, etc.) and automatically triggers the execution of smart contracts.

[0035] In this embodiment, the smart contract automates cross-border transactions. Based on the smart contract, an automated cross-border transaction process is designed, including asset listing, transaction matching, clearing, delivery and settlement. Set a condition trigger mechanism: automatically update the token ownership after the payment is completed. Incorporate trade compliance checks (such as customs duties) and payment gateway interfaces, and support multiple payment methods (fiat currency, cryptocurrency). Write all key nodes of cross-border trade into the smart contract to reduce human intervention and improve transaction efficiency and transparency.

[0036] In this embodiment, multi-chain interoperability supports the construction of cross-chain communication protocols (such as based on cross-chain bridges or multi-chain aggregators), allowing asset transfer and status synchronization between different blockchains. Ensure the compatibility and liquidity of tokens through standardized token formats (such as ERC-20, ERC-721). Achieve seamless exchange of multi-chain assets, break through the technical limitations of a single chain, and support multi-currency payment and asset transfer in cross-border trade.

[0037] In this embodiment, the privacy protection mechanism based on zero-knowledge proof uses the zero-knowledge proof (ZKP) algorithm to verify the authenticity of assets and transaction compliance during the transaction process, while protecting the privacy of the participating parties. Design an anonymization scheme that hides transaction details (such as price, asset value) to ensure that trade participants only disclose necessary information. Ensure the balance between privacy and compliance, reduce the risk of information leakage, and meet the sensitive needs of multi-party participation in cross-border trade.

[0038] In this embodiment, the dynamic asset evaluation and risk management model dynamically calculates the current value of RWA based on Web3.0 real-time data collection and analysis (such as market data on the blockchain and data from IoT devices). A machine learning model is introduced to evaluate the asset risk level, and predictive analysis of asset value is conducted in combination with market fluctuations. The tokenized value of the asset is dynamically adjusted to enhance the flexibility and accuracy of cross-border trade transactions.

[0039] In the selection of the blockchain, a suitable blockchain platform such as Ethereum, Hyperledger Fabric, etc. should be chosen as the underlying architecture of the system. And smart contracts are designed and implemented to automate the payment process and execute business logic.

[0040] In the design of security, the latest network security measures such as DDoS protection and intrusion detection systems are adopted to resist potential cyberattacks. Ensure that all transaction data is protected by strong encryption algorithms.

[0041] In the design of the user interface and experience, an intuitive and easy-to-use user interface is designed to ensure that users can easily perform cross-border payment operations. Reduce operation complexity and improve user satisfaction.

[0042] In system integration and compatibility, API interfaces are developed so that the system can be integrated with existing banking systems, payment gateways, and other financial service providers. Ensure that the system can run on different devices and operating systems, including mobile devices and desktop computers.

[0043] In terms of performance and scalability, the performance of the system under high load should be evaluated to ensure that the system still runs stably when the transaction volume surges. The system architecture also needs to be designed to support future expansion, including adding new payment channels and currency types.

[0044] In deployment and maintenance, the system is deployed in a secure environment to ensure that all backup and recovery mechanisms are in place, and a system maintenance plan is established to implement regular updates, security patch applications, and performance monitoring.

[0045] In risk management and compliance, identify the risks that the system may face, formulate corresponding risk mitigation strategies, and continuously monitor the system to ensure that it complies with all relevant legal and regulatory requirements.

[0046] Through these comprehensive research and analyses, the system design and development will ensure that the cross-border payment system meets high standards in terms of technology, security, user experience, and compliance, providing users with a reliable, efficient, and secure payment solution.

[0047] In summary, the cross-border payment system based on Web3.0 and RWA tokenization combines RWA technology and Web3.0 to achieve decentralized management of assets and improve the transparency of the entire financial system. The application of blockchain technology ensures the immutability of transaction records, making the ownership and transfer history of assets traceable and auditable, thus enhancing market trust and efficiency. Through RWA technology, the tokenization of physical assets reduces the participation of traditional financial intermediaries, thereby reducing transaction and management costs. At the same time, the use of Web3.0's automated smart contracts reduces the settlement time of transactions and improves the efficiency of capital flow, making cross-border payments and asset transfers faster and more economical. The Web3.0 architecture provides stronger data security and privacy protection on blockchain technology. It gives users full control over their data and reduces the risk of data leakage and abuse. In addition, decentralization enhances the overall security of the system.
