On August 13, 2025, the globally leading AI-driven Web3 social infrastructure platform UXLINK announced its support for Ethereum's latest revolutionary upgrade—EIP-7702—and simultaneously launched two core Solidity smart contracts: UX7702Delegator and UX7702ValidatorProxy. This milestone in technology not only greatly enhances the efficiency and security of user interactions on-chain but also injects new energy into the entire Web3 social ecosystem, marking a new chapter in the industry regarding account abstraction and smart contract interactions.
In the context of the rapid evolution of the global Web3 ecosystem, the efficiency, security, and scalability of on-chain interactions are becoming key factors driving the next wave of industry explosion. The launch of EIP-7702 signifies that Ethereum is moving towards a more flexible, scalable, and user experience-centric interaction model, while UXLINK, as a pioneer in the social infrastructure space, is demonstrating through practical actions that the deep integration of technology and ecology can bring a qualitative leap to the industry.
Dual Core Architecture: The Synergy of Delegator and ValidatorProxy
UX7702Delegator, as the core contract proxy, aims to minimize the interaction steps between users and the blockchain. By supporting batch calls to multiple smart contract instructions, it not only reduces Gas costs but also makes complex on-chain operations as simple as "one-click execution."
EIP-712 structured data signature: Ensures that the signature information is tamper-proof and easy to verify, adding the first layer of security to interactions.
Atomic multi-operation execution: During execution, if any operation fails, the system can automatically roll back entirely, ensuring the consistency of on-chain states.
ERC-1271 compatibility: Grants cross-standard integration capabilities, facilitating collaboration with more signature verification models.
UX7702ValidatorProxy serves as the core defense line, acting as the hub for signature verification and permission management.
Pluggable verification modules: Not only supports existing algorithms but also reserves interfaces for future integration of advanced signature algorithms like BLS and Schnorr.
Multi-dimensional Nonce system: Breaks free from the limitations of traditional single-increment Nonce, supporting concurrent transactions without sacrificing security.
On-chain + off-chain dual verification: Combines real-time metadata validity checks to prevent malicious calls and abnormal data input.
This "dual-engine" architecture ensures both operational efficiency and strengthens security from the ground up, providing a solid infrastructure guarantee for developers and users.
Technical Breakthroughs and Security Defense
In the process of implementing EIP-7702, UXLINK has overcome several core challenges:
Security isolation for batch execution: Leveraging EVM transaction atomicity to ensure a full chain rollback in case of any call failure.
Composite signatures and permission layering: Achieving multi-level signatures and authorization delegation through a flexible permission model, meeting the needs of enterprise-level and high-security scenarios.
AI-driven real-time security auditing: Introducing the third-party ChainSpecter AI auditing tool for static and dynamic dual detection of contracts deployed on Arbitrum One, identifying and marking potential security risks in real-time.
It is worth mentioning that AI auditing is not a one-time security check but a continuously online intelligent defense system. Its machine learning model can continuously update protection strategies and provide real-time responses to the latest attack methods, meaning developers no longer need to worry about risk exposure due to security delays.
The Co-evolution of EIP-7702 and EIP-4337
UXLINK does not view EIP-7702 as a standalone technical node but integrates it into the overall evolution path of account abstraction:
Traditional EOA → EIP-4337 account abstraction → EIP-7702 smart contractization
This design allows users to enjoy a faster, safer, and more flexible on-chain experience without needing to learn obscure new rules or migrate accounts or assets during the upgrade.
Industry Significance and Future Outlook
The implementation of EIP-7702 represents not only a technical upgrade for the entire Web3 industry but also a dual leap in user experience and ecological value:
Ultimate experience: Transaction batch processing and Gas fee sponsorship make complex on-chain interactions as smooth as Web2 applications.
Ecological compatibility: Fully compatible with account abstraction protocols like EIP-4337, providing underlying support for a diverse decentralized application ecosystem.
Security confidence: AI auditing reduces contract risks, enhancing long-term trust for developers and users.
UXLINK firmly believes that the evolution of infrastructure is the core driving force for advancing the industry. As decentralization, AI integration, and cross-chain interoperability gradually become industry consensus, UXLINK is not only building a toolkit but also laying the foundation for the future of Web3 social civilization. "This is not just a technological upgrade; it is a gathering of industry confidence," the UXLINK team stated. "We see a more open, intelligent, and secure Web3 world taking shape, and this time, UXLINK will work with all builders to make it a reality."
Open Source and Global Collaboration
UXLINK has open-sourced all EIP-7702 contract codes on GitHub(https://github.com/UXLINK/uxlink/tree/master/contracts/EIP-7702) and extends a sincere invitation to developers worldwide: review the code, submit contributions, and co-create the ecosystem. In the future, the team will continue to promote the deep integration of AI security tools and Web3 infrastructure, ensuring that security and efficiency are no longer weaknesses in blockchain development but become its strongest moat.
