UXLINK supports Ethereum EIP-7702 upgrade, launching two core smart contracts

On August 13, 2025, a leading AI-driven Web3 social infrastructure platform announced its support for Ethereum's latest revolutionary upgrade EIP-7702, and simultaneously launched two core Solidity smart contracts: UX7702Delegator and UX7702ValidatorProxy. This technological implementation will greatly enhance the efficiency and security of user interactions on the chain, injecting new energy into the Web3 social ecosystem and marking a new phase in the industry regarding account abstraction and smart contract interactions.

In the context of the rapid development of the Web3 ecosystem, the efficiency, security, and scalability of on-chain interactions are becoming key factors driving the next wave of industry explosion. The introduction of EIP-7702 signifies that Ethereum is moving towards a more flexible, scalable, and user experience-centered interaction model. As a pioneer in the social infrastructure track, this platform is proving through practical actions that the deep integration of technology and ecology can bring a qualitative leap to the industry.

Dual-core architecture: The collaboration between Delegator and ValidatorProxy

The UX7702 Delegator, as a core contract proxy, aims to minimize the number of interaction steps between users and the blockchain. By supporting batch calls to multiple smart contracts 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 signed information is immutable and easily verifiable, adding the first layer of security for interactions.
• Atomic multi-operation execution: During the execution process, if any operation fails, the system can automatically roll back entirely to ensure the consistency of the on-chain state.
• ERC-1271 compatibility: grants cross-standard integration capabilities, facilitating collaboration with more signature verification models.

The UX7702ValidatorProxy serves as the core defense line, acting as the hub for signature verification and permissions management.

• Pluggable verification module: not only supports existing algorithms but also reserves interfaces for future integration of advanced signature algorithms such as BLS and Schnorr.
• Multi-dimensional Nonce system: Break away from the limitations of traditional single-increment Nonce, supporting concurrent transactions without sacrificing security.
• On-chain + off-chain dual verification: Combining real-time metadata validity checks to prevent malicious calls and the introduction of abnormal data.

This "dual-engine" architecture not only ensures operational efficiency but also strengthens security from the source, providing developers and users with a solid infrastructure guarantee.

Technological Breakthroughs and Security Defenses

In the process of implementing EIP-7702, the platform has overcome several core challenges:

1. Secure isolation for batch execution: Relying on the atomicity of EVM transactions, ensuring a full chain rollback in case of any call failure.
2. Composite signatures and permission hierarchy: Achieve multi-level signatures and authorization delegation through a flexible permission model to meet the needs of enterprise-level and high-security scenarios.
3. AI-driven real-time security audit: Introducing the third-party ChainSpecter AI audit tool, which conducts both static and dynamic dual detection on the 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 rather a continuous online intelligent defense system. Its machine learning model can constantly update protection strategies and provide real-time responses to the latest attack methods, which means that developers no longer need to worry about the risk exposure caused by security delays.

The Co-evolution of EIP-7702 and EIP-4337

The platform does not view EIP-7702 as a standalone technical node, but rather integrates it into the overall evolution path of account abstraction.

Traditional EOA → EIP-4337 account abstraction → EIP-7702 smart contracts

This design allows users to enjoy a faster, safer, and more flexible on-chain experience without having to learn obscure new rules or migrate accounts or assets when upgrading their experience.

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: Trade batching and Gas fee sponsorship make complex on-chain interactions as smooth as Web2 applications.
• Ecological compatibility: Fully compatible with account abstraction protocols such as EIP-4337, providing underlying support for a diverse decentralized application ecosystem.
• Security Confidence: AI auditing reduces contract risks and enhances long-term trust between developers and users.

The platform firmly believes that the evolution of infrastructure is the core driving force pushing the industry forward. In today's context, where decentralization, AI integration, and cross-chain interoperability are gradually becoming industry consensus, they are not just creating a toolkit but laying the foundation for the future of Web3 social civilization. The team stated: "This is not just a technological upgrade, but a gathering of industry confidence. We see a more open, intelligent, and secure Web3 world taking shape, and this time, we will work with all builders to make it a reality."

Open Source and Global Collaboration

The platform has open-sourced all EIP-7702 contract code to GitHub 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 the shortcomings of blockchain development, but rather its strongest moat.
