On August 13, 2025, the world-leading AI-driven Web3 social infrastructure platform UXLINK announced its support for Ethereum's latest revolutionary upgrade—EIP-7702, simultaneously launching two core Solidity smart contracts: UX7702Delegator and UX7702ValidatorProxy. This milestone technological implementation not only greatly enhances user interaction efficiency and security on-chain but also injects new energy into the entire Web3 social ecosystem, marking the industry’s entry into a new chapter in account abstraction and smart contract interaction.
Against the backdrop 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 track, is proving through practical actions that the deep integration of technology and ecology can bring qualitative leaps to the industry.
Dual-core architecture: collaborative operation of Delegator and ValidatorProxy
UX7702Delegator acts as the core contract proxy, aiming to minimize the steps users take to interact with 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 signatures: ensure that signature information is tamper-proof and easy to verify, adding the first lock for interaction security.
Atomic multi-operation execution: during execution, if any operation fails, the system can automatically roll back as a whole, ensuring the consistency of on-chain state.
ERC-1271 compatibility: endows it with cross-standard integration capabilities, facilitating collaboration with more signature verification models.
UX7702ValidatorProxy serves as the core line of defense, acting as the hub for signature verification and permission management.
Pluggable verification module: supports existing algorithms and reserves interfaces for future integration of advanced signature algorithms such as BLS and Schnorr.
Multi-dimensional Nonce system: breaking free 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 abnormal data input.
This 'dual-engine' architecture ensures operational efficiency while strengthening security from the source, providing a solid infrastructure guarantee for developers and users.
Technological breakthroughs and security defenses
In the process of implementing EIP-7702, UXLINK has overcome several core challenges:
Security isolation for batch execution: relying on EVM transaction atomicity to ensure a full chain rollback in case of any call failure.
Composite signatures and permission layering: through a flexible permission model, realize multi-level signatures and authorization delegation to meet 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, to identify and mark 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.
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 when upgrading their experience.
Industry significance and future outlook
The implementation of EIP-7702 represents not only a technological upgrade for the entire Web3 industry but also a dual leap in user experience and ecological value:
Ultimate experience: transaction batching and Gas fee sponsorship make complex on-chain interactions as smooth as Web2 applications.
Ecological compatibility: fully compatible with EIP-4337 and other account abstraction protocols, 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.
UXLINK firmly believes that the evolution of infrastructure is the core driving force that propels the industry forward. In an era where decentralization, AI integration, and cross-chain interoperability are gradually becoming industry consensus, UXLINK is not only creating a toolkit but also laying the foundation for the future of Web3 social civilization. 'This is not just a technological upgrade, but 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 code on GitHub (https://github.com/UXLINK/uxlink/tree/master/contracts/EIP-7702) and extends a sincere invitation to global developers: 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 become its strongest moat.
