Abstract

UXChain is built on Optimistic Rollup, inheriting its scalability and efficiency while introducing a unique innovative solution: a comprehensive social account abstraction and a native cross-chain framework. This simplifies blockchain interactions and enables seamless asset and data flow across multiple chains. With a user-centered design approach, UXChain uses the UXLINK token as a universal gas payment mechanism, allowing developers to build scalable, multi-chain decentralized applications (dApps) with minimal complexity while offering users a seamless, low-barrier blockchain experience.

1. Introduction

The blockchain ecosystem has long faced challenges in user adoption, primarily due to cumbersome interactions, complex wallet management, high transaction costs, and fragmented cross-network user experiences. Current blockchain architectures impose high technical barriers for both developers and end users, significantly hindering the widespread adoption of blockchain technology.

This paper introduces UXChain, a user experience-oriented all-chain solution designed to address these core challenges through two key innovations:

  • OneAccount: A unified account abstraction protocol [1] framework that simplifies user registration and cross-chain [2] interactions.

  • OneGas: A universal gas [3] solution to address the challenges of fragmented cross-chain gas tokens, their non-interoperability, and high cross-chain transaction costs.

UXChain’s modular [4] and cross-chain interoperable architecture [5], combined with Cross-Rollup [6] technology, aims to deliver faster, lower-cost experiences for users on Optimistic Rollup. This enhances liquidity flow and optimizes user experience.

The features described in this paper will undergo thorough testing on the public UXChain Testnet before being deployed to the UXChain Mainnet.

2. Prior Work and Current Challenges

UXLINK has made significant strides in creating an infrastructure that lowers the barriers to blockchain adoption for large-scale user bases. Its Social Growth Layer [7] has brought notable user growth to blockchain applications. However, several key challenges remain:

  • Complex registration processes: Existing platforms require users to install and manage multiple wallets, understand gas fees, and navigate complicated user interfaces.

  • Poor user experience: Chains are isolated, cross-chain interactions involve high friction, and cross-chain fees are expensive.

  • Development complexity: Developers must manage tedious blockchain-specific logic and become proficient in blockchain-specific programming languages, significantly impacting application development efficiency.

While several existing solutions address some of these issues, they fail to adequately address the challenges of gas fees and the complex interactions across multiple chains. UXChain introduces a new approach to blockchain interaction and user experience to solve these problems.

3. OneAccount Framework

3.1 Simplifying User Registration and Interaction

UXChain introduces the OneAccount framework, an innovative account abstraction protocol enabling users to create smart contract accounts. Key features include:

  • Seamless cross-chain authentication: Single authentication enables access across all chains.

  • Frictionless account experience: Social accounts double as blockchain accounts, eliminating the need for traditional wallet concepts.

  • Social recovery mechanism: Secure and efficient account recovery based on social relationships.

  • Unified cross-network transaction history: Integrated multi-chain data with clear and consolidated transaction records.

In essence, OneAccount significantly reduces the complexity of managing multiple accounts, unifying social and blockchain accounts while enabling seamless login and interaction within dApps.

4. OneGas

4.1 Universal Gas Payment Mechanism

By introducing the UXLINK token as a universal gas payment medium, UXChain redefines the cross-chain transaction fee model:

  • Unified cross-chain gas fee settlement

  • Single-token payment for all on-chain transaction fees

  • Reduced complexity and cost for cross-chain transactions

4.2 Cross-Chain Intent Execution

UXChain implements an innovative cross-chain intent [8] execution system, combining smart routing and path optimization algorithms to parse intents and execute the most optimal on-chain strategies.

By abstracting underlying chain interactions, the system dynamically identifies target chains and token resources, unifying the scheduling and management of cross-chain resources. This shields users from the complexities of specific chains and gas mechanisms.

4.3 Developer-Friendly Framework

Developers are provided with standardized SDKs and modules, simplifying the development of cross-chain applications. This allows developers to focus on core business logic rather than the complexities of underlying blockchain systems.

5. Future Work

Potential future enhancements include:

  • Privacy transactions: Enhancing cross-chain transaction privacy through ZK-Rollup technology.

  • Dynamic intent routing: Selecting the most optimal cross-chain path based on real-time network conditions.

  • Universal trust layer: Establishing a pluggable multi-chain trust and governance framework.

  • Fast settlement network: Introducing a validator network to reduce cross-chain settlement time, offering near real-time liquidity transfers.

  • Secure rollback mechanism: Built-in rollback and cross-chain state validation to ensure asset interaction integrity, enhancing security and efficiency.

6. Conclusion

Through OneAccount and OneGas, UXChain aims to lower the barriers to blockchain adoption. By simplifying user interactions and providing a unified identity and interaction mechanism, UXChain has the potential to become critical infrastructure bridging Web2 and Web3, driving the mass adoption of blockchain technology.
