Focus on the rise of social UXLINK One Chain, what innovations and changes will it bring to the industry?

On January 17, UXLINK announced the launch of the first Web3-native social chain, UXLINK ONE Chain, focusing on rise. The Testnet is currently online for developers to apply for to use:

UXLINK ONE is an important part of the Social Growth Layer, built on top of Optimistic Rollup, inheriting its scalability and efficiency, while introducing a unique innovative solution: comprehensive social account abstraction and native cross-chain framework. The mission of UXLINK is to connect Web2 users with the infinite possibilities of Web3, which perfectly aligns with this transformative concept. UXLINK ONE aims to eliminate these barriers through a unified access point, achieving cross-chain interoperability, and allowing Dapps to seamlessly operate in multiple blockchain ecosystems.

This issue will have a conversation with Rolland Saf, the person in charge of the UXLINK ONE project, and Akiya Hiro, to explore what innovations and changes UXLINK One Chain will bring to the industry.

**Q1: As a new generation of blockchain infrastructure, what is the unique positioning of UXLINK One in the combination of SocialFi and Web3 infrastructure? What are your advantages compared to similar projects?

A: The positioning of UXLINK One can be summarized as a "user-oriented chain abstract public chain". We hope to use chain abstraction and account abstraction technology to allow users to easily enjoy the convenience and value brought by Web3 applications without having to pay attention to the underlying complexity.

In the SocialFi scenario, the role of chain abstraction is particularly important, because on-chain social interaction involves high-frequency interaction and incentive mechanisms, which is exactly the bottleneck of traditional blockchain experience.

Compared to similar projects, the biggest difference of UXLINK One is that we are not just a high-performance public chain, but a unified entry point for cross-chain ecology.

We hide complex multi-chain operations at the bottom layer, and users only need one account to complete cross-chain operations without realizing it, using UXLINK Token directly as gas fee. For this purpose, we propose the concept of OAOG Protocol. We have found a balance between user experience and developer friendliness, and provided stronger landing capabilities for SocialFi, PayFi and Dapps.

**Q2: UXLINK One mentioned the implementation of "single account multi-chain support" and "one-click payment"; that is, OAOG (One Account One Gas) Protocol. Behind these technologies, what innovative technology stack have you adopted?

A: In order to achieve these functions, we have made various technological innovations.

First is the account abstraction technology (Account Abstraction), which allows user accounts to no longer be limited to specific public chains, but can operate freely across multiple chains.

Next is the universal payment engine, which supports users to use UXLINK Token as Gas fee. Users only need to use UXLINK Token as the payment fee conversion mechanism, even if the user does not have Gas tokens on the target chain, the transaction can be completed.

In addition, we have adopted an optimized cross-chain communication protocol to ensure the real-time and security of asset and data circulation among multiple chains.

Finally, the L2 framework developed based on the Optimism Stake architecture ensures high performance and low-cost transactions on the chain, while also taking into account the system's scalability and security.

Q3: What is the relationship between UXLINK One and Chain Abstraction?

A: Chain Abstraction can be seen as a bridge between users and the complex underlying layers of the blockchain. Its core idea is to make the diversity of blockchains transparent to users, which means that no matter which chain's application users use, they can achieve seamless operations through UXLINK One.

In the SocialFi scenario, this ability is particularly crucial. For example, when users authorize login, transfer payments, deposit or withdraw funds, interact with NFT purchases in a Dapp, traditional blockchain systems require them to understand a series of complex operations such as wallet management, account address management, network switching, and Gas token management. The introduction of chain abstraction makes these operations "invisible".

Users only need to interact socially as naturally as they do on Web2 platforms, and we handle the underlying cross-chain communication, payment, and settlement. This model not only lowers the user threshold, but also significantly improves the user retention and conversion rates of Dapps.

For Solana ecosystem, ton ecosystem, btc ecosystem, through chain abstraction, let us not only support Ethereum ecosystem projects. All on-chain data will also fall into UXLINK One, which will make the data on the entire chain transparent enough and more secure.

**Q4: How do you view the trade-offs between Optimistic Rollup and zkRollup in terms of performance, scalability, and developer-friendliness? Why did UXLINK ultimately choose the former?

A: From a technical architecture perspective, OPStack provides a proven modular framework. It not only fully compatible with the Ethereum ecosystem but also allows us to customize the underlying logic of the chain according to business needs. This flexibility means that we can create unique functional features while maintaining compatibility.

From the perspective of development efficiency, OPStack has achieved an ideal balance between technical complexity and performance. Compared to the extensive computational resources and complex proof generation process required by the zk-Rollup solution, OPStack is more suitable for our current technical investment. Its architecture is more mature and simple, which can help us quickly launch and verify products, and adapt to the current stage of business requirements.

Currently, the highly anticipated projects Sonic (S), Worldcoin (WLD), and Unichain have all chosen to build on OP Superchain. These successful examples of consumer-oriented applications fully demonstrate the market's recognition of the stability and maturity of OPStack technology.

More importantly, OPStack has reserved ample space for future technological advancements. Its modular design allows us to seamlessly integrate innovative solutions such as ZK technology in the future, ensuring that our technical architecture has the potential for continuous development.

This balance between current demand and future scalability is the ideal choice for our technology selection. It enables us to quickly validate the business model without limiting future technological upgrade paths.

**Q 5: In the blockchain industry, many public chains are designed to be more developer-centric, while UXLINK One chooses to design the architecture of the chain from the perspective of C-end users. What is the reason behind this approach?

A: We always believe that the ultimate value of Web3 technology lies in serving users, rather than just staying in the technology itself. If developers are the core driving force of ecosystem construction, then users are the key to determining whether the entire ecosystem can have long-term sustainable development.

Starting from the design concept of C-end users, we can focus more on solving users' pain points, such as the complexity of multi-chain switching, the opacity of gas fees, and the high entry barriers of operations. We hope to completely change the way users interact with blockchain through chain abstraction technology, so that the user experience of Web3 can truly rival or even surpass Web2.

This user-first approach has also helped us attract more developers who are willing to serve the mass market. These developers can not only build Dapps faster, but also directly benefit from the high conversion rate and long lifecycle brought by the optimization of user experience. They can even make efforts to underdeveloped countries and cities in the payment field, and can bring inclusive finance to more people through web3.

Q 6: Currently, many consumer-facing chains have emerged in the industry, such as Abstraction Chain, etc. What are the differences between UXLINK One and these chains? What are your unique advantages?

A: The biggest difference between UXLINK One and other consumer-oriented chains is that we are not designed for a single scenario, but hope to serve the entire multi-chain ecosystem.

Abstraction Chain and other chains are indeed exploring the direction of account abstraction and user-friendly, but they usually only focus on a particular chain or specific scenario, such as their adoption of ZKStake, which pays more attention to data privacy, while we start from the perspective of the entire chain, creating a truly multi-chain entry point.

Our chain abstraction technology is not only applicable to SocialFi, but also supports multiple high-frequency use cases such as payments, NFT transactions, DeFi, etc. At the same time, our One Gas payment function and One Account system also provide greater convenience for users and developers.

It can be said that UXLINK One is not only a consumer-friendly chain, but also a developer-friendly chain. With our toolchain, developers can quickly build applications instead of reinventing the wheel.

Q 7: In the blockchain field, how does UXLINK One achieve a balance between ensuring chain performance and security while providing a user-friendly interactive experience?

A: Balancing consumer experience, chain performance, and security is one of our core goals in designing UXLINK One. We focus on the following aspects:

First is high-performance architecture.

First is the high-performance architecture. UXLINK One is based on Optimism Stake, which not only gives us high throughput and low latency transaction capabilities, but also ensures the scalability of the chain. This architecture enables us to provide a smooth user experience for high-frequency interactive scenarios, while significantly reducing Gas costs.

Next is a multi-level scalability design. We adopt strict verification mechanisms for cross-chain communication and reduce potential security risks through multi-layer protection strategies in smart contracts. In addition, we have also introduced an on-chain real-time monitoring and dynamic risk control system, which can quickly identify and respond to abnormal behaviors, ensuring the security of the entire ecosystem.

Finally, there is the optimization of user experience. Through chain abstraction and account abstraction, we hide the complex blockchain operations at the underlying level, allowing users to switch networks or manage Gas tokens on different chains. Even the fact that users have a wallet address is unnecessary. What users see is only the intuitive "one-click operation", while the complex processes such as cross-chain payments and data transmission are automatically handled by the system. On the premise of ensuring the stability of the underlying technology, this seamless interaction provides users with a smooth experience comparable to Web2.

We believe that through the collaborative design of architectural performance, security mechanisms, and user experience, UXLINK One can bring users and developers more comprehensive and high-quality blockchain services.
