WonderChain integrates practical blockchain technologies to enhance user convenience and participation accessibility. Core elements such as Account Abstraction, gas fee selection functionality, and a smart contract-based reward system are all focused on creating a user-centric structure that allows users to experience the Web3 environment in a seamless and intuitive way.

### 1) Application of Account Abstraction

To lower the entry barrier to Web3, WonderChain adopts Account Abstraction technology. This enables users to create a Web3 wallet through a simple social login—using platforms like Google, Apple, or SNS—rather than going through the traditional wallet creation process.\
It provides a user-friendly environment designed to support all types of users, from beginners unfamiliar with Web3 to advanced users, enabling smooth participation in the ecosystem.

### 2) Gas Fee Selection and Efficient Transaction System

In traditional blockchain systems, gas fees are one of the biggest obstacles to user experience. WonderChain introduces a gas fee selection feature using utility tokens, allowing users to interact with the ecosystem without needing a separate native token.

For example, users can pay gas fees with utility tokens earned through rewards. These tokens are automatically burned in the process, supporting the deflationary token model.\
This structure enables users to participate in the ecosystem without being burdened by gas fees, making the Web3 experience significantly more intuitive and user-friendly.

### 3) Smart Contract-Based Reward System

All user activity within the WonderChain ecosystem is managed through smart contracts. Rewards are automatically distributed based on predefined conditions related to the user’s actions in the ecosystem.\
This ensures transparency, trust, and automated fairness in operations, fundamentally preventing issues such as missed rewards or unfair distributions.\
In addition to reward distribution, smart contracts are also used across various functions including commerce transactions, DAO voting, and membership management—maximizing operational efficiency and security.

By integrating these core technologies around the user experience, WonderChain enables even users accustomed to Web2 environments to easily access a Web3 network—while realizing automated transparency and a sustainable deflationary economic model.
