1. Responsible for writing, reviewing, and executing iterative functional test cases for the backend systems, official website, DApp, and mobile APP within Web3 projects, ensuring stable front-end and back-end integration across all platforms;

2. Independently complete interface testing for on-chain and off-chain systems, including test case design, execution, and issue regression for scenarios such as on-chain transaction calls, wallet authorizations, token transfers, and contract calls;

3. Write and maintain automated testing scripts applicable to Web and App, covering UI automation (Selenium/Appium) and API automation (Python + Requests), and adapt to multi-chain wallet connections (e.g., MetaMask, Phantom, OKX Wallet) for testing;

4. Assist daily in troubleshooting online issues within Web3 projects alongside the development and product teams, including typical problems such as wallet connection failures, abnormal on-chain transactions, gas calculation errors, and token not arriving;

5. Participate in issue tracking and continuous improvement following product launch, collecting on-chain/off-chain anomaly logs and user feedback to drive optimization and fixes of the DApp or backend services;

6. Regularly execute centralized regression testing tasks, covering backend, frontend, DApp, wallet authorization, and other modules, with a focus on the impact of new features on on-chain interactions and the accuracy of data synchronization.

1. Familiar with the basic architecture of Web3/DApp products and blockchain interaction logic, possessing complete experience in software testing processes, and able to independently write test plans, test cases, test reports, and other testing documentation;

2. Proficient in using tools such as Chrome F12, Fiddler, and Postman for packet capturing and identifying issues in on-chain and off-chain interfaces;

3. Familiar with defect management processes and skilled in using tools like JIRA for defect submission, tracking, and management;

4. Proficient in MySQL and common Linux commands, capable of assisting in verifying the consistency of off-chain database data with on-chain data;

5. Familiar with performance testing processes, understanding on-chain transaction performance metrics (such as transaction confirmation delay, throughput, transaction failure rate, etc.) and able to design and execute performance scripts;

6. Able to write UI automation scripts for web applications, accommodating complex interactions in DApps such as wallet authorization pop-ups and multi-wallet switching;

7. Capable of conducting UI automation testing for mobile Web3 applications, including processes like multi-chain wallet interactions, transfer authorizations, and on-chain asset displays;

8. Preferred qualifications: Understanding of EVM contract calls, familiarity with multi-chain interaction logic of Solana/TON/BSC, and experience in contract testing or security testing is an advantage.
