QA tester for a Web3 game (one-time testing)

Budget: 6000 UAH Deadline: 5 days

Good day! I have been doing QA for web applications for several years — and the task is specifically to break, not just "pass": I test logic, APIs through DevTools and Postman, and apply load with quick clicks. Notably, on one drop, I caught a double charge: I managed to send the transaction twice before the balance updated, a classic race condition in economics, exactly your abuse scenario. For Web3, I use MetaMask and Phantom, running on-chain transactions in the testnet and viewing everything through the explorer. I have also tested games. For such a one-time deep run (wallet, transactions, economy, load, PC + mobile), I ask for 6000 UAH, and I will provide a report with clear reproduction steps and screenshots. If you provide the build, I will start.

Budget: 27000 UAH Deadline: 5 days

We can take this as a technical QA audit of a Web3 game. The rate is 42,000 UAH for 4-5 working days if it is one testing cycle without a full retest after fixes. July 15 is suitable if the build, test wallets, and test balance are ready to start.

Experience in QA includes web applications, personal accounts, payments, complex business logic, roles, and transactional scenarios. An example of a critical bug is when a user's double action created two charges for one order because the payment state was not blocked between the click and the payment system's response. This is exactly the type of problem that can be costly in a game with an economy.

We work with Web3 as a technical risk, not just as a trendy term. We check the connection to MetaMask or Phantom, transaction signing, behavior on reject, pending, failed, resending, network change, balance shortage, and desynchronization between on-chain state and internal economy. We will also check abuse scenarios - rapid clicks, repeated requests, non-standard sequences of actions, DevTools, Postman, testnet explorer.

We conduct testing not as a way to complete the game, but as an attempt to break the logic =)

Good day!

I have about 10 years of experience in software testing (web, API, mobile). I have worked with functional, regression, UI, and API testing, as well as integration testing.

I have experience testing mobile applications (Android and iOS) and my own set of testing devices. I also have experience testing microservice architecture, integrations, and asynchronous systems (RabbitMQ). In my work, I use Postman, Fiddler, Docker, Git, SQL, as well as monitoring systems (Kibana, Grafana) and CI/CD (GitLab CI).

I also have about a year of experience in AI automation. Here are a few examples of workflows I recently created:
- Telegram news channel with AI message processing
- Chatbots for support
- Creating a knowledge base for the company
- Various automations specifically for QA (creating cases with subsequent analysis and documentation, automating work with databases, etc.)

Recently, I have worked on projects:

• https://sqlbackupandftp.com / https://sqlbak.com — database backup automation services.

• https://expofp.com — SaaS platform for event planning and management.

• https://lunu.io — blockchain project, cryptocurrency payment gateway, and Web3 payment ecosystem.

I would be happy to tell you more about my experience. Expand

Budget: 1000 UAH Deadline: 1 day

I have 3 years of experience in manual testing (Manual QA). I tested web and mobile applications, found bugs, and described them in bug reports. I created test cases and checklists, verified new functionality, and worked in a team with developers. Detail-oriented and responsible.

Budget: 4500 UAH Deadline: 5 days

Good day. I have experience in testing in Web3. Specifically, I have conducted transactions on the Sepolia test network (from sending to confirmation in the explorer. I also checked problematic cases - a stuck transaction due to low gas, a rejected signature.). I am also familiar with the specifics of Solana.

I can check the connection through the following wallets - MetaMask, Phantom, and Trust Wallet.
I test on real devices: Windows, iPhone, and Android.

The price for the project is 4500 UAH. As for the timeline - 5 days (but it depends on the volume of the game itself).

Budget: 5000 UAH Deadline: 7 days

Good day!

I have experience in manual testing of web applications, websites, and complex integrations, as well as a technical background in web development and cybersecurity, which allows me to identify not only functional bugs but also potential vulnerabilities and business logic abuse scenarios.

Among the interesting critical issues I found during testing were authorization errors and incorrect access rights checks that allowed access to other users' data by altering request parameters. I also worked on SSRF testing, API integrations, and business logic bypass scenarios.

I have practical experience working with Web3 as a user:

MetaMask;
Phantom;
WalletConnect;
testing interactions with dApps;
executing on-chain transactions;
working with test networks and blockchain explorers.

For testing, I use DevTools, Postman, network traffic analysis, API checks, and various load and user behavior scenarios.

I also have experience testing web games and game mechanics, including checking resource balance, economy, reward systems, abuse scenarios, and searching for opportunities to gain an unfair advantage.

I am ready to conduct comprehensive testing of:

authorization and wallet connections;
on-chain and in-game transactions;
game economy and mechanics;
load scenarios;
PC and mobile browsers;
UX and stability.

Based on the results, I will provide a structured bug report with reproduction steps, priorities, screenshots, and recommendations for fixes. Expand

Budget: 15000 UAH Deadline: 3 days

we have an almost ready approach for testing a web3 game - checklists can be quickly adapted to your build and critical scenarios can be executed on 15.07 =)

Evaluation - 15000 UAH for 3 days of work. The cost includes functional testing, wallet checks, transaction verification, game logic, economic abuses, mobile and desktop browsers, as well as a report with reproduction steps, screenshots, environment, and bug priorities.

We have experience in complex web systems, dashboards, financial logic, automation, and products with transactional scenarios. An example of a critical bug is double charging of the balance when quickly repeating a request and unstable interface state, where the user saw one amount while the backend processed another. Such issues are often not visible during regular testing; they need to be broken through parallel actions, devtools, APIs, and repeated scenarios.

In web3, we have worked with wallet connections, signature logic, transaction status checks, testnet environments, and explorers. For testing, we can go through MetaMask, Phantom, behavior when rejecting a signature, transaction hanging, network switching, repeated clicks, balance shortages, and desynchronization between on-chain state and internal economy.

Regarding the game part, I would look not only at the map, mining, and drops but also at abuses - rapid clicks, action repetitions, simultaneous tabs, network interruptions, mobile browsers, extreme balance values, and scenarios where UX pushes towards erroneous actions. Look, there’s a nuance... in web3 games, the most dangerous bugs often live not in the button but between the game state, transaction, and internal accounting.

> Question 1 - which network or test network is being used, and are there separate test tokens for payment verification?
> Question 2 - do you expect only a manual report, or also a short set of regression scenarios for future builds?

Similar logic cases from Ingello:

> https://business.ingello.com/vorfahr - product automation with business logic, integrations, and scenarios where process resilience is important
> https://systems-fl.ingello.com/ua - main page of Ingello Systems for the exchange

If the build is available on 15.07, I can be in touch within the exchange and start with a brief clarification of the environment, so we don’t have to play telepathy, because telepathy in QA, unfortunately, has poor test coverage )) Expand

Good day!

I am interested in your project.

I have experience in manual testing of web applications, and I pay close attention to bug finding and documentation. I also have practical experience using Web3 wallets and interacting with dApps and on-chain transactions as a user.

During testing, I pay special attention to edge cases, incorrect user actions, logic verification, UX, authorization, transactions, and possible ways to abuse mechanics. I document bugs with clear reproduction steps, expected and actual results, as well as necessary screenshots.

I would appreciate it if you could send more information about the build and the expected scope of testing. After reviewing, I will be able to provide an exact rate and timeline for completion.

I look forward to collaborating! Expand
