Project details

You will receive a clear, reproducible report for one defined EVM wallet or JSON-RPC integration issue. I will test the flow in a safe environment and document exact reproduction steps, expected versus actual behavior, annotated screenshots, relevant browser or RPC evidence, likely cause notes, and five focused regression test cases. When useful, I will also include a short screen recording of up to five minutes.

This service fits wallet connection, chain or network switching, public RPC calls, address validation, balance reads, ABI interaction errors, and sanitized error handling. I work with TypeScript, viem, Vitest, public RPC endpoints, and browser developer tools.

The scope is one defined issue. It does not include implementing a code fix, a full smart-contract audit, production fund handling, or signing unknown wallet messages. I will never request seed phrases, private keys, API secrets, verification codes, or production funds. One revision is included to correct or clarify the delivered report.

About Yang

Yang Y.Status: Offline
Web3 QA & Integration Developer | TypeScript, Ethereum
Shanghai, China - 4:30 pm local time
I help Web3 teams test wallet and RPC integrations, reproduce bugs, and deliver clear technical reports.

I can:
• Execute UAT scripts and record pass, fail, or blocked results with evidence
• Reproduce wallet, network, RPC, address, and token-balance issues
• Add focused regression tests with TypeScript and Vitest
• Work with Ethereum and EVM testnets using viem, React, and Node.js
• Provide concise developer handoff notes in English or Chinese

I built and deployed a read-only EVM Wallet Security Dashboard that validates addresses, switches between Ethereum Sepolia and Base Sepolia, reads native and configured ERC-20 balances, and sanitizes RPC errors. It is verified with automated tests and a production build.

I use public testnets and disposable test data. I do not need seed phrases, private keys, signatures, or production funds.

Steps for completing your project

After purchasing the project, send requirements so Yang can start the project.

Delivery time starts when Yang receives requirements from you.

Yang works on your project following the steps below.

Revisions may occur after the delivery date.

Confirm scope and reproduce the issue

I review the supplied requirements, confirm the safe test environment and acceptance criteria, then reproduce the defined wallet or RPC issue.

Collect evidence and analyze the likely cause

I capture reproducible evidence, compare expected and actual behavior, review relevant logs or RPC responses, and document scoped likely-cause notes.

Review the work, release payment, and leave feedback to Yang.
