About this Gig
Is your Web3 dApp broken, wallet connection failing, or smart contract interaction not working as expected?
I will troubleshoot and fix Web3 dApp issues involving MetaMask, WalletConnect, smart contracts, blockchain APIs, transaction flows, and frontend integrations.
I can help with:
- MetaMask and WalletConnect errors
- Smart contract integration issues
- Failed or stuck transactions
- Wrong network and chain switching problems
- React / Next.js Web3 bugs
- Wallet balance and account display issues
- Contract read and write failures
- RPC and blockchain API errors
- dApp frontend integration problems
- DeFi, NFT, DAO, and token dApp fixes
- Existing Web3 code troubleshooting
- Transaction status and confirmation issues
I work with EVM-compatible networks including Ethereum, Base, Polygon, BNB Chain, Arbitrum, and others.
Already have an existing dApp that is not working correctly? Send the error, project details, contract address, ABI, and network information.

FAQ
Can you fix MetaMask or WalletConnect connection errors?
Yes. I can fix MetaMask and WalletConnect connection errors, failed wallet prompts, wrong network issues, account detection problems, and broken Web3 login flows. I can troubleshoot React or Next.js dApps and repair wallet integration so users can connect, switch networks, and interact smoothly now.
Can you fix smart contract frontend integration issues?
Yes. I can troubleshoot smart contract frontend issues including failed read/write calls, incorrect ABI usage, wrong contract addresses, transaction reverts, approval problems, and broken functions. I can repair existing Web3 interfaces using your deployed contract, ABIs, network, and frontend code.
Can you fix failed or stuck Web3 transactions?
Yes. I can fix failed, stuck, or rejected Web3 transactions caused by network mismatch, gas settings, contract calls, wallet prompts, RPC issues, or frontend logic. I can review the transaction flow, identify the source of the error, and repair the dApp behavior in React or Next.js applications now.
Can you troubleshoot React or Next.js Web3 bugs?
Yes. I can troubleshoot React and Next.js Web3 bugs involving wallet state, contract calls, transaction handling, API requests, network switching, and blockchain data. I can review existing code, identify broken logic, and fix frontend integration issues without rebuilding your entire dApp securely.
Which blockchain networks can you troubleshoot?
Yes. I can work with Ethereum and major EVM-compatible networks including Base, BNB Chain, Polygon, Arbitrum, Optimism, Avalanche, and similar chains. I can fix wallet integration, RPC issues, contract connectivity, network switching, transaction states, and blockchain data problems for dApps today.
Can you fix DeFi, NFT, DAO, or token dApps?
Yes. I can fix Web3 dApps for DeFi, NFT, DAO, token, staking, minting, and other blockchain applications. I can troubleshoot wallet connections, contract interaction, transaction flows, blockchain APIs, network issues, and frontend bugs while working with your existing codebase and contracts safely.
Can you fix RPC or blockchain API errors?
Yes. I can troubleshoot RPC and blockchain API issues such as failed requests, rate limits, incorrect endpoints, missing data, slow responses, and network errors. I can review your provider setup, API calls, and frontend logic to restore reliable blockchain data inside your Web3 dApps or dashboards.
Do you need my private key or seed phrase?
No. Never send your private key, seed phrase, recovery phrase, or wallet password. I only need safe project details such as your dApp files or repository access, network information, contract address, ABI, error messages, and test wallet details when required to reproduce and fix the Web3 issue now.
What should I send before you start debugging my dApp?
Please send your dApp URLs or project files, framework, blockchain network, wallet being used, smart contract address and ABI if applicable, plus the exact error or feature that is not working. Screenshots, console errors, failed transaction hashes, and steps to reproduce the issue are very helpful!
Can you review my existing dApp and find the problem?
Yes. I can review an existing Web3 dApp and identify why wallet connections, smart contract calls, transactions, RPC requests, or frontend logic are failing. I can then fix the specific integration problems and test the corrected flows so your clients can interact with the application more reliably.
