FAQ
What do I need to get started?
Please share a brief about your project idea or whitepaper (if available). I’ll also need your preferred blockchain (e.g., Ethereum, BSC, Polygon) and any token details if you already have one.
Can you help me create a token for the DeFi dApp?
Yes! I can develop and deploy your custom ERC-20/BEP-20 token as part of the project, including features like burn, mint, pause, fees, etc.
Will the smart contract be secure?
Absolutely. I follow best security practices like input validation, reentrancy protection, and gas optimization. For advanced projects, I also offer a basic audit report.
Will you deploy the dApp on the blockchain?
Yes. I can deploy the smart contracts to the testnet (free) or mainnet (with your wallet and gas fee). I also assist with frontend deployment on platforms like Vercel, Netlify, or your own server.
Can you integrate wallet login like MetaMask or TrustWallet?
Yes, I can integrate wallet connect features (MetaMask, TrustWallet, WalletConnect) and even Sign-In with Ethereum (SIWE) for secure login.
Will you provide documentation or support after delivery?
Yes, I’ll deliver basic usage documentation and offer free support for 7 days after delivery. Extended support or feature upgrades can be provided at an extra cost.
Can I resell or rebrand the delivered project?
Yes. Once the project is delivered and fully paid, you have full rights to use, resell, or rebrand it.
