FAQ
Q1: Which blockchains do you support?
Answer: EVM chains (Ethereum, BSC, Polygon, Arbitrum, Avalanche, Base) as well as Solana and TON. Message me first to confirm specific chain compatibility.
Q2: What's the difference between Basic and Standard packages?
Answer: Basic is smart contract development only. Standard is a complete dApp including the smart contract and a React/Next.js frontend with wallet integrations (MetaMask, WalletConnect).
Q3: Do you perform security audits on smart contracts?
Answer: Every contract I write undergoes a manual review for common vulnerabilities (reentrancy, access control). Premium package includes a formal audit report.
Q4: Who pays the gas fees for deployment?
Answer: Gas fees are paid by you (the owner) to the network. I will guide you through testnet deployment first so you know exactly what to expect on mainnet.
Q5: Can you customize or fork an existing protocol?
Answer: Yes, decentralized exchange (DEX) integrations and NFT marketplace clones are core to my services. Message me to discuss custom requirements and scope.
Q6: Will the smart contract be verified?
Answer: Yes, all deployed contracts are verified on Etherscan or the target block explorer for public inspection and credibility.
Q7: Do you provide source code and documentation?
Answer: Yes, you get full ownership of the source code, project files, deployment scripts, and a detailed README guide.
Q8: What do you need from me to start?
Answer: Share your project concept, target blockchain, required features, references (similar platforms), and timeline before ordering.
