FAQ
1. Q: What types of Ethereum smart contracts can you create?
I specialize in any type of custom Solidity smart contract—such as tokens (ERC-20), NFTs (ERC-721), DeFi logic, utility contracts, and DApp contracts—delivered on Ethereum testnets (Sepolia).
2. Q: Do you also build the frontend?
A: Yes! In the Standard and Premium packages, I provide a React Web3 frontend with MetaMask integration, allowing users to interact with your contract in real-time.
3. Q: Will I own the code?
A: Absolutely—you’ll receive full ownership of the source code, including all smart contract files, frontend React code, and clear documentation.
4. Q: What do you need from me to get started?
A: Please send your project specs upfront: the contract’s intended function, if you take the standard or premium packages,the desired frontend actions, feature preferences (like minting rules or access control), and any UI mockups or detailed design ideas you have.
5.Q: Do you support mainnet deployment or other wallets?
A: Not yet—I currently support only MetaMask and focus on testnet deployment. Mainnet and other wallet integrations can be discussed as custom options in the future.
6. Q: Can I get help or fixes after delivery?
A: Yes—every Premium package includes 7 days of free post-delivery bug fixes and support to ensure everything works smoothly.
7. Q: Can you add extra features like royalties or access control?
A: Certainly! Premium packages already include options such as royalty systems, access control, reveal mechanisms, or pause/resume functions. Additional custom functionality can also be added as gig extras.
