FAQ
1. What tools or technologies do you use for blockchain and NFT game development?
I use Unity, Web3.js, Solidity, Vault SDK, and reliable NFT APIs to build Web3 games. I usually work with blockchains like Ethereum, Polygon, and BNB Chain, but I can adapt to your preferred network too.
2. Can you connect my existing NFTs or crypto tokens to the game?
Yes, absolutely! If you already have NFTs or tokens, I can safely integrate them into your game so players can use or earn them directly through gameplay.
3. Do I need to have my own smart contract first?
Not necessarily. If you have one, I’ll connect it. If not, I can create and deploy a custom smart contract for your game — whether it’s for minting NFTs, rewards, or marketplace trading.
4. Will my game include a play-to-earn (P2E) system?
Yes, if you want it to. I can design P2E mechanics that reward players with NFTs or tokens for completing levels, missions, or challenges.
5. What kind of wallets will players be able to use?
Your players will be able to log in and make transactions using MetaMask, Trust Wallet, Coinbase Wallet, and other Web3 compatible wallets.
6. Can you make the game run on web, PC, or mobile?
Yes! I build cross platform games that work smoothly on web browsers, desktop, and mobile devices so your players can access it anywhere.
7. Is it safe to connect wallets and NFTs in the game?
Definitely. I use secure API handling, Vault SDK, and best blockchain security practices to make sure every transaction and wallet connection is fully protected.
8. Can you build a marketplace inside the game?
Yes, I can. I can set up an NFT marketplace where players can buy, sell, or trade items safely using smart contracts and crypto payments.
9. Do you offer updates or support after delivery?
Of course! I provide post launch support and can help with game updates, new features, or bug fixes whenever you need them.
10. How long will it take to complete my blockchain game?
It depends on what you need a small NFT integration usually takes about a week, while a full play-to-earn Web3 game can take 3–6 weeks. Once you share your idea, I’ll give you a clear timeline.
