Service details

Looking to launch an NFT project that actually works smoothly for users, not just a flashy demo that breaks at mint time? I’m an NFT Developer and I build decentralized applications (dApps), NFT marketplaces, and crypto wallet integrations with clean UX and reliable smart contract logic.


Whether you need a simple minting website, a full marketplace, or wallet connect added to your existing platform, I can turn your requirements into a functional Web3 product with clear milestones and clean delivery. I focus on building features that users can understand easily, while keeping the smart contract side structured and scalable.


What I can build for you includes NFT minting dApps using ERC-721 or ERC-1155, marketplace features such as listing, buying, selling, offers or bids, and royalty support, and smooth wallet integrations like MetaMask, WalletConnect, and Coinbase Wallet. I can develop smart contracts using best-practice patterns commonly based on OpenZeppelin, and set up admin-ready configurations for collection settings, mint pricing, supply limits, whitelist flow, and metadata handling.


You will receive clean code, organized project structure, and a working demo so you can review progress early instead of waiting until the end. I can also support deployment on testnet first for testing, and then assist with mainnet deployment based on your selected chain.


If you have any questions, inbox me and I will guide you.

FAQs
What do you need to start the project?

Share your idea, required features, preferred blockchain (Ethereum/Polygon/BSC etc.), number of collections, royalty settings, and any design reference (Figma/website examples). If you don’t have specs, I can help you define an MVP first.

Can you build both minting and a full NFT marketplace?

Yes. I can build a simple minting dApp, a marketplace MVP, or a complete marketplace with features like listings, purchases, bids/offers, royalties, and admin control depending on package and scope.

Which wallets can you integrate?

Common options include MetaMask, WalletConnect, and Coinbase Wallet. If you need a specific wallet or custom connection flow, tell me and I’ll implement it based on your target users.

Will you deploy the smart contracts and dApp?

I can deploy to testnet first for verification, then assist with mainnet deployment. You’ll need to provide the deployment wallet and gas fees. I’ll guide you through the safest process.

Do you provide security or audits?

I follow best-practice contract patterns and basic security checks, but a full third-party audit is recommended for high-value projects. If you want an audit-ready structure, I can help prepare the code and documentation.
