We future-proof your marketplace for high volume. We design platforms with multi-chain support (e.g., Ethereum, Solana, Polygon) and strategically integrate Layer-2 scaling solutions. This integration enables features like Lazy Minting (gas-free listing) and batch transactions, dramatically reducing user transaction costs and enhancing platform throughput.
We equip your marketplace with sophisticated financial engines. Our expertise includes developing fully on-chain logic for flexible monetization models, including timed, dynamic Auctions and Bidding systems, as well as integrating mechanisms for fractional NFT ownership.

We don’t just build apps we deliver industry-standard, certified solutions that are secure, scalable, and designed to help your business grow in today’s fast-paced digital world
We execute every project using an agile, security-centric roadmap, ensuring your custom marketplace is launched quickly, securely, and aligned perfectly with your niche and growth strategy.
The process begins with defining your unique niche (Art, Gaming, Real Estate, etc.) and competitive advantage. We select the optimal blockchain (Ethereum, Solana, Polygon, etc.), determine the fee structure, and design the core platform architecture to support maximum scalability and transaction speed.
Our design team drafts wireframes and interactive prototypes to visualize user flows, screen layouts, and app structure. You review and provide feedback ensuring the design aligns with your vision and brand identity.
This is the core on-chain logic. We write, review, and optimize smart contracts (ERC-721/ERC-1155) for minting, secure ownership transfer, and automated royalty distribution. Simultaneously, we set up IPFS (InterPlanetary File System) for decentralized, tamper-proof storage of the NFT metadata and media files.
We build the high-performance application layer, connecting the responsive frontend (React/Angular) with a scalable backend (Node.js/Python). Crucially, we integrate secure, seamless third-party services, including popular crypto wallets (MetaMask/WalletConnect) and any necessary fiat payment gateways for smooth user onboarding.
Before mainnet launch, the entire platform undergoes a security deep-dive. We run extensive functional, load, and unit testing. The smart contracts are subjected to internal and/or third-party audits to check for vulnerabilities like reentrancy and access control flaws, ensuring the code is tamper-proof and funds are secured.
We manage the full deployment to the chosen blockchain and web infrastructure (leveraging CI/CD pipelines for automation). Post-launch, Junkies Coder provides continuous monitoring, security patching, and iterative feature development to ensure the marketplace scales efficiently, adapts to market trends, and maintains peak performance.
we consistently stay ahead of the competition by using the latest tools and technologies in mobile app development. Our commitment to innovation ensures superior services that meet
Choosing to outsource your Custom NFT Marketplace development to Junkies Coder is a powerful strategic move. It is the most effective way to secure specialized, audited blockchain talent at a competitive cost, ensuring your platform is launched swiftly, securely, and with the necessary architecture to scale into a dominant player in the decentralized digital economy.

NFT Marketplace development is highly niche, requiring mastery in smart contract auditing, specific token standards (ERC-721/1155), and multi-chain architecture. Outsourcing allows you to bypass the long, costly process of recruiting and retaining these highly sought-after, expensive blockchain engineers. You instantly gain access to a pre-vetted, expert team ready to start.
Outsourcing to regions like India offers a drastic reduction in development costs. You leverage lower operating expenses and competitive hourly rates (often starting much lower than Western rates) while maintaining high quality. This strategic decision frees up capital to invest in marketing, community building, and obtaining exclusive NFT collections, which are critical for marketplace success.
A specialized outsourcing partner follows established, optimized processes for NFT development, from smart contract generation to front-end integration. They can launch a fully functional Minimum Viable Product (MVP) far quicker than a newly formed in-house team, ensuring you capitalize on market trends and gain first-mover advantages.
Blockchain code is immutable, making security auditing non-negotiable. Outsourced firms have a reputation to maintain and integrate rigorous smart contract auditing and security protocols as standard practice. This expertise minimizes the risk of vulnerabilities, exploits, and costly errors post-launch, protecting both your platform and your users’ assets.
The NFT landscape requires flexibility across networks (Ethereum, Solana, Polygon). Outsourcing ensures your marketplace is architected for immediate multi-chain support and integrates Layer-2 scaling solutions (like Lazy Minting) from day one, allowing your platform to handle massive user growth and high transaction volumes without compromising speed or incurring high gas fees.

The cost is highly dependent on complexity (e.g., single-chain vs. multi-chain, basic fixed-price sales vs. complex auction systems). A basic custom marketplace (MVP) typically starts around $16,000 to $30,000 and takes 3-5 months to develop. However, by partnering with Junkies Coder in India, you access specialized talent at a significantly lower hourly rate (often starting from $50/hr), ensuring you get a robust, feature-rich product at an optimized cost.
Security is our paramount concern because blockchain code is immutable. Our process includes rigorous internal auditing throughout development, focusing on common vulnerabilities like reentrancy, gas limit issues, and logic flaws. We strongly recommend, and can manage the process for, a final independent third-party security audit of the smart contracts (ERC-721/1155) before the mainnet launch to provide maximum assurance and trust.
Multi-Chain integration means your marketplace can list and trade NFTs from different blockchains like Ethereum, Solana, and Polygon, broadening your market reach and liquidity. Layer-2 integration is vital for scalability and cost: it enables features like Lazy Minting (gas-free listing) and faster transaction speeds, crucial for high-traffic platforms to avoid excessive gas fees for your users. We architect your platform for both from day one.
We integrate both! The core marketplace functionality relies on crypto wallet integration (like MetaMask and WalletConnect) for secure transaction signing. However, to attract mainstream users, we integrate fiat payment gateways (crypto on/off ramps), allowing users to buy crypto with a credit card or bank transfer directly within the platform. This maximizes accessibility and conversion rates for non-crypto-native buyers.
