We build custom NFT marketplaces with sophisticated auction mechanics, creator royalty enforcement, and seamless multi-chain trading experiences.
The NFT marketplace landscape has matured beyond simple listing-and-buying platforms. Today's successful marketplaces require sophisticated order book systems, auction mechanics, royalty enforcement, collection aggregation, and seamless user experiences that abstract away blockchain complexity. Arthiq builds NFT marketplaces that meet these standards and compete with established platforms.
Whether you are building a general-purpose marketplace, a curated art platform, a music NFT exchange, a gaming asset marketplace, or an enterprise NFT solution, our team delivers the full technical stack. From smart contract order matching to frontend wallet integration, we own every layer of the application.
Our marketplace contracts support ERC-721, ERC-1155, and custom token standards. We implement both on-chain and off-chain order systems depending on your gas efficiency and decentralization requirements. The result is a platform that provides a smooth trading experience while maintaining the trustless guarantees that make NFTs valuable in the first place.
At the core of every NFT marketplace are the listing, bidding, and settlement contracts. We design these with careful attention to gas costs, MEV resistance, and upgrade flexibility. Our marketplace contracts handle fixed-price listings, English auctions, Dutch auctions, and offer-based trading — all with configurable fee structures and royalty distribution.
Royalty enforcement is a critical and evolving challenge. We implement on-chain royalty systems that work with the ERC-2981 standard and can integrate with operator filter registries to enforce creator royalties even on secondary sales. For platforms that need stronger enforcement, we build custom transfer restriction mechanisms.
Our contracts also include collection management features — lazy minting for creators who want to defer gas costs, collection whitelisting for curated platforms, and batch operations for users who want to manage multiple NFTs in a single transaction. Every feature is built with upgradeability in mind, so the marketplace can evolve without disrupting existing listings.
A marketplace is only as good as its user experience. We build responsive, performant frontends using Next.js and React with wagmi and viem for wallet connectivity. Users can connect with MetaMask, WalletConnect, Coinbase Wallet, and other popular providers through a unified interface.
The frontend handles real-time price updates, collection browsing with filtering and sorting, activity feeds, user profiles with transaction history, and the complete buy-sell-bid flow. We implement image and metadata caching to ensure fast load times, and we build collection page experiences that showcase NFT attributes and rarity information.
For mobile experiences, we optimize the wallet connection flow and transaction signing process to work smoothly on mobile browsers and in-app browsers within wallet applications. The result is a marketplace that captures trading activity from every device and platform your users prefer.
NFT marketplace data — listings, sales, bids, transfers — lives on-chain and needs to be indexed for fast querying. We build custom subgraphs using The Graph protocol that index every marketplace event and make it available through a GraphQL API. This powers search, activity feeds, collection statistics, and user dashboards.
We also implement full-text search across collection names, NFT metadata, and creator profiles. For large marketplaces, this involves building dedicated search infrastructure that stays synchronized with on-chain state. Analytics dashboards provide marketplace operators with trading volume, user metrics, fee revenue, and collection performance data.
For multi-chain marketplaces, our indexing layer aggregates data from multiple networks into a unified view. Users can browse and trade NFTs across Ethereum, Polygon, Arbitrum, and Base without switching between separate interfaces or understanding which chain their assets live on.
Launching an NFT marketplace requires more than code deployment. We help with initial collection onboarding, creator outreach tooling, liquidity bootstrapping through featured collections, and integration with existing NFT aggregators to drive discovery. Our team handles the technical deployment across testnets and mainnet, including contract verification and parameter configuration.
Post-launch, we provide ongoing development and operational support. This includes new feature development, smart contract upgrades for the marketplace protocol, monitoring for unusual trading patterns, and scaling the indexing infrastructure as trading volume grows. We also build admin tools for marketplace operators to manage collections, enforce policies, and configure fees.
Arthiq has built marketplace infrastructure that processes real trading volume. We understand the practical challenges of running a live NFT platform — from handling gas spikes during popular mints to managing metadata for collections with tens of thousands of items.
