MADNFTs
Multi-chain NFT minting platform and marketplace. React frontend with wallet integration, GraphQL data indexing, and multi-language support across EVM and Cardano networks.
The Challenge
MADNFTs — a team of artists building creator-first NFT tools — needed a full-stack platform spanning multiple blockchains. The vision was ambitious: a single minting and marketplace experience that worked across both EVM chains and Cardano, with wallet connectivity, multi-language support, and the backend infrastructure to index on-chain data in real time. They needed a partner who could deliver both the user-facing React application and the blockchain data layer underneath it.
Our Approach
- Built the React frontend for their NFT minting platform — wallet connection flows, creator profiles, collection browsing, and the minting experience itself. Integrated MetaMask and Cardano wallet providers for seamless multi-chain access.
- Implemented full multi-language support across the platform, ensuring the interface was accessible to their growing international creator community.
- Deployed and operated self-hosted Graph Nodes to index multiple blockchains simultaneously. Designed GraphQL schemas and APIs to serve NFT metadata, marketplace transactions, and on-chain activity to the frontend in real time.
- Built the queryable data infrastructure that powers search, trending collections, creator rankings, and transaction history across chains.
The Outcome
MADNFTs launched a fully operational multi-chain NFT platform where creators can mint, list, and sell across EVM and Cardano networks from a single interface. The combination of a polished React frontend with robust blockchain data infrastructure gave them a differentiated product in a crowded space — built for creators, not speculators.
Key Takeaways
- Multi-chain platforms need careful abstraction — the user should never have to think about which chain they are on.
- Blockchain data indexing requires schema design driven by query patterns, not chain structure.
- Self-hosted Graph Nodes give control and reliability that third-party hosted alternatives cannot match.
- Internationalisation from day one is far cheaper than retrofitting it later.
