Forever Library
The Challenge
Forever Library needed a fully custom NFT marketplace — not an OpenSea clone. Their platform lets users permanently preserve digital content on-chain as NFTs, with UX tailored to their community. The founder had the vision but no technical team to execute it. They needed engineers who could own the entire build — smart contracts, wallet integration, marketplace logic, and frontend — end to end.
What We Built
- Custom EVM-compatible smart contracts for NFT minting and marketplace transactions
- Wallet integration supporting MetaMask and compatible Web3 wallets
- Full marketplace UI: browse, mint, list, and buy NFTs
- Custom minting flow tailored to Forever Library's digital preservation use case
- Deployed to production on Vercel
The Result
- Fully functional NFT marketplace, live at foreverlibrary.xyz
- Delivered end-to-end: smart contracts through to production deployment
- Client had full understanding of the system at handoff
“Tensai unlocked a whole new world of possibilities for me. I could not have gotten Forever Library off the ground without their guidance and expertise. Throughout our time working together, they have always taken the time to make sure our understanding is aligned and that we are working toward the larger vision I'm trying to bring to life. Whether we are building self-serve NFT storage solutions, implementing new and improved minting contracts, or developing user-friendly frontend interfaces, their ability to help bridge the gap between my goals and my level of technical knowledge has been invaluable. I tend to send a lot of detailed notes and feedback, and Tensai always takes those to heart and implements them faithfully, or gives me thoughtful feedback when a different approach would work better. It has felt like a genuinely collaborative partnership throughout. Given all of this, as well as their professionalism and courteous communication, I cannot recommend Tensai more highly.”
