Owning Space, Virtually
How We Built a 3D NFT-Based Advertising Platform on the Ethereum Blockchain
Project Overview
This one-of-a-kind platform lets users purchase virtual plots of land in space—not just for fun, but as a bold, creative advertising opportunity. Each land parcel is minted as an NFT, and buyers can claim ownership and transfer it to their wallet.
SoftCode led the full development of this experience—from the to the , including backend systems for minting and transfer.

The Challenge
- A smooth, immersive 3D interface for land selection
- Secure NFT minting and transfer on the Ethereum blockchain
- Wallet connection, NFT claiming, and OpenSea visibility
- A reliable backend for handling purchases and blockchain communication
How We Solved It
We combined blockchain tech, immersive design, and a clean backend architecture to deliver a seamless NFT experience.
Immersive 3D Interface
Built a real-time 3D map of space using Three.js, allowing users to visually explore and select virtual land.
Blockchain & NFT Integration
Created scripts to mint NFTs and integrated wallet functionality for users to claim and transfer assets to their Ethereum address.
Backend + OpenSea Sync
Developed a Node.js backend to handle NFT creation, user transactions, and automatic syncing with OpenSea for visibility.
Our Implementation
The project involved deep coordination between frontend visuals and backend Web3 logic.
3D Frontend with Three.js
We created an interactive map of space where each clickable plot of land represented a unique NFT. Users could zoom, explore, and select tiles directly in the browser—making the buying process fun and visually driven.
Backend + Blockchain Integration
Our Node.js backend handled user purchases, NFT generation, and communication with the Ethereum network. We generated minting scripts that created NFTs with unique metadata for each plot, then made them transferable to the buyer’s wallet.
We also ensured each transaction was reflected in OpenSea, giving users access to their NFT in the broader Web3 ecosystem.
The Impact
Our team delivered significant improvements across all key metrics.
