RWA Sports Cards

RWA Sports Card Trading Platform

This project was a Web3 platform designed for real-world asset (RWA) trading and fractional ownership of graded sports cards. The system was built using React, C#, Solidity, and Postgres, allowing for a clear separation between physical custody and on-chain settlement. The team progressed to an MVP-level backend and infrastructure buildout before the lead founder abruptly halted funding.

Overview

A tokenised asset platform enabling users to trade fractional ownership of real-world graded sports cards, while the physical assets remained securely stored by a licensed custodian. The goal was to combine traditional asset integrity with on-chain liquidity.

Features and Capabilities

Custody and trade were deliberately separated. While the cards were held in a secure vault by the platform operator, ownership changes took place through smart contracts. Each sports card was represented as an ERC-721 token, capturing its unique identity and provenance. These NFTs could then be fractionalised into ERC-20-like shares, allowing for partial ownership and seamless trading. Wallet-to-wallet transfers settled instantly on-chain, without affecting the underlying physical custody. The platform also supported white-label integrations, enabling business partners to deliver custom-branded user experiences with minimal engineering overhead.

Project Delivery

The system architecture was modular and scalable, with carefully mapped out. Solidity smart contracts were written to handle the card vaulting logic, track ownership, and manage settlement workflows. The backend was developed using C# and .NET Core, featuring a RESTful API and documented with Swagger. PostgreSQL powered the database, supporting asset registries, ownership ledgers, and custody logs.

On the frontend, a React-based web app was built with integrated wallet support and dynamic display of tokenised assets. Wireframes were created for both standard and white-labeled versions of the interface. CI/CD was managed via Jenkins and Helm, with a Kubernetes-based setup for service orchestration and full AWS environments for development and staging.

Status & Outcome

The project reached a solid MVP milestone with backend delivery, database structure, smart contract specifications, and an early-stage frontend. CI/CD pipelines and cloud deployment were also operational. Despite the lead founder pulling funding unexpectedly, the architecture remains highly reusable and well-suited for future tokenised RWA projects, including watches, art, or sneakers.
