ShardVault Case Study: NFT Wallet for Luxury Asset Tokenization

ShardVault: Digitizing Luxury Ownership by Making Collectibles Investable with an NFT Wallet

Tanθ Software Studio partnered with ShardVault to develop a secure NFT wallet for investing in tokenized luxury goods and rare physical collectibles.

About ShardVault

ShardVault is a digital investment startup that enables users to buy, trade, and manage fractional NFTs tied to real-world luxury assets. From rare watches to fine art and classic cars, their platform unlocks access to high-value collectibles through tokenization. Their core need: a secure, intuitive wallet that could manage ownership, transfers, and secondary market trades—while remaining fully compliant and user-friendly.

The Challenge: What Was Holding Them Back?

Complexity of Real-World Asset Integration

Connecting blockchain-based NFTs to physical luxury items raised challenges around proof of ownership, custody, and transparency.

No NFT Wallets for Investment Use Case

Existing wallets focused on art or collectibles, not serious investors needing real-time value tracking, transfer locks, or trade windows.

Security Concerns Around High-Value NFTs

Users needed hardware-grade wallet security to protect digital shares of physical goods worth thousands to millions of dollars.

Poor UX for Fractional Ownership

Most wallets didn’t display or explain how NFT fractions worked, leaving investors confused about share value or exit options.

The Breakthrough: How Our NFT Wallet Changed the Game

Luxury Asset-Ready NFT Architecture

We developed smart contracts that linked each NFT to its physical item with metadata, legal docs, and third-party custody verification.

Fractional NFT Dashboard with Live Valuation

Wallet displayed ownership percentage, real-time asset value, dividend history, and tradability based on contract-defined holding periods.

Transfer Locks & Compliance Guardrails

Built-in restrictions allowed ShardVault to pause transfers, control asset windows, or flag trades under compliance review or legal hold.

Investor-Friendly UX and Financial Insights

Users received a dashboard similar to trading apps, showing returns, fractional liquidity, asset appreciation, and alerts for secondary sale periods.

Smart Features That Made a Difference

Fractional Ownership Overview

Users could view their exact NFT share in any asset, along with value growth, holding duration, and liquidity status in real time.

NFT-Backed Document Vault

Included embedded access to legal contracts, appraisal certificates, and custody documents directly tied to each NFT.

Role-Based Access for Portfolio Managers

Allowed multi-user access where family offices or investment managers could oversee or co-manage NFT portfolios with assigned permissions.

Time-Locked NFTs for Regulated Trades

Certain assets had smart contract-enforced holding periods or blackout windows to comply with legal or fractional ownership terms.

Built-in Exit & Trade Scheduling

Let users schedule sales or register for auction events when an asset opens up for redistribution or resale.

Insurance & Escrow Status Tracking

Wallet displayed insurance status, renewal dates, and escrow details so investors could confirm asset security at all times.

NFT-Linked QR Proof for Physical Redemption

For full shareowners, QR-based redemption flow allowed claiming physical assets securely with in-person authentication.

Multi-Chain Interoperability

Assets launched on Ethereum, Polygon, and upcoming RWA-focused chains were supported with dynamic sync and bridge-ready architecture.

How We Built It

Defined Custom Smart Contracts for Asset Classes

Each asset type—watches, art, cars—had tailored contract logic for ownership, compliance, dividends, and valuation updates.

Integrated RWA Custody APIs

Collaborated with third-party custodians to verify storage, condition, and chain-linked asset tagging for token integrity.

Built a Modular Portfolio Dashboard

Created a portfolio view similar to investment apps, designed to appeal to serious investors, not just crypto collectors.

Integrated Real-Time Valuation Feeds

Added APIs that pulled market prices, appraisals, or auction data to update wallet asset values dynamically.

Added Legal Doc Management Layer

Developed a secure interface for uploading, storing, and referencing legally binding contracts and ownership docs tied to NFTs.

Conducted Investor-Focused Usability Testing

Worked with early-access users, including asset managers, to streamline UI/UX for clarity, confidence, and investor-grade workflows.
