This project is a blockchain-based platform that allows anyone to invest in high-value art by purchasing fractional shares of real-world artworks. Built on the Flow blockchain, it leverages account abstraction (via Privy) to make the experience seamless—even for users with no prior crypto experience.

Users simply create an account using their email or social login, fund their wallet with fiat or crypto, and can then browse, purchase, and manage fractions of tokenized artworks. All ownership records are stored transparently and immutably onchain. The platform also provides a marketplace where users can resell their shares at any time, unlocking liquidity in an otherwise illiquid asset class.

By removing barriers to entry, minimizing fees, and offering a smooth, user-friendly experience, the project democratizes access to the art investment market. It empowers a new generation of collectors and investors to participate in the growth of the art world—without needing to be experts or have significant capital.

This project is built as a full-stack application leveraging modern web and blockchain technologies to make art investment accessible and seamless.

Frontend:

We use Next.js and React to create a fast, responsive user interface. This allows users to sign up, browse artworks, fund their account, and manage their art shares with a smooth user experience.

Authentication & Account Abstraction:

We integrated Privy for account abstraction, which means users can sign up and log in using email or social accounts without needing to manage a crypto wallet or seed phrase. Privy handles wallet management in the background, greatly lowering onboarding friction and making the experience feel like a regular web app.

Blockchain & Smart Contracts:

The backend operates on the Flow EVM.

• We developed custom smart contracts in Solidity that manage both the fractional ownership and trading of art pieces;
• Each artwork is tokenized as an ERC-721 NFT, representing the unique, real-world asset;
• Fractional ownership is implemented via ERC-20 tokens linked to each ERC-721 NFT, allowing users to buy, hold, and trade fractions of each artwork.

Notable Integrations & Hacks:

• Using Privy with Flow EVM and Solidity contracts required some custom bridging logic to sync user identity and wallet state across the dApp and blockchain, ensuring non-technical users never have to see a private key or manage a wallet.

Why these technologies?

• Flow EVM: Chosen for its scalability and user-friendly infrastructure, making onboarding and transactions faster and cheaper than legacy chains;
• Privy: Drastically improves onboarding and helps bring non-crypto users to the platform;
• Next.js/React: For building a web experience that feels as simple and modern as any non-blockchain app.

This stack allowed us to create a platform that feels frictionless for users, while still being fully non-custodial and decentralized.
