SOLID STATE

is a decentralised market for trading shares in Artworks. The owner of a collection artwork/s maintains storage and security of the artwork, while allowing for the artwork to realise its investment value by allowing others to invest in it as parts/shares. These parts/shares are ec20 tokens. Test Server

The platform is broken into 2 contracts. The Artwork contract and The Gallery contract.

Each Artwork Contract manages its own buy and sell orders / trades. The price of the Artwork's shares adjusts the artworks price. Ultimately "the market" defines the price of the artwork.

The Gallery contract is a group of lists (collections) of Artworks with a visiblity switch.

The project directory structure:

• bots/ - Scripts for preparing trade data for tests etc
• contracts/ - Smart Contracts / Brownie
• front_end/solid_state/ - React Front End
• rest_api/ - Node Rest Api and App Server
• tools/ - Setup Tools
