MarbleCoin is an ERC-20-based cryptocurrency of the Marble Cards platform. This platform aims to enable people to convert any web page into a digital card. These digital cards are represented by non-fungible tokens (NFTs) and are based on the ERC721 standard. ERC721 refers to the token standard that dictates the creation of NFTs on the Ethereum network. Due to ERC 721 standard, users can create only one digital card for one web page.

MarbleCards generate each Marble card with its algorithm and give them a unique identity through patterns. These pattern designs are based on the content of the submitted web page. MarbleCards take this approach to generate Marble to reduce the chances of duplication.

The platform makes it possible for everyone to create a unique Marble card and put it into an auction. MarbelCards charges fees against every card creation. Once put in the auction, everyone gets a fair chance to bid on the created Marble card within a predetermined time. The creator of the card gets a commission if the card is sold. If nobody purchases in the auction, the card creator gets the ownership of the card. Moreover, when someone purchases these digital cards, they get the full authority to save, share, or trade. Marble card collectors can battle in the MarbleCards Arena to win rewards in cryptocurrency. Players can play as a voter and a battler on the MarbleCards Arena.

MarbleCoin is the native token of the platform. The ticker of the token is MBC. Users can get 30% discounts on Marble card creation when paying the creation fees. This currency uses Marblecoins to pay their employees' salaries, run the operation efficiently, and reward ecosystem participants. MarbleCards' core team has allocated 50% of the total token’s supply to themselves.

Johan Unger is the cofounder of MarbleCards. The maximum total supply of MarbleCoin tokens is 100,000,000 MBC coins.
