EterArt is the place where you can Buy, Collect and Sell digital version of arts based on ERC-721 compatible non-fungible or unique tokens on the Ethereum blockchain. While most tokens are fungible (every token is the same as every other token), ERC-721 tokens are all unique. Think of them like rare, one-of-a-kind collectibles. After you buy unique arts, you can just own it or sell it for any price you want.
