Carboneum is a decentralized social trading platform built on the Ethereum blockchain, designed to allow novice cryptocurrency traders to follow and automatically replicate the trading strategies of more experienced investors. The project, which also issued its own utility token (C8), was developed by the team behind Four-Excellence Co., Ltd., the creators of the popular Thai stock market application StockRadars. The platform aimed to democratize trading by creating a transparent and accessible environment for copy trading, connecting users to multiple cryptocurrency exchanges. However, public activity and development appear to have ceased around 2019-2020.
