The name DeX indicates that the exchange is a decentralized exchange, which implies that it has decentralized servers, making it difficult to hack. AfroDex is an African decentralized digital assets exchange based on the Ethereum blockchain, where users may trade solely Ethereum and Ethereum-based tokens. This exchange, which debuted in 2019, does not offer much information about itself or its trading activity. On CoinMarketCap, it is even labelled as an Untracked Listing. AfroX, the exchange's own token, was likewise developed on the Ethereum network.
I cannot guarantee that this exchange is still operational; users should conduct their own research.
