JOYSO, the Ethereum based exchange, offers the speed of a centralised platform while providing the security and privacy of a decentralized exchange. This hybrid exchange (HEX), able to handle all ERC20-compatible tokens, eliminates the need to trust a central exchange with your private key or personal information, reducing to a historical minimum any opportunities for hacking. It takes order placement and order matching off-chain, substantially improving the user experience compared to decentralized exchanges.
