DDEX is a user-friendly decentralized exchange for Ethereum-based tokens. Building on top of Ethereum smart contracts and the 0x protocol, DDEX allows users to trade ERC-20 tokens from wallet to wallet. As a decentralized exchange, DDEX does not rely on third parties to hold users’ assets comparing to large, centralized exchanges. The trading on DDEX occurs directly between buyers and sellers in a peer-to-peer (P2P) network via an automated process.
