A decentralized exchange is an exchange market that does not rely on a third party service to hold the customer's funds. Instead, trades occur directly between users (peer to peer) through an automated process. This system can be achieved by creating proxy tokens (crypto assets that represent a certain fiat or crypto currency) or assets (that can represent shares in a company for example) or through a decentralized multi-signature escrow system, among other solutions that are currently being developed.
