Decentralized exchange

A decentralized exchange (DEX) is a cryptocurrency exchange which operates in a decentralized way, i.e., without a central authority. Decentralized exchanges allow peer-to-peer trading of cryptocurrencies.[1]

Because users do not need to transfer their assets to the exchange, decentralized exchanges reduce the risk of theft from hacking of exchanges.[2][3] Decentralized exchanges can also prevent price manipulation or faked trading volume through wash trading,[4] and are more anonymous than exchanges which implement know your customer requirements.[5]

There are some signs that decentralized exchanges have been suffering from low trading volumes and market liquidity.[1][5] The 0x project, a protocol for building decentralized exchanges with interchangeable liquidity attempts to solve this issue.[6]

List of Decentralized exchanges[edit]

Decentralized exchanges come in varying degrees of decentralization, where different exchanges decentralize different components. The cost of decentralization is usually paid for in user experience, such as Bisq's fiat pairing where users must put their Bitcoins in a 2/3 multisignature wallet until a fiat transfer is confirmed; where the buyer, seller and a community trusted dispute arbitrator each hold a key.[7]

Huobi runs a decentralized exchange called "HADAX" (Huobi Autonomous Digital Asset Exchange), with community voting for which coins to list.[20][21] Binance is developing a decentralized exchange.[4]


Due to a lack of KYC process, and no way to revert a transaction, users are at a loss if they are ever hacked for their passwords or private keys.[22]

Degrees of Decentralization[edit]

A decentralized exchange can still have centralized components, whereby some control of the exchange is still in the hands of a central authority. A notable example being IDEX blocking New York State users from placing orders on the platform.[15]
