A decentralized cryptocurrency exchange (DEX) cuts out the middleman by facilitating deals via and atomic swaps. The cryptocurrency is never in the possession of an escrow service. The platform merely connects the P2P participants.
No Central Authority
Because there is no central authority to hack or shut down, DEX development will likely be the focus as crypto has gained popularity. Recently, the Securities and Exchange Commission went after EtherDelta’s creator, Zachary Coburn. The SEC charged him with operating an “unregistered securities exchange” because the platform did not register as an exchange or file for an exemption after the 2017 DAO Report. Coburn has already settled the charges, though he did not admit to or deny the charges. He paid $300,000 in disgorgement, $13,000 in pre-judgement interest and a $75,000 penalty.
We will likely see more decentralized exchanges where the creator is unknown to avoid dealing with the SEC. was smart- don’t disclose your identity if you’re creating competition to the government. Platforms will also have to restructure to avoid having order books on a centralized server as EtherDelta did.
Anonymity, But More Difficult To Use
DEX platforms offer anonymity, but the trade-off is that the platforms are often harder to use. Fees are reduced because there is no central authority looking to take their cut. Since DEXs are not managed by a central party, users do not need to disclose personal information like their photo ID and address to trade.
Because Decentralized Exchanges are harder to use, they do not have the same liquidity that you find in centralized platforms. Additionally, if you lose your password, you can’t contact customer support. There is no third party to reverse any transactions.
These platforms also do not offer margin trading and stop losses like centralized platforms do. I don’t necessarily see that as a negative as that is one of the many factors that lead to the financial crisis of 2008 in the United States. Decentralized exchanges can also list an or token because they don’t have a central server to shut down. Because of KYC and AML regulations, legitimate Decentralized Exchanges do not support fiat conversions, as this would introduce a point of .
Another important thing to note is that the keys entered are not transmitted over the network, but stored in the browser cache. Make sure to protect yourself from phishing sites with extensions like , which will alert you if they feel you have gone to a potential phishing site.
There are two types of decentralized exchanges: currency-centric and currency-neutral.
Currency-centric exchanges are built on top of singular platforms like or .
Currency-neutral exchanges connect different native . No conversion coin is needed as trades are peer-to-peer.
