Radar Relay

Radar Relay is an exchange that allows trading of Ethereum-based tokens using a MetaMask wallet or Ledger Nano S wallet. Other wallets you can integrate include Parity and Mist.

Basically, a user places an order using their wallet by interfacing with the website, or or trading programmatically using the API. The platform will then relay this information to the Ethereum blockchain through the 0x protocol and the the latter uses smart contract to complete the order on the blockchain.

As a relayer, it crafts order book from cryptographically signed messages from liquidity providers or market makers who are willing to sell their assets for a given time period. A liquid taker or market taker accesses the order book and agrees to trade with the maker under specific conditions. The order is then filled through the 0x protocol.

You can also contact the company for automated trading and dApp integration via API.

BarterDex

BarterDex is a DEX that uses atomic swaps, which is a smart contract technology that enables two parties (in different cryptocurrency chains) to exchange different cryptocurrencies or tokens without anyone defaulting.

Being a product of Komodo platform, BarterDex had transacted more than 60,000 atomic swaps by June 30 this year. However, it is still in beta and has recorded very low trading volumes on most instruments. The exchange allows trading of all cryptocurrencies against Komodo network. It also does not allow fiat transactions and hence is not the best place if you are new to cryptocurrencies. It also does not offer margin trading. It offers advanced charting for cryptocurrencies as well as history and balances.

The DEX lists more than crypto assets pairs. However, the platform will list 1000 cryptocurrencies once it fully integrates the ERC20 tokens. The fees is around 0.15% per trade for takers while it is free for makers. This is low compared to the fact that most exchanges charge between 0.2% - 0.25% per trade.

The DEX works best with the Komodo’s Agama wallet because you do not have to download a full node on the computer, but you can also use Agama Wallet App, you can use Komodo Paper Wallet (Cold Storage) or Ledger Nano S.

The bad side is that the cap on crypto-to-crypto transactions is 1 BTC while fiat-crypto transactions capped below 1 BTC, and private transactions could draw attention of regulators.

Stellar Dex

Stellar Dex has just released its long-waited decentralized exchange. The platform is a decentralized cryptocurrency exchange. It allows users from different blockchains to trade cryptocurrencies. Unlike most DEXs which are limited to Eth-based tokens, Stellar Dex allows trading of BCH, BTC, USD, ETH and much more although it is a heavily centralized cryptocurrency. It also allows depositing of fiat that you can use to trade.

You can also withdraw the cryptocurrency from your wallet into a different exchange wallet at a fee. For instance, using Lumens, the platform allows a user from one blockchain with EUR balance to trade with another with USD balance all without any need for conversions. It matches the two orders based on Lumens.

The advantage of this is that those with fiat do not need to convert them into Lumens or any other cryptocurrencies to participate in trade when they only need a different fiat currency on a cryptocurrency exchange. It also allows users to keep their digital assets in whichever currency they will because it is easy to make the conversion.

Other wise, the platform is basically a matching order system that completes a taker order when a matching maker order is made. The order will cancel when a matching order is not found. A user can also look on the order book to select the best rate of conversion for his or her assets at any time.

The transaction volume on this crypto exchange is $377,825 USD. The blockchain was also planning to add Lightning Network support.

It allows users to create digital assets including currency, commodity, security, utility token, or other type of asset.
