Radar Relay is an innovative crypto trading service that allows users to exchange ERC-20 tokens directly from their wallets, without giving any private keys. As the exchange is in beta version, it still does not charge any fees, except gas.
Basically, Radar Relay is intended for advanced crypto traders who are keen on Ethereum and the other ERC-20 tokens. You cannot deposit any fiat currency on this platform, nor buy Bitcoin or Ripple on this exchange.
