At Sologenic.org you can easily track historical prices of the xrpl tokens you trade. You are also able to easily see the orderbook and your trade history.
When engaging with Sologenic you actually engage with the XRPLedger directly. Sologenic is an interface communicating with the xrpledger and there is no technical way for sologenic to access your wallet, the XRP-Ledger makes sure of that.
The Sologenic Decentralized Exchange is easy to use and we are here to make it even easier by providing tutorials and support.
