Loopring itself is not an exchange, but it is a platform that can help decentralized exchanges use their code.
With the Loopring protocol, you don't need to depend on centralized exchanges to safeguard your assets. Loopring prevents you from sending your cryptocurrencies from your wallets to centralized exchanges. Centralized exchanges are susceptible to hackers. The Loopring protocol helps you save cryptocurrencies in your wallet and trade them without sending them anywhere. Smart contracts will help you trade using Loopring tokens to automate your order when the right price is hit.
