Coin98 will guide you on how to use Loopring Exchange with its core features: trade & swap. Let's find out all detailed information here!

The DeFi space of crypto is growing at a staggering pace. Among them, Ethereum is one of, if not the most developed ecosystem at the moment. As the blockchain grows, some serious problems regarding the scalability and transaction throughput emerge. That is when the application of Loopring comes in.

In this article, I will give you the clear instructions on how to use Loopring Exchange to trade assets by using both the AMM and Orderbook model.

Loopring Overview

Loopring started as a modular protocol that provides the infrastructure for DEXs to build on in order to maximize the liquidity and throughput. Loopring adopts the usage of zkRollup (Zero-knowledge Rollup) - an Ethereum Layer 2 Scaling Solution.

However, Loopring developed not only a framework for multiple DEXs, but also a DEX of their own. The Loopring Exchange includes a non-custodial AMM as well as an Orderbook exchange.
