The Loopring protocol is a chain-independent layer two scaling solution designed specifically to facilitate decentralized exchanges (DEXs) and payment systems. It currently works with Ethereum, NEO and Qtum blockchains. With this in mind, DeFi is one of the vital infrastructures supporting the web. Technically, this is an open source automatic token exchange protocol. It also runs on a highly efficient, unattended, decentralized and secure protocol system. The Loopring design also provides protection against front-run, Sybil attacks, distributed attacks, and other types of fraud. Since payments and trading are two core and resource intensive activities. The Loopring protocol is likely to see integrations with major exchanges and wallets in the coming days due to high Ethereum traffic / increased demand and therefore the need for additional block space.
