LRC is a token that runs on the Ethereum blockchain. Ethereum supports the creation of an unlimited number of tokens, and LRC is one of many. These tokens are called ERC-20 tokens. Loopring, confusingly, is also the name of the company that creates a wider ecosystem around the protocol (also called Loopring), including a decentralized exchange called—you guessed it—Loopring. These tokens can be held in the company’s proprietary wallet, Loopring Wallet. This is a self-custodial wallet from which you can interact with the Loopring exchange.
