Loopring (LRC) is a decentralized based protocol based on the Ethereum blockchain. Its main aim is to allow individuals to trade broadly across different exchanges. This means it can offer liquidity to anyone trying to access the cryptocurrency market at large. Loopring was created in August 2017 by Daniel Wang as a response to centralized exchanges as they were starting to lack in terms of financial transparency and reliable security.
To make an online trade, users place orders through the loopring.io wallet. These submitted orders are submitted to the Loopring network and forwarded to the smart contracts and off-chain relay nodes. Ring minors ensure that these orders can be filled, they are compensated for helping organize the ring of orders. They do this through a fee payable in LRC or a deduction from the total crypto amount.
The Loopring Exchange is a Decentralised Exchange (DEX) that runs on the Ethereum blockchain. The Loopring Exchange, unlike other DEXs, is based on the layer-2 Loopring zkRollup protocol.
The exchange was the foremost DEX to be deployed on the system in February 2020, and it was built of the layer-2 scaling solution. The layer-2 exchange, which allows customers to trade through an automated market maker (AMM) and order book trading system, offers exceptionally reduced gas fees and greater speed without sacrificing security. Users can benefit from minimal fees while preserving custody of their digital assets, thanks to the adoption of zkRollup protocols.
While the Loopring Exchange is primarily focused on exchanges, it also serves as a payment application, allowing users to send ERC-20 tokens or ETH to any Ethereum address via the layer-2 network for a modest fee.
On Ethereum, “zero-knowledge rollup” zkRollup is a form of layer-2 scaling solution that allows for substantially higher throughput and reduced costs while maintaining security. It accomplishes this by offloading all of the heavy lifting (computations) off-chain while maintaining rule enforcement and security through using validity proofs, which are cryptographic proofs that attest to what occurred off-chain.
zkRollups inherit the same non-custodial security as Ethereum. Still, they can run significantly faster because Ethereum verifies these proofs and keeps sufficient data to tell precisely which off-chain accounts own what.
Before you begin to use Loopring exchange, you must connect to the layer-2 network. To do this, you’ll need a web 3.0 digital wallet; an excellent example of this is MetaMask. MetaMask is a digital wallet used for storing Ethereum and other ERC-20 tokens. It’ll connect your crypto assets and the dApps.
To begin using Loopring exchange, you need to port from layer 1 (where your crypto assets are-Ethereum) to layer 2 (where Loopring is). Deposits and withdrawals of digital assets do not require a gas fee on layer-2 networks, unlike layer-1 networks like Uniswap.
Once you’ve paid the initial gas charge for your deposit, your digital assets will be stored on the gas-free network until you’re ready to withdraw them. Follow the steps below to get this done.
You’re ready to start exchanging once you’ve deposited funds into your Loopring layer-2 wallet. The deposits you make in the layer-2 network are mapped to the Loopring Merkle tree. This means that if something happens to the Loopring network, the assets can be retrieved.
Loopring supports trading using order books and automated market maker. Here is a guide on how to use AMM.
Once the exchange is complete, the crypto will reflect in your layer 2 wallet.
As mentioned earlier, you can also choose to use an order book to exchange. Order books are common with CEX, you don’t see them on DEX. Here is a quick guide.
The benefit of order books on exchanges is that it allows users to place limit orders. When a user specifies a price at which they want to buy or sell, limit orders are created. The order will remain available on the order book until it is filled by another trader. Makers are people who place open orders on the market, allowing liquidity to flow.
The Loopring Exchange AMM uses liquidity pools to provide smart contract cryptocurrency exchange. Liquidity can be made available to liquidity pools, which are then utilized by traders. As a reward for taking risks, liquidity providers receive 0.20 percent of all trades completed through the AMM.
When an investor withdraws funds, the collected fees are added to the liquidity pool and claimed. To join the liquidity pool as a liquidity provider, a user must deposit equal amounts of both assets. Follow this guide if you would wish to provide liquidity.
As a reward for providing liquidity, users will get a liquidity provider token minted by the exchange.
