About

Loopring is an open protocol for building scalable non-custodial exchanges on Ethereum. Leveraging zero-knowledge proofs (zkRollup), it allows for high performance trading (high throughput, low settlement cost), without sacrificing Ethereum-level security guarantees. Users always maintain 100% control of their assets throughout the trade lifecycle. You can trade on Loopring to test it out. Loopring is an open-sourced, audited, and non-custodial exchange protocol, which means nobody in the Loopring ecosystem needs to trust others. Cryptoassets are always under users' own control, with 100% Ethereum-level security guarantees. Loopring powers highly scalable decentralized exchanges by batch-processing thousands of requests off-chain, with verifiably correct execution via ZKPs. The performance of underlying blockchains is no longer the bottleneck. Loopring performs most operations, including order-matching and trade settlement, off the Ethereum blockchain.

Pros & Cons from Real Users

Pros

  • I didn't really like anything. May be the fact that you changing tokens on l2 is gas free a plus
  • It was very easy to link my wallet with the MetaMask extension in Chrome. Then you can trade without paying the gas fees. It only cost $0.40 per trade which is considerably cheaper than gas fees right now.

Cons

  • It doesn't work with any WalletConnect compatible dapp except for their own website.
  • Nothing really. Interface is basic but this is a beta. The high cost for setting up their L2 wallet is off-putting but that is because of the current gas fee on L1 network.
