Loopring

Spin up high-speed trading and payments without giving up your keys. Loopring gives you a practical stack to move, trade, and build on Ethereum’s layer 2 with the responsiveness users expect and the safety of assets held by smart contracts on layer 1.

For individuals, getting started is straightforward: connect a wallet, activate your L2 account, and move funds from mainnet once. From there, place limit or market orders on an order book with near-instant confirmations and tiny fees. Create, edit, and cancel orders in real time, watch partial fills settle automatically, and track performance with built-in histories. Need to send money? Share a payment link or QR code and transfer tokens in seconds, even during market congestion. You can group multiple transfers into a single batch to cut costs further, export CSVs for taxes, and withdraw back to L1 whenever you want.

For teams launching an exchange, the workflow is pragmatic: deploy your front end, connect to Loopring’s REST and WebSocket endpoints, and run or integrate with a relayer to handle order intake and settlement. Define pairs and tick sizes, set fees and maker/taker rules, and brand the interface to match your product. The protocol bundles activity into batches proven by succinct cryptography and finalized on Ethereum, so your venue scales without compromising user custody. Add wallet integrations, implement webhooks for trade and transfer events, and wire up monitoring for batch status, balances, and proof submissions. Start on testnet to iterate quickly, then switch config to mainnet when you’re ready. more
