What Loopring Means to Relayer Developers

What Loopring Means to Exchanges

Loopring is open sourced and offers open participation. Anyone can become a DEX with our software: you can join our DEX network to share liquidity, or create and manage your own DEX network. Sharing liquidity greatly improves your competitive advantage.

  • Loopring is risk free and low cost

    Loopring is risk-free and low-cost as relayers don’t hold users’ assets. You can match orders without asset reserves, lowering barriers to entry.

  • Crypto-tokens and provide more liquidity

    Alternatively, run a relayer while owning token reserves and provide extra liquidity by adding your own orders, earning more money as a market-maker in the process.

  • No effect to the assets of you or your users

    Noncommital and nonbinding. As a participant in the Loopring ecosystem, you can stop at any time, without impacting your or your users' assets.

Loopring Brings New Revenue

  • Loopring Brings New Source of Income

    Loopring incentivizes wallets with at least 20% of the trading fee on all orders they generate - in real time.

  • Loopring Brings New Source of Income

    Setup and run a relayer, earning 80% of the trading fee on matched orders, risk-free and guaranteed by the protocol.

  • Loopring Brings New Source of Income

    Provide market making services, earning the spread plus rebate incentives, making even more money.

Why Protocols Matter?

  • The Loopring protocol is blockchain agnostic

    The Loopring protocol is blockchain agnostic, and can be deployed on any blockchain with smart contract capability.

  • The Loopring protocol also hides the implementation details

    The Loopring protocol hides the implementation details of the underlying blockchain and offers a high level abstraction to make building DEXs much easier.

  • Loopring creates a unified trading experience for users

    Crucially, Loopring creates a unified and networked trading experience for users, breaking down siloed liquidity pools. Shared standards means greater growth.

  •  AI-based smart agents/robots to trade tokens without human assistance

    Loopring makes it possible for AI-based smart agents/robots to trade tokens without human assistance. This is key for the future economy where AI-based automatons will think, own, trade, and evolve.

How Loopring Works

  • Letting users create orders from their own wallets

    Loopring works by letting users create orders from their own non-custodial wallets. These orders are signed with users' private keys but do not hold assets captive nor require token deposits.

  • Build customizable order-books

    Orders are then sent to one or more relayers, or shared in a liquidity sharing network, to build customizable order books and to identify tradable order-rings.

  • Atomic transfers of tokens, higher trading speeds, and zero-risk

    Order-ring settlements are completed on-chain using Loopring protocol smart contracts, which guarantees risk-free atomic transfers of tokens.
