Loopring Subgraph
A Layer 2 decentralized exchange protocol built on zkRollup technology for scalable, low-cost Ethereum trading and NFT minting.
Overview
Loopring Protocol is a Layer 2 decentralized exchange (DEX) protocol built on Ethereum using zkRollup technology. It enables scalable, secure, and low-cost trading and NFT minting by processing transactions off-chain while maintaining Ethereum-level security. Loopring offers a full-stack solution including APIs, SDKs, and smart contracts that allow developers to build decentralized trading platforms, wallets, and NFT marketplaces with instant transaction finality and gas fees up to 100 times lower than Ethereum mainnet. The protocol supports programmatic trading, NFT creation, and wallet management with features like social recovery and two-factor authentication.
Designed primarily for DeFi developers, NFT platform builders, and infrastructure teams, Loopring simplifies integration with its comprehensive documentation and developer tools. Users can connect wallets, mint NFTs, trade tokens, and participate in yield-earning programs on Layer 2 without sacrificing security or decentralization. Loopring’s zkRollup approach batches multiple transactions into a single proof submitted to Ethereum, reducing congestion and costs while preserving trustlessness.
What sets Loopring apart is its combination of zkRollup scalability with a user-friendly wallet and DEX interface, enabling seamless onboarding and interaction with Layer 2 DeFi and NFT ecosystems. Its open APIs and SDKs facilitate custom dapp development and token listing. Loopring has attracted over 100,000 users and powers a growing ecosystem of decentralized applications. Developers can get started by exploring the official SDKs, APIs, and smart contract references, with active community support and ongoing protocol upgrades ensuring a robust platform for scalable decentralized trading and NFT minting.
