What is Loopring (LRC)?
Quick Facts
- Founded: 2017 by Daniel Wang in Shanghai
- Token: LRC, native ERC-20 token of the Loopring protocol
- Blockchain: Ethereum (Layer 2 via zkRollup)
- Max Supply: ~1.374 billion LRC tokens
- Key Use Cases: fees, staking, governance, liquidity rewards
- Protocol Type: Open-source, non-custodial DEX infrastructure
- ICO: Raised approximately 120,000 ETH in 2017
Introduction
Loopring is an open-source Layer-2 protocol built on Ethereum that enables fast, low-cost, and secure decentralized exchange (DEX) trading. It uses zero-knowledge rollup (zkRollup) technology to process thousands of transactions off-chain while settling final proofs on Ethereum mainnet.
By combining the speed of centralized exchanges with the security of decentralized settlement, Loopring aims to make non-custodial trading practical and affordable for everyday users.
History & Background
Loopring was founded in 2017 by Daniel Wang, a software engineer previously employed at Google, Boston Scientific, and JD.com. The project held an ICO that year, raising around 120,000 ETH.
The LRC token was first distributed publicly in August 2017. The flagship protocol built on Ethereum officially launched in 2019, marking one of the earliest production-grade zkRollup deployments in the industry.
How Loopring Works
At its core, Loopring is a zkRollup: thousands of trades and transfers are bundled together and processed off-chain. A cryptographic proof known as a zk-SNARK verifies the correctness of all these transactions without revealing their contents.
Only this compact proof and essential summary data are posted to the Ethereum mainnet. This design inherits Ethereum's security while dramatically reducing costs and increasing throughput compared to on-chain Layer-1 transactions.
Loopring supports both order-book and automated market maker (AMM) models, giving it a hybrid approach unique among DEX protocols.
Tokenomics
LRC is the native ERC-20 token with a maximum supply of approximately 1.374 billion tokens. Token distribution from protocol fees is allocated as follows:
- 80% goes to liquidity providers
- 10% funds the protocol insurance pool
- 10% is directed to the DAO community treasury
A portion of protocol fees is used to buy back and burn LRC, introducing a deflationary pressure over time.

Ecosystem & Use Cases
LRC powers multiple layers of the Loopring ecosystem. It is used to pay transaction fees, stake in the protocol for rewards, and participate in governance decisions through the Loopring DAO.
Liquidity providers earn LRC rewards for supplying assets to trading pools. The protocol also introduced a smart contract wallet and NFT support, expanding its reach beyond pure token trading.
Team, Governance & Community
The Loopring Foundation, a non-profit based in Shanghai, oversees protocol development. Daniel Wang serves as its CEO and continues to guide the technical roadmap.
Governance is handled through the Loopring DAO, where LRC holders vote on protocol upgrades and the use of community treasury funds. The community is active across Telegram, Twitter, and Discord.
Advantages
- Low fees: zkRollup batching cuts transaction costs dramatically versus Layer-1 Ethereum.
- Self-custody: Users retain full control of their assets at all times.
- Hybrid DEX model: Supports both order-book and AMM trading for flexibility.
- Ethereum security: Inherits the security guarantees of the Ethereum mainnet.
- Pioneer status: One of the earliest and most battle-tested zkRollup implementations.
Risks & Challenges
- Declining TVL: Total value locked in the protocol has trended downward amid intense Layer-2 competition.
- Competition: Newer Layer-2 networks like Arbitrum, Optimism, and zkSync have captured significant market share.
- Wallet sunset: The Loopring smart wallet was announced to be discontinued, narrowing the product suite.
- Adoption risk: Protocol success depends on exchange builders choosing to build on Loopring.
Long-Term Vision
Loopring envisions a future where decentralized, non-custodial exchanges are the default for crypto trading — as fast and intuitive as centralized platforms, but without trust or custody risks. As zero-knowledge cryptography matures and Ethereum's ecosystem expands, Loopring aims to remain a foundational piece of infrastructure enabling secure, scalable on-chain finance.
Frequently Asked Questions
- What is Loopring (LRC)?
Loopring is an open-source Layer-2 protocol on Ethereum that uses zkRollup technology to enable fast, low-cost, and non-custodial decentralized exchange trading. LRC is its native token used for fees, staking, and governance.
- What is a zkRollup and why does Loopring use it?
A zkRollup bundles thousands of transactions off-chain and generates a cryptographic proof verifying their validity, which is then posted to Ethereum. This allows Loopring to offer high throughput and low fees while inheriting Ethereum's security.
- Who founded Loopring?
Loopring was founded in 2017 by Daniel Wang, a software engineer with prior experience at Google, Boston Scientific, and JD.com. The Loopring Foundation, a non-profit based in Shanghai, oversees ongoing development.
- What is the LRC token used for?
LRC is used to pay transaction fees on the protocol, stake for rewards, and participate in governance through the Loopring DAO. Liquidity providers also earn LRC rewards for supplying assets to the platform.
- What is the total supply of LRC?
The maximum supply of LRC is approximately 1.374 billion tokens. A portion of protocol fees is used to buy back and burn LRC, reducing supply over time.
- How does Loopring differ from other DEX protocols?
Loopring stands out by supporting both order-book and AMM trading models in a hybrid approach, whereas most DEXs rely solely on AMMs. It is also one of the earliest and most established zkRollup protocols on Ethereum.
- What risks does Loopring face?
Loopring faces growing competition from newer Layer-2 networks such as Arbitrum, Optimism, and zkSync, which have attracted significant liquidity and developer activity. Declining total value locked (TVL) and the sunsetting of its smart wallet are also challenges.
- What is the Loopring DAO?
The Loopring DAO is the decentralized governance body where LRC token holders vote on protocol upgrades and decide how to allocate the community treasury. It receives 10% of protocol fee revenue for this purpose.
