Overview
Loopring Exchange is a non-custodial DEX built on Ethereum Layer-2 using zk-Rollups. You keep custody while trades settle fast with tiny fees. The project started in 2017 with a goal to make on chain trading cheap, auditable and near instant.
What it is
Loopring routes activity through Layer-2 where transactions are bundled and proven before settling on Ethereum. This design cuts costs to fractions of a cent and boosts throughput. You trade from your wallet while an order book and AMM logic handle matching.
Why it matters
zk-Rollups compress thousands of actions into succinct proofs. That means speed and cost benefits without giving up Ethereum security. The model removes AMM slippage surprises and allows price and size control more like a centralized order book.
Standout features
- Hybrid matching with order rings and AMM mechanics for flexible execution.
- Ring miners who package orders and earn LRC incentives.
- Block Trade that taps CEX style depth while you remain self custodial.
Pros
- Ultra low fees and fast settlement on Layer-2.
- You control private keys and funds at all times.
- Order book style control with AMM flexibility.
- Access to deeper liquidity via Block Trade.
Cons
- Layer-2 setup can feel technical for new users.
- Order rings and ring miner concepts add learning curve.
- Token list is smaller than big centralized exchanges.
- Ethereum congestion can still affect final settlement rhythms.

Final take
Loopring Exchange shows how Layer-2 can deliver fast, low cost and self custodial trading with order book like control. It is lean and clever, with a bit of complexity for newcomers. For users who want speed and custody in one place, it is a strong example of Layer-2 done right.
