# About Laminar

Laminar is the decentralized liquidity engine powering the Hyperliquid EVM ecosystem, designed to provide efficient and flexible trading on HyperEVM. Built on battle-tested protocols, Laminar offers both V2 and V3 liquidity pools to cover all AMM pool use cases.

## Concentrated Liquidity (V3)

* Provide liquidity within custom price ranges
* Significantly higher capital efficiency compared to traditional AMMs through concentrated liquidity
* Multiple fee tiers (0.05%, 0.3%, 1%) to suit different trading pairs
* Advanced position management with NFT representation
* Earn and collect LP fees without removing liquidity

## Classic Pools (V2)

* Simple, proven liquidity provision
* Fixed 0.3% fee structure
* Good for stable pairs and established trading pairs
* Earned LP fees directly reinvested into the pool

## Why Laminar?

* Efficiency: Maximize capital utilization with concentrated liquidity
* Flexibility: Choose between V2 and V3 pools based on your needs
* Security: Built on proven protocols with extensive testing and audits
* Integration: Deep integration with Hyperliquid's ecosystem
* Performance: Optimized for HyperEVM's high-performance environment
