Concentrated liquidity

Concentrated liquidity was introduced natively in Uniswap v3, whose whitepaper appeared in March 2021 and reached mainnet in May 2021. The price range is discretized into ticks, where each tick represents a 0.01 percent move, and the tick spacing is coupled to the pool fee (0.05 percent fee, spacing 10; 0.30 percent fee, spacing 60; 1 percent fee, spacing 200). When price moves outside a provider's range, the position sits entirely in one of the two assets and stops earning fees until price returns.

The model matters because it allows the same trading volume with far less capital locked, reduces slippage for traders and enables active market-making strategies. In return it demands continuous management, exposes the provider to amplified impermanent loss and forces position rebalancing, tasks that usually fall to professional providers or automated managers. Positions are no longer fungible and are represented as NFTs under the ERC-721 standard, unlike the fungible liquidity tokens of earlier versions.

The approach has spread well beyond its origin. Uniswap v4 keeps concentrated liquidity and adds hooks, while PancakeSwap v3 and Trader Joe's Liquidity Book (with price bins) are variants of the same idea. Managers such as Gamma, Arrakis and Bunni automate rebalancing for providers who prefer not to handle it manually. In the European Union, liquidity providers should assess the tax and regulatory treatment of these positions according to their profile.
