🎯 Concentrated Liquidity Market Maker CLMM
A type of automated market maker where you supply your liquidity only inside a price range you choose, instead of spreading it across every possible price. While the price stays in your band, your money fills trades and earns fees.
🛣️ The simple version — a food stall on the busy block
Picture a food vendor with a fixed number of stalls. An older market maker rents stalls evenly along an entire 100-mile highway, just in case customers show up anywhere. Almost every stall sits empty. A CLMM vendor instead puts all their stalls on the one busy downtown block where the crowd actually is, serving far more people with the same number of stalls. The catch: if the crowd moves to a different neighborhood, those stalls suddenly serve no one. That trade-off is the whole idea of concentrated liquidity.
🧩 How a CLMM actually works
In an older AMM like Uniswap V2, a liquidity provider's funds are spread evenly across every price from zero to infinity, so most of the money sits idle at prices that almost never trade. A CLMM lets you pick a band instead, for example "provide ETH/USDC liquidity only between $2,000 and $3,000," and all your capital is concentrated there.
The price line is split into tiny discrete steps called ticks (or bins), typically about 0.01% (1 basis point) apart, though the exact spacing varies by pool and fee tier. The space between ticks is where your liquidity lives. While the market price stays inside your band, your money fills trades and you earn fees in proportion to your share of that band.
📉 What happens when price leaves your range
Once the price moves outside the band you chose, your position goes idle. It stops earning fees, and it ends up fully converted into just one of the two assets, the one that is now worth less. You then have two choices: wait for the price to come back into your range, or rebalance into a new range around the current price. This is why a CLMM rewards attention rather than "set and forget."
⚖️ Why people use it, and what it costs
| Upside | Trade-off |
|---|---|
| 🎯 Capital efficiency — concentrating in the active band can be far more efficient (Uniswap cited up to about 4000x vs V2 for tight ranges) | 📉 Impermanent loss is amplified; reports note it can run roughly 3.4x higher than V2 even for a fairly wide range, and worse for narrow ones |
| 💧 Deeper liquidity near the current price means better prices and lower slippage for traders | 🛠️ It demands active management; a position outside its range earns zero fees |
📊 The "4000x" and "3.4x" figures are headline numbers for specific range widths. Treat them as what can happen, not what always happens.
🚪 Where a beginner meets it
You meet a CLMM the moment you try to "provide liquidity" on a modern decentralized exchange and it asks you to pick a price range. That range selector is the CLMM. The model was introduced by Uniswap V3, launched in May 2021, to fix the "lazy liquidity" problem of older AMMs where most capital sat idle. Today it also powers Raydium CLMM and Orca Whirlpools on Solana.
❓ FAQ
- Is concentrating my liquidity just free extra yield?
- No. A tighter range can earn more fees, but it also amplifies impermanent loss and needs active management. If the price leaves your range you earn zero fees and your position fully flips into just one of the two assets. CLMM rewards attention, not 'set and forget.'
- What happens when the price moves outside my range?
- Your position goes idle and stops earning trading fees. It also ends up fully converted into just one of the two assets. You then wait for the price to come back into your range, or you rebalance into a new range.
- What are 'ticks' in a CLMM?
- The price line is split into tiny discrete steps called ticks (or bins), typically about 0.01% (1 basis point) apart, though exact spacing varies by pool and fee tier. The space between ticks is where your liquidity is actually deployed.
- Where did CLMMs come from?
- The model was introduced by Uniswap V3, launched in May 2021, to fix the 'lazy liquidity' problem of older AMMs where most capital sat idle. It is now used by Raydium CLMM and Orca Whirlpools on Solana, among others.
