What is concentrated liquidity?

An automated market maker design that lets a liquidity provider commit capital to a chosen price range instead of the entire curve, earning far more fees per dollar while that range holds.

The older constant-product design spread a provider's capital across every price from zero to infinity, which meant almost all of it sat idle at prices the asset would never reach. Concentrating that same capital into a narrow band around the current price makes it many times more productive, and turns passive liquidity provision into an active job of re-ranging.

The point people miss is that it sharpens impermanent loss rather than removing it. Tighter ranges earn more fees and take more risk, and the two move together by construction.

How it works

A provider picks a lower and an upper price and deposits into that interval. Inside the range, the position behaves like an ordinary pool position and earns a share of the trading fees on volume that passes through it.

When price leaves the range, the position stops earning entirely and sits fully in one asset, specifically the one that has just performed worse. Above the range you hold only the quote asset, below it only the base. The position does not liquidate or expire, it simply goes inert until price returns or you move it.

Because positions are per-range rather than fungible, they are typically represented as individual positions rather than as a uniform lp token, which changes how they are tracked and how they are used as collateral elsewhere.

Fee tiers exist so that pairs with different volatility can charge appropriately. A stablecoin pair, where price barely moves, can support a very low fee and extremely tight ranges. A volatile pair needs a higher fee to compensate providers for a range that breaks often. The available tiers are set by each protocol.

Re-ranging costs gas and realizes the loss. Moving a position that has gone out of range crystallizes the divergence rather than avoiding it, so frequent rebalancing on an expensive chain can consume the fee advantage entirely.

Example

Illustrative. Two providers each deposit 10,000 dollars into an ETH pair currently at 3,000 dollars. One provides across the full curve. The other concentrates between 2,850 and 3,150, roughly plus or minus 5 percent. While price stays in that band, the concentrated provider might earn several times the fee income on the same capital, because their liquidity is far denser at the traded price. If price moves to 3,400, the concentrated position is fully in the quote asset and earning nothing, while the full-range position keeps earning at a lower rate. Neither outcome is a fee comparison alone, because the concentrated provider also absorbed the full divergence over that move.

Why it matters when you buy

As a buyer you never provide liquidity, but you trade against it. Concentrated liquidity is why a deep-looking pool can produce a bad fill on a large order, since depth exists only within active ranges and thins abruptly outside them. The liquidity pages measure realized spreads and depth per asset, which is the figure that decides what a purchase costs.

Questions

Is providing concentrated liquidity a way to earn yield?

It pays trading fees and carries market risk, so the return depends on price staying inside your range. RampAtlas does not advise on whether to do it, and describing it as a yield understates that the principal changes composition as price moves.

Why did my position stop earning?

Price left your range. The position holds entirely one asset until price returns or you re-range, and moving it locks in the divergence rather than reversing it.

Does this make trading cheaper for me?

It can, because dense liquidity near the current price reduces price impact for ordinary-sized trades. It can also make large trades worse, because depth falls away sharply once your order pushes past the concentrated band.
