Concentrated liquidity from a swapper's perspective

Concentrated liquidity lets providers make their capital available within selected price ranges. A swap consumes the combined liquidity active along its execution path. It does not trade against every deposited token as though all reserves were available at every price.

Several positions become one execution curve

Suppose one hypothetical position is active between prices 1 and 2, and another between 1.5 and 3. Around 1.7, both contribute. Around 2.5, only the second contributes. The swapper sees the combined effect rather than selecting an individual provider.

Uniswap's v3 introduction explains how individual ranges form a combined curve. Its concentrated-liquidity concepts describe active range behavior.

The trade can encounter different conditions

A small order may remain within a region containing substantial active liquidity. A larger order can move beyond that region and encounter a different set of positions. The output curve can therefore change character during one execution.

The router needs enough state to model those transitions. A reserve total by itself cannot describe where liquidity begins or ends. This is a structural point about the pricing model, separate from measuring a pool's current depth for a specific live order.

Range boundaries are not personal orders

A provider's range endpoint does not mean the swapper has chosen a separate maker order at that level. The pool aggregates position contributions according to its rules. A single trade can cross several boundaries while remaining one pool swap.

Concentration can make liquidity dense where providers place it, but it can also leave other regions sparse. The design does not promise that the current price will remain within a dense range or that providers will keep the same allocations.

When reading a route, distinguish a change of pool from a change of active liquidity inside one pool. Both can affect execution, but only the first necessarily represents an additional venue or hop. That distinction prevents overcounting the number of exchanges in a concentrated-liquidity transaction.
