Compared to Uniswap

​

The short answer

The core is a port of Uniswap V3 — rewritten for modern Solidity and verified against Uniswap’s own compiled bytecode. On top of that base sits a typed hook system, which is the capability people reach for V4 for, plus pieces no Uniswap version has: a native StableSwap curve, on-chain limit orders, and a no-fee-tier market structure.

What this means in practice

For traders — one canonical pool per pair means depth is never split across fee tiers of the same market, and the fee adapts to volatility instead of being whichever tier the LPs happened to pick. For LPs — V3-style concentrated positions where you want efficiency, V2-style full-range where you want simplicity, an amplified curve for pegged pairs — one venue, one interface. For integrators — the events are byte-identical to Uniswap V3’s, so existing subgraphs and indexers work unchanged; execution goes through the native periphery.

What it is not

It is not a Uniswap V4 deployment: V4 is a singleton with flash accounting; here every pool is its own contract with its own plugin, attached at creation and opted into hook by hook. The design goal was V4’s extensibility on V3’s battle-understood architecture — not V4’s architecture itself.
