AMM core & periphery

BarkSwap's concentrated-liquidity AMM is a Uniswap v3-style design with a single dynamic-fee pool per pair (no fixed fee tiers). This page lists the entry points most integrations use; for full interfaces see bark_contracts/contracts/src/.

Function	Description
poolByPair(address tokenA, address tokenB) → address	The default pool for a pair (address(0) if none).
createPool(address tokenA, address tokenB) → address	Create a default pool for a pair.
defaultCommunityFee() → uint16	Protocol fee share applied to new pools.

Pool

Created per pair. Holds liquidity and executes swaps; usually accessed via periphery.

Member	Description
globalState() → (uint160 price, int24 tick, uint16 fee, ...)	Current price (sqrtPriceX96), tick, and dynamic fee.
tickSpacing() → int24	Tick granularity — position ticks must be multiples of this.
liquidity() → uint128	Currently active in-range liquidity.
Events	Swap, Mint, Burn, Initialize — indexed by the BarkSwap backend.

Key differences from Uniswap v3

• No fee tiers. A pair has one default pool with a dynamic fee; calls take a deployer address (address(0) for default) where Uniswap takes fee.
• Encoded paths pack addresses only — no fee bytes between hops.
• globalState() replaces Uniswap's slot0().
