What it does

A launchpad-style hook that gates pool creation and liquidity, takes ETH or USDG creation fees and a swap tip, and can alter swap amounts through return deltas, controlled by an owner with pause and payout powers.

How it works step by step

  • Registers new pools in beforeInitialize and tracks them via pool and seen mappings
  • Gates liquidity additions in beforeAddLiquidity with a band and spread check and a pause flag
  • Adjusts swaps in beforeSwap, using a return delta to take or supply currency
  • Accrues creation fees (ETH and USDG) and a tip, with a dev share and payees for distribution
  • Performs take and transfer operations through an unlock callback, with a reentrancy guard
Swap behaviour
beforeSwap enforces the pause flag and can return a delta via beforeSwapReturnDelta, so swap amounts may be adjusted and currency taken or supplied by the hook; the exact math is not fully determinable without source.
Liquidity behaviour
beforeAddLiquidity is implemented and gated by the pause flag and a spread/band check (BAND_HIGH, BadSpread, NoLiquidityHere errors); liquidity is also managed by the hook through pool accounting slots and an unlock callback that performs take/transfer operations.
Fee behaviour
Hook takes creation fees in ETH and USDG (creationFeeEth, creationFeeUsdg) and a tip (tipBps) and a dev share (devShareBps); the pool fee is a uint24 parameter set by the owner. Exact fee routing on swaps cannot be fully determined from decoded bytecode.
Owner & admin controls
Owner (Ownable, two-step transfer via transferOwnership/acceptOwnership, renounceOwnership) can set creation fees (setCreationFees), set dev address and dev share (setDev), set payees (setPayees), set tip bps and tick/fee parameters (0x4b0cae0a, 0xccfb5a81), pause and unpause swaps and liquidity (setPaused), and sweep funds via the sweeper/payout paths. Exact parameter semantics are not determinable without source.

Enabled Uniswap v4 callbacks

beforeInitialize, beforeAddLiquidity, beforeSwap, beforeSwapReturnDelta

beforeInitialize: validates and registers new pools with the hook. beforeAddLiquidity: gates or adjusts liquidity additions, enforcing pause and band constraints. beforeSwap: enforces pause and computes a custom swap path with beforeSwapReturnDelta, letting the hook take or supply currency. beforeSwapReturnDelta: the hook returns a delta that alters the amounts of the swap, so it can hold or move pool funds.

Security & trust assessment

Risk level: high, estimated (decoded bytecode, low confidence).

Who controls it: The owner can pause the hook, change fee and dev/payee parameters, set payees and redirect accrued balances, and may have sweep or payout powers over funds held by the hook. A compromised owner key could redirect protocol proceeds or block swaps and liquidity.

Risk to user funds: The hook has return-delta power on swaps and performs take and transfer operations through its unlock callback, so it can hold and move pool funds and accrued balances; pausing can block swaps and liquidity additions.

Security findings

  • [high] Hook takes custody of swap deltas: beforeSwapReturnDelta lets the hook take or provide currency during swaps, so the hook holds and moves pool value directly.
  • [medium] Owner pause and payee control: Owner can pause via setPaused and redirect payouts/payees via setPayees and payout, which can block trading or divert accrued fees.
  • [medium] Single owner key controls parameters: Ownable with two-step transfer; the proxy-free layout suggests no upgrade path, but owner keys are a single point of control.
  • [low] Adjustable fee parameters: Owner can set creation fees, tip and dev share, changing the economics for users without source verification.
  • [info] Unlock callback and reentrancy guard present: Contract includes a reentrancy guard and an unlock callback; behaviour depends on correct use of the pool manager unlock flow.
