What it does

Every swap in this single WIF/Stock Token pool pays a fixed extra 0.5% (about 0.8% total with the 0.30% LP fee), which is burned if in WIF or sent to the floor backing contract if in the Stock Token, while LPs keep full freedom to add and withdraw liquidity.

How it works step by step

  • Serves exactly one pool: WIF paired with a SPY Stock Token, with a 0.30% LP fee and tick spacing 60; any other pool setup is rejected.
  • Charges an extra 0.5% hook fee on every swap, taken from the unspecified side (the output for exact-input swaps, the input for exact-output swaps).
  • If the fee is in WIF, it is burned, which reduces WIF supply.
  • If the fee is in the Stock Token, it is sent directly to a fixed floor (backing) contract.
  • Has no owner or admin, and LPs can add and withdraw liquidity freely.
Swap behaviour
After each swap the hook takes 0.5% of the unspecified side. Exact-input traders receive 0.5% less output, and exact-output traders pay 0.5% more input. WIF fees are burned and Stock Token fees go to the floor contract.
Liquidity behaviour
No liquidity callbacks; LPs can add and withdraw freely.
Fee behaviour
Traders pay a fixed 0.5% hook fee on top of the pool's static 0.30% LP fee, so about 0.8% in total. The hook fee is burned when it is in WIF or sent to the immutable floor address when it is in the Stock Token; the 0.30% goes to LPs.
Owner & admin controls
No admin controls found.

Enabled Uniswap v4 callbacks

beforeInitialize, afterSwap, afterSwapReturnDelta

beforeInitialize: locks the hook to the single WIF/Stock pool with a 0.30% fee and tick spacing 60; afterSwap: calculates the 0.5% fee and burns it or sends it to the floor; afterSwapReturnDelta: charges that 0.5% to the trader's swap amount.

Security & trust assessment

Risk level: low (verified source, high confidence).

Who controls it: No one holds privileged keys. Every parameter, including the floor recipient, is fixed when the contract is deployed.

Risk to user funds: The hook only takes a fixed 0.5% of each swap's unspecified amount, which is either burned or sent to the floor contract. LP principal cannot be locked or drained.

Security findings

  • [info] Fixed 0.5% swap fee: The hook fee is a hard-coded constant of 0.5% of the unspecified swap side. No one can change it.
  • [info] Immutable, ownerless contract: The pool manager, floor address, WIF and Stock Token addresses are all set permanently at deployment. There is no owner, and the hook keeps no tokens between swaps.
  • [info] Unrestricted LP withdrawals: The remove-liquidity callbacks are disabled, so the hook can never block or charge LP withdrawals.
