DoubleSineHook
EthereumRegisteredCustom AMM hook managing two pools (ETH/TokenA and ETH/TokenB) sharing a single virtual ETH reserve via a proprietary constant-product curve (DoubleSineMath). The hook fully intercepts all swaps via beforeSwapReturnsDelta, bypassing Uniswap's native pricing. Charges a 1% buy/sell fee directed to an immutable treasury. Liquidity addition/removal is disabled; buy size is capped for the first 5 blocks post-initialization as an anti-snipe measure.
What it can do
Its code executes inside each trade in pools that use it.
It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.
It runs before liquidity is removed, so it can delay or refuse LP exits.
It checks every deposit before it goes in.
It runs when a pool is created, often to lock in that pool’s settings.
