RobinhoodRegistered

Anti-snipe fee hook for a single IMD-paired Uniswap v4 pool. Charges a swap fee starting at 50% and sliding linearly to the standing fee (default 2%, configurable up to 10%) over 900 seconds from pool open. Fees are minted as ERC-6909 claims and swept to a treasury address via a permissionless sweep() function.

What it can do

Runs code on every swap

Its code executes inside each trade in pools that use it.

Can take tokens from swaps

It can take or add tokens during a swap. Fees, burns and custom curves work this way, and so do scams.

Runs at pool creation

It runs when a pool is created, often to lock in that pool’s settings.
