GreenlineBuybackHook

RobinhoodRegistered

After each swap, skims a configurable buyback share from the unspecified currency: token-side skims are burned immediately, quote-side skims accrue for a permissionless executeBuyback() that swaps quote back into the token and burns the proceeds. Pool initialization is gated to factory-registered pools only via beforeInitialize.

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.
