Pay Hook

What everyone needs to know

• A pay hook contract provides extensions to a treasury that augments the default JBMultiTerminal behavior.
• Pay hooks include a custom afterPayRecordedWith(...) hook that executes after all default protocol pay logic has successfully executed in the terminal contract. The hook is passed contextual information via a JBAfterPayRecordedContext data structure.
• Each IJBTerminal fork can leverage pay hooks in unique ways.

What you'll want to know if you're building

• Pay hooks must adhere to the IJBPayHook interface.
• The ruleset's dataHook specifies the active pay hook contract.
• The IJBPayHook's afterPayRecordedWith(...) hook is triggered in JBMultiTerminal._pay(...).
