Hooks add programmable logic to the XRPL—executed when transactions affect an account:

// Conceptual overview - Hooks use WebAssembly, typically written in C

const hooksOverview = {
whatTheyAre: 'Small programs that run on transactions',
language: 'C compiled to WebAssembly',
trigger: 'Incoming or outgoing transactions',
