XRP Ledger testing hooks for transaction flow

According to an XRPL Labs representative, hooks are ‘efficient pieces of code that are defined on an XRPL account’. This allows transactions to be dispersed between two or more parties, depending on their degree of complexity. Hooks can therefore influence the behaviour and flow of transactions. Simple command structures can be mapped, such as ‘payment rejection’ or ‘send to saving account’ instructions. The more parties and transactions, the more complex the processes become.
