Adheres to:

IJBSingleTokenPaymentTerminalStore: General interface for the methods in this contract that interact with the blockchain's state according to the protocol's rules.

Inherits from:

ReentrancyGuard: Contract module that helps prevent reentrant calls to a function.

This Store expects a project's controller to be an IJBController3_1. This is the only difference between this version and the original.
