Rehive consists of three parts: Platform, Extensions, and Applications. This overview assumes that you are familiar with these.

In this guide we will look at dive into what a Currency Manager is, how to build a Currency Manager Extension as well as some more advanced Currency Manager implementations.

The first place to start is by familiarizing yourself with the Get Started section. This gives a basic overview of how to start building an extension as well as the ground-level endpoints you’ll need to use. You should also familiarize yourself with Rehive’s Standard Configurations to ensure that the correct subtypes are used for specific transactions.

Lastly being comfortable with the transaction and transaction collection logic is also required to start building a currency manager extension.

What is currency management?

Currency management allows each Rehive currency to be controlled by a service user. This user is known as the currency manager and is the sole entity that can shift transactions of that currency to a Complete or Failed state.

The manager is assigned to the currency by updating the manager field using the service user’s ID as the input. See the Core API doc section for more information.

What is a currency manager extension?

A currency manager extension is the status controller for a specific currency’s transactions on Rehive. It is also the link between the Rehive ledger and a third party ledger/store of value.

Its primary functions are to transition Rehive transactions from a Pending state to either a Complete or Failed state, as well as trigger any third party side effects required on the external third party ledger.

Transitioning transactions on Rehive as a currency manager is done by approving or declining transition events triggered by Rehive while it processes a transaction.
