Before You Begin

To run a policy across two instances you need at least four users, as described below. Verra operates in this case as the main instance, while other instances operate as the dependent instances.

User	Where	Purpose
Main standard registry	Main instance	Owns and publishes the policy.
Remote user	Main instance	A local copy of the user created in a dependent instance. Holds the imported decentralized access key.
Dependent standard registry	Dependent instance	Approves the imported remote policy so local users can run it.
Dependent user	Dependent instance	The project developer or VVB who requests access, registers for the policy, submits projects, etc. to the remote policy.

You also need a policy that is ready to publish, or already published. This guide uses the VM0047 methodology published on the Verra’s UAT environment using the Hedera testnet (public link: 1785511586.942929104).

Figure 1. The Verra Portal. VM0047 in the first row is installed but not published yet.

Tip: Take note of the public link and, later, of the decentralized access key as you work through the setup. Both values are needed again at later steps.
