In the Formance Ledger world, ledgers are logically separated from one another. There are occurences where you want to transfer value from one ledger to another. Fortunately for us, Flows provide a way to do this that takes care of the underlying details for us.

Workflow definition

---
stages:
# let's first provision a user account on our first ledger
- send:
    source:
      account:
        id: "world"
        ledger: "flows-demo-001"
    destination:
      account:
        id: "users:42"
        ledger: "flows-demo-001"
    amount:
      asset: "USD/2"
      amount: 100
# now let's transfer that value to our second ledger
- send:
    source:
      account:
        id: "users:42"
        ledger: "flows-demo-001"
    destination:
      account:
        id: "users:42"
        # note that we're sending to a different ledger
        ledger: "flows-demo-002"
    amount:
      asset: "USD/2"
      amount: 100

Running the workflow

Let’s save the above workflow to a file called ledger-to-ledger.yaml and run it: 
fctl orchestration workflows create ledger-to-ledger.yaml
Let’s check the status of the workflow: 
fctl orchestration workflows run <workflow-id>
We can now check the status of the workflow instance: 
fctl orchestration workflows instances show <workflow-instance-id>
