# Execute Smart Transfers

# Create a Smart Transfer ticket

1. Call this [endpoint](/reference/createticket) to create a Smart Transfer ticket.
2. In the **NetworkId** field, enter the Network profile of the counterparties you want to create a smart transfer with.
3. Under the **terms** field, add assets and amounts that are going to be exchanged.

In the example below, we are exchanging 1.23 BTC for 23.213 ETH, where:

1. BTC will be sent from Network ID `e41bd5cb-088c-41f2-bb6c-9fb027075e5a` to

   Network ID `798ac350-8aec-459f-96f5-505481933f98`.

2. ETH will be sent from Network ID `798ac350-8aec-459f-96f5-505481933f98` to

   Network ID `e41bd5cb-088c-41f2-bb6c-9fb027075e5a`.

# Fund Smart Transfer ticket

To fund the Smart Transfer ticket call this [endpoint](/reference/fulfillticket). You can fund a ticket in any order, i.e. any side can go first. In order to fund a ticket, you must first define the funding source (vault or connected exchange account).

***

# Cancel Smart Transfer ticket

To cancel a ticket, call this [endpoint](/reference/cancelticket). Canceling is only possible if none of the ticket’s legs (terms) have been previously funded. Otherwise, only the side that already funded the ticket has the ability to cancel it.
