The Stellar Network allows payments to be made across assets through path payments. A path payment specifies a series of assets to route a payment through, from source asset (the asset debited from the payer) to destination asset (the asset credited to the payee).
A path search is specified using:
- The destination account id
- The source account id
- The asset and amount that the destination account should receive
As part of the search, horizon will load a list of assets available to the source account id and will find any payment paths from those source assets to the desired destination asset. The search’s amount parameter will be used to determine if there a given path can satisfy a payment of the desired amount.
