Payments for the paid usage of Filecoin Onchain Cloud are currently being processed through Filecoin Pay. Looking forward, the next planned item on the roadmap is the introduction of sponsored payment rails. This upcoming functionality will give applications the ability to cover storage fees on behalf of their audience. As a result, individuals will be able to seamlessly use an app without the need to purchase their own storage space.
