Cash waqf is a form of contemporary waqf that has great potential in the modern world. In Indonesia, despite its potential of 180 trillion per year, cash waqf collection, management, and distribution are not optimal. Nonetheless, the infrastructure sector in Indonesia confronts obstacles, particularly in terms of funding. The innovation of the CWLFRA (Cash Waqf Linked DINFRA) model is, therefore, a solution to these two issues, as the proposed model is the result of an integration between efforts to optimize cash waqf and infrastructure financing via the Infrastructure Investment Fund (DINFRA). In this CWL-FRA innovation, waqf funds will be allocated to the mauquf 'alaih from the profits of infrastructure investment funds, which will become a source of long-term usable assets. As a result, the purpose of this academic paper is to develop a model capable of bolstering the ecosystem of Islamic social financial institutions and maximizing the potential achievement of cash waqf in Indonesia as a means of implementing sustainable finance and an effective instrument in reviving national economy through infrastructure development. In addition, this study seeks to determine the viability of the potential for developing the productivity of cash waqf in an effort to increase the effectiveness of achieving cash waqf to support economic sustainability with infrastructure potential. Nine respondents representing academicians and expert practitioners from both the waqf and infrastructure sectors filled out questionnaires to collect data. According to the results of the Delphi test, all respondents believed that there was a relationship between the SWOT indicators, indicating that this model is implementable. Moreover, based on the level of agreement of respondents, this model has the potential to contribute positively to national economic recovery, become a sustainable source of social funds, optimize the potential of waqf in Indonesia, strengthen the ecosystem of waqf social finance institutions, and improve the quality of management and maintenance of Indonesia's infrastructure. These findings demonstrate that integrating financial waqf with existing public infrastructure could positively affect the sustainability of national economic development. The novel aspect of this paper is the proposed cash waqf management system, which can serve as a useful reference for policymakers and waqf institutions seeking to develop a more effective waqf concept in terms of collection, administration, and distribution. Consequently, this study aims to demonstrate the potential for cash waqf, which can be integrated with DINFRA's product through the innovation of the CWL-FRA model, to become an investment instrument and offer a diversity of options to the waqf community.
