Decentralized Finance and Sharia Economic Law

Abstract

The rapid expansion of Decentralized Finance (DeFi), powered by blockchain technology, has transformed global financial systems by offering peer-to-peer, intermediary-free services. However, its compatibility with Islamic economic law (hukum ekonomi syariah) remains uncertain due to potential violations of Sharia principles such as the prohibition of riba (usury), gharar (excessive uncertainty), and maysir (speculation). This study addresses this gap by employing a qualitative maqāṣid al-sharī‘ah-based analysis to assess the alignment of DeFi mechanisms decentralized exchanges, lending protocols, and smart contracts with Islamic ethical and legal values. Data were collected through literature review and document analysis from classical Islamic sources, fatwas, and current DeFi documentation. The findings show that while many DeFi practices contain non-compliant elements, their underlying technology particularly smart contracts and decentralized governance holds significant potential for adaptation. When structured using Sharia-compliant contracts such as murābaḥah, mushārakah, or wakālah, and guided by maqāṣid objectives like ḥifẓ al-māl (preservation of wealth) and ḥifẓ al-dīn (preservation of faith), DeFi can support financial inclusion, transparency, and justice in accordance with Islamic law. This study proposes a normative framework for building Sharia-compliant DeFi platforms, integrating technical innovations with ethical governance, thereby offering a transformative model for Islamic finance in the digital era.
