About

The problem it solves QRBN.app solves the biggest pain in Islamic giving today, you never really know where your donation goes. In Islam, Zakat is a required annual charity (usually 2.5% of one’s wealth) given to the poor, while Qurban is the ritual animal sacrifice performed during Eid al-Adha, often split among families and the needy. We use DeFi principles like smart contracts, DAOs, and on-chain transparency. Not for lending or yield farming, but to give Muslims a way to verify, trace, and govern their Zakat and Qurban. No more blind trust. Now your faith, your impact, and your voice are all verifiable. **Zakat and Qurban problem** • Verifiable proof their Qurban was properly executed • Transparency on how Zakat funds are used • Any say in where their money goes or who benefits **QRBN.app solution** - Qurban-as-a-Service: Join a 1/7th cow pool via smart contract - Zakat Tools: Auto-calculation + NGO routing + public dashboard - NFT Certificates: Get GPS-verified proof of sacrifice - DAO Voting: Propose or vote on campaigns and vendors - Multisig Treasury: Secured by Shariah, Community, Org, Founder roles - Media Upload System: timestamped slaughter videos and recipient proof We make Islamic giving verifiable, participatory, and transparent.

How it's made

Challenges we ran into One hurdle we faced was integrating our video demo inside Devfolio, the platform currently doesn't support inline video playback, so we had to link externally in google drive on project links instead of embedding the experience we built. Another challenge was designing a DAO structure that respects both the principles of decentralization and the authority of Shariah governance. We iterated several times before landing on a role-based DAO with weighted votes and fatwa veto rights, allowing both community voice and religious compliance to coexist transparently. Overall, development went smoothly, and this architecture became one of our strongest innovations.
