Enabling organizations to reimburse real-world expenses for employees, students, and hackers.
Problem Statement
Organizations can register reimbursements for specific real-world expenses — such as taking an Uber ride to a designated destination, making a booking, or completing a purchase. They can also define additional requirements, such as owning an NFT or not being from a country on the OFAC sanctions list. Once users verify they meet the criteria, reimbursements are automatically issued.
Solution
Our project is built with Next.js.When an organization submits a reimbursement, they define the metadata and requirements users must meet to claim it. To confirm the submission, the organization signs a message with their wallet. After that, they approve USDC to fund the reimbursement.Users who want to claim a reimbursement must verify that all requirements are met:On-chain events — like holding a specific NFT — are verified via an RPC call using the user’s wallet. Identity-based criteria — such as not being from a country on the OFAC sanctions list — are verified using the Self protocol. Off-chain actions — such as taking an Uber ride to a specific location — are validated using confirmation emails and their DKIM signatures.Once all conditions are verified, rewards are automatically distributed via USDC transfers.
