The Universal Nexus Finance for Sustainable Development (UNFSD) is GRA’s sovereign-grade, smart contract–driven co-financing mechanism that ties capital deployment directly to clause-verified corridor performance. By linking milestone-based funding to real-time corridor observability and fallback scenario compliance, UNFSD ensures that resilience corridors, Nexus modules, and innovation programs are transparently funded, auditable, and aligned with national and international risk governance standards. It provides member institutions with a secure, automated financial backbone to scale trusted, sustainable development infrastructure where needed most.
