Abstract

SHELTR represents a revolutionary enterprise-grade platform that addresses homelessness through traditional payment stability combined with blockchain transparency. By integrating payment processing,Coinbase institutional staking, and single-token housing fund tracking, SHELTR creates a zero-risk bridge between donors and individuals experiencing homelessness while building sustainable long-term solutions.

Our single-token stable architecture uses the SHELTR Stablecoin (USDT-pegged) exclusively for housing fund tracking and transparency, while participants receive virtual debit cards with 80% of donations, eliminating cryptocurrency volatility exposure. This innovative approach ensures 100% of donations reach their intended purposes: 80% participant support via traditional payment cards, 15% housing fund growth through guaranteed 4-6% APY institutional staking, and 5% shelter operations support—all verified on-chain for complete transparency with zero participant risk.

Our platform launches with enterprise partnerships providing institutional-grade infrastructure,traditional funding models eliminating ICO speculation, and guaranteed returns through Coinbase Prime institutional custody and staking services.

Enterprise Payment Architecture

SHELTR's infrastructure is built on proven enterprise partnerships with payment processing for global credit card acceptance and virtual card issuance, and Coinbase Prime for institutional-grade custody and staking. Our smart contract architecture on Base network implements OpenZeppelin security standards with multi-signature governance and emergency pause capabilities.

The platform integrates Firebase Firestore for real-time multi-tenant data management, FastAPI for high-performance backend services, and Next.js 15 for enterprise-grade frontend experiences. All participant funds are processed through traditional payment infrastructure with zero cryptocurrency exposure.
