TownPlanPay solves the $1.2T infrastructure payment crisis by automating USDC disbursements when AI verifies real-world project milestones. THE PROBLEM: Municipal contractors in emerging markets wait 6-12 months for payments, stalling roads, schools, and water projects. This $1.2T annual problem delays critical infrastructure worldwide. OUR SOLUTION: • AI Verification: Cloudflare Workers analyze contractor evidence (photos, GPS, documents) • Instant Payments: Circle API triggers USDC disbursements when milestones are verified • Transparent Recording: Arc Testnet records every transaction permanently • 360 Days → 5 Minutes: Complete payment process acceleration TECHNICAL STACK: • AI: Cloudflare Workers with custom verification logic • Payments: Circle USDC API + Developer-Controlled Wallets • Blockchain: Arc Testnet for EVM-compatible settlements • Backend: Python/Flask with Node.js integration • Frontend: React with real-time status updates DEMONSTRATION: Our working MVP runs locally with complete end-to-end flow: 1. Contractor submits evidence through portal 2. Cloudflare AI verifies milestone completion 3. Circle API processes USDC payment 4. Arc Testnet records immutable transaction 5. Full audit trail from evidence to payment IMPACT & SCALING: Starting with Nigeria's $100B infrastructure market, we're building transparent, instant payment infrastructure for global municipal projects. Every transaction eliminates corruption risk and accelerates community development.

PayGuard is a decentralized application that tackles the critical issue of delayed wages for gig economy workers and private security personnel. It transforms a situation of helplessness into one of verifiable leverage by automatically generating tamper-proof, on-chain evidence the moment a salary is overdue. How it Works: When a payment is delayed, PayGuard immutably records the debt obligation on the Solana blockchain, mints a "Proof of Debt" NFT via Crossmint as undeniable evidence, and autonomously generates and sends professional communications to the employer via Mistral AI and ElevenLabs. The Key Differentiator: Unlike other solutions, PayGuard's integration with the Anchor (Coral v1) framework provides a censorship-resistant, decentralized backbone. This ensures the system remains fully operational even if traditional APIs are restricted, making PayGuard a truly unstoppable protocol for worker's rights.

AuditChain Qubic Track AuditChain is a decentralized smart contract auditing tool built for the Qubic Track at RAISE Your Hack 2025. It helps developers detect vulnerabilities like reentrancy attacks, overflows, and logic flaws before deploying their contracts. Developers can upload or paste their smart contract code into the tool, which then performs a static analysis to identify known risks. The result is a structured audit report, and its hash is committed to the Qubic testnet as immutable proof of audit, ensuring transparency and trust. AuditChain promotes verifiable security in smart contract development using Qubic’s decentralized compute environment. The project also sets the foundation for future integrations like dynamic analysis, Slither/MythX support, and an on-chain audit explorer.
