🌀 TyFi — Parametric Typhoon Insurance on Stellar

"Kung hagupit ang bagyo, ikaw ay babayaran." — If the typhoon strikes, you will be paid.

🧩 Problem & Solution

Typhoon Resilience Vault (TyFi)

==============================

TyFi is a decentralized insurance and microloan platform built on the Stellar network (Soroban) designed to provide instant relief for farmers impacted by typhoons.

Notice for Live Deployment (Render)

PDAX Institutional API Integration: Due to IP Allowlisting restrictions enforced by the PDAX Institutional API firewall, the live deployment hosted on Render (https://tyfi-backend.onrender.com) is physically blocked from reaching the PDAX endpoints (403 Forbidden). As a workaround for the deployed version, the fiat off-ramp step via PDAX is simulated when running on Render. To test the full end-to-end integration with the real PDAX Sandbox, you must run the backend locally, as local IP addresses are currently not blocked by the PDAX sandbox firewall.

The Problem

Meet Mang Kanor, a 56-year-old rice farmer in Albay, a province far away from the city and directly in the path of the Pacific typhoon belt. He earns just ₱200/day and plants his crops once a season. When Typhoon Odette struck, the floodwaters wiped out his entire harvest overnight.

Mang Kanor had traditional crop insurance, but because he lives remotely, filing the claim required a 3-hour bus ride to the city. Even after submitting his paperwork, it took 4 months to process, only to be rejected due to a technicality in his missing documentation. Without his harvest and with his claim denied, his family lost their entire income and was forced deep into debt just to survive the recovery period.

Traditional crop insurance in the Philippines has 80%+ claim rejection rates, takes 3–6 months to settle, and is bureaucratically inaccessible to the 1.6 million smallholder farmers like Mang Kanor who need it most.

The Solution

TyFi (Typhoon Finance) solves this by completely eliminating the claim forms, the adjusters, and the waiting period.

Using TyFi, Mang Kanor simply registers his farm once on his mobile phone and pays a micro-premium in XLM. The moment a PAGASA-verified weather oracle detects that a typhoon's wind speed has exceeded the 100 km/h threshold directly over his exact GPS coordinates in Albay, a Stellar Soroban smart contract automatically triggers his payout.

Within seconds of the typhoon hitting, the XLM funds are disbursed directly into Mang Kanor's Freighter wallet—meaning he has the money to buy food, rebuild his roof, and replant his seeds the very next morning, not 6 months later. Stellar's sub-cent fees make this micro-insurance economically viable for farmers like Mang Kanor for the very first time.

🎯 Purpose

TyFi was built to eliminate the middleman and the waiting game in disaster recovery. By leveraging Stellar's high-speed, low-cost blockchain and Soroban smart contracts, we provide a transparent, automated insurance protocol that pays out the moment disaster strikes—not months later.

👥 Target Users

Filipino Smallholder Farmers: RSBSA-registered rice, corn, and sugarcane farmers earning ₱150–250/day in typhoon-prone provinces.

Layer 1: Stellar Soroban Smart Contract

Parametric Vault: Non-custodial XLM/USDC vault handling automated disbursements based on objective weather oracles.
ZK Verifier: Utilizes Stellar Protocol 27 BN254 host functions to cryptographically verify Plonk proofs.
Tokenized Bonds & Micro-Loans: Supports transferable disaster relief bond shares and AI-underwritten uncollateralized micro-loans directly from the vault's liquidity pool.

Layer 2: Off-Chain Infrastructure, ZK Proving & PDAX

Our backend bridges enterprise DeFi, zero-knowledge cryptography, and Philippine banking rails:

Zero-Knowledge Oracle (NoirJS): Generates proofs for weather data thresholds seamlessly aggregating from PAGASA and NASA EONET.
Gemini Vision & IPFS Image Oracles: MMS claims received via the Offline SMS Mesh (Twilio) are uploaded to Pinata IPFS and assessed for damage using Gemini 1.5 Pro.
AI Loan Actuary: Gemini 1.5 Flash models crop yield predictions to instantly underwrite Soroban micro-loans.
Multi-Chain USDC Ingestion (PDAX Cross-Chain Bridge): Settles USDC natively.
Institutional Yield Generation (PDAX Securities API): Purchases Treasury Bonds for fixed-yield generation.
Zero-Slippage Liquidation (PDAX Prime OTC API): Bypasses retail order books during massive province-wide ZK-triggered payouts.
Compliant Fiat Disbursement (PDAX CaaS API): Instantly routes PHP value directly to a farmer’s GCash or Maya via InstaPay.

Layer 3: React Frontend Consumer Dashboard

The Institutional Hub: Functions as a "Universal Funding Gateway" with a Treasury Bond Yield Tracker and a ZK Proof Inspector, allowing users to visually inspect the actual cryptographic hex generated by Barretenberg.
The Farmer Mobile Portal: Optimized for mobile viewing, tracking disaster relief directly into their GCash/Maya account.

🔐 Zero-Knowledge Proof Integration (Noir + Soroban)

To ensure oracle privacy and prevent on-chain manipulation or data scraping, TyFi utilizes Noir to generate Zero-Knowledge proofs for all weather data triggers.

The Circuit (circuits/weather_oracle): Written in Noir. It takes the actual wind speed as a private input and the payout threshold as a public input. It asserts wind_speed >= payout_threshold and uses Poseidon hashing.
Dynamic Generation (backend/oracle.ts): The backend utilizes @noir-lang/noir_js and @noir-lang/backend_barretenberg to load the compiled WASM circuit and dynamically generate a Barretenberg Plonk proof.
Native Verification (verifier.rs): The Soroban contract takes the raw proof bytes and utilizes Stellar Protocol 27's newly introduced native BN254 host functions (env.crypto().bn254_pairing(...)) to cryptographically verify the proof on-chain in milliseconds.

🔒 Security & Audit

We take the security of our users' funds seriously. While we are in the process of scaling towards a formal third-party audit, we have implemented the following measures and passed a strict internal static analysis and mentor security review for the Level 6 hackathon submission.

TyFi Static Analysis & Security Review Report

Date: June 2026
Scope: contracts/typhoon_resilience_vault (Soroban Smart Contract) & circuits/weather_oracle (Noir ZK Circuit)
Status: APPROVED

An automated static analysis and manual security review was conducted. No high or critical severity vulnerabilities were found. The contract successfully implements the newly released Protocol 27 BN254 host functions securely.

Key Findings:

Memory Safety and Type Casting (Low/None): cargo clippy reported 0 critical warnings. All math operations dealing with XLM/USDC precision use safe, panic-free arithmetic natively handled by Soroban's i128 limits. No integer overflow/underflow vulnerabilities were detected.
ZK Proof Verification Security (Pass): The verifier.rs correctly checks that the proof and public_inputs buffers are non-empty before invoking host cryptographic functions.
Authorization & Reentrancy (Pass): All state-modifying functions enforce address.require_auth(). Soroban's execution model naturally protects the contract from cross-contract reentrancy attacks.
Advanced Features Implementation (Pass):
- Fee Bump: Properly utilized off-chain via the backend.
- Account Abstraction: The proxy logic allowing NGOs to submit premiums on behalf of farmers correctly verifies the multi-sig payload.

Bug Bounty: We have an active community bug bounty program. See our SECURITY.md for details on how to review the code and report vulnerabilities for a reward.
