Levee

Autonomous Parametric Relief Agent for Hydrogeological Risk on Solana

1. Project Detailed Overview

When hydrogeological disasters strike, the most critical factor is the speed of financial aid. Traditional relief systems and insurance processes are notoriously slow, requiring weeks or months of damage assessment, bureaucratic approvals, and paperwork. This leaves affected families without the immediate liquidity needed for urgent necessities, temporary housing, and food.

Levee redefines disaster relief by introducing a parametric model powered by AI and Web3. Instead of evaluating damage post-facto (which is subjective and slow), Levee monitors objective physical triggers in real time.

The system leverages:

1. AI-driven Risk Fusion: An AI model + LLM Agents that continuously ingests meteorological data (intensity/duration of rainfall), static soil susceptibility layers (slope, geology, land use), and soil moisture levels to predict landslide risks.
2. On-Chain Oracles: Switchboard On-Demand feeds that push verified climate data and risk scores to the Solana blockchain securely via Trusted Execution Environments (TEEs).
3. Autonomous Execution: A dedicated AI agent that monitors risks, interacts with blockchain programs, and automatically triggers payouts to affected communities within minutes of a threshold breach.

2. Track & Bounty Integration Details

Solana: Solana provides the high-performance, low-latency, and low-cost infrastructure necessary to orchestrate real-time, autonomous agent activities and micro-transactions.

• Why Solana? Instant settlement and sub-penny fees allow the agent to distribute micro-payments directly to thousands of individual wallets simultaneously without eating into the relief fund.
• Autonomous On-Chain Actor: Built using the Solana Agent Kit (SendAI), Levee is a first-class citizen on the blockchain. It holds its own cryptographic wallet, manages the liquidity vault, performs real-time risk evaluations off-chain, and programmatically signs and submits settlement transactions.
• Anchor Framework: The core logic governing pre-registered thresholds, beneficiary registries, cooldown periods, and anti-fraud mechanisms is written securely in Rust using the Solana Anchor framework.

0xbow Privacy Pools:

• What to build: Build a UI on top of privacy pools v2 (e.g., payroll, swaps/OTC, tx splitter, etc.).
• The Privacy Challenge: In a public blockchain ledger like Solana, distributing relief funds directly to individual wallets exposes the transaction history and balances of vulnerable disaster victims. This violates their financial privacy and can expose them to security threats or predatory targeting.
• The Levee Solution: Levee integrates Privacy Pools v2 as an autonomous, private transaction splitter/payroll protocol.
• How it works: The AI agent manages a master USDC relief vault. When a disaster is triggered, instead of making public transfers, the agent deposits the funds into Privacy Pools v2. It then executes a private payroll/splitter routine, distributing shielded USDC to the registered wallets of affected citizens.
• Compliance & Transparency: By leveraging zero-knowledge proofs (ZKPs), victims can withdraw their relief funds privately, proving their transaction originates from a legitimate disaster pool, while maintaining full public auditability of the aggregate relief funds distributed.

Blockchain for Good Alliance (BGA): The Blockchain for Good Alliance brings together projects leveraging blockchain to drive real-world, positive change. Levee natively aligns with BGA's core values:

• Social and Environmental Impact: Directly supports and cushions vulnerable communities against climate-induced hydrogeological disasters (landslides, mudslides) through immediate financial aid.
• Transparency and Accountability: Prevents administrative corruption and friction. Every pre-registered threshold, AI decision log, and transaction payload is immutably documented on-chain, proving exactly how and where relief funds were deployed.
• Open Collaboration and Interoperability: Built on open-source frameworks (Solana Agent Kit, Switchboard Oracles, Privacy Pools v2), allowing researchers and developers to adapt the code for other regions or risks.
• Scalable and Sustainable Solutions: The parametric model can scale globally to address other climate risks (e.g., floods, droughts, wildfires) at near-zero administrative costs.
