Levee watches landslide risk in real time. The instant an on-chain threshold breaks, USDC streams straight to affected community wallets — no committee, no delay, fully auditable.
The problem. Heavy rain on fragile slopes — like the 1998 Sarno (Campania) debris flows — destroys homes and critical infrastructure in minutes. Relief arrives in weeks, through opaque channels. Risk models exist, but the path from a forecast to money on the ground is slow and untrusted.
Four stages, each independently verifiable.
Calibrated LightGBM turns rainfall, soil saturation and terrain into a landslide probability with explainable factors.
A Switchboard On-Demand feed carries the probability on-chain, with staleness and sample guards.
An immutable, on-chain threshold — not an LLM — authorizes relief. Cap & cooldown enforced; every decision logged.
Pays USDC only to registered community wallets, with human-in-the-loop for large amounts. Fails closed on stale data.
Maps risk onto National-Transmission-Grid assets (towers, substations, lines) and raises WATCH / WARNING / CRITICAL alerts before damage.
The payout rule is on-chain and public. Anyone can re-compute it. No discretionary human in the money path, no black-box model deciding funds.
When the on-chain threshold is crossed, pre-funded USDC reaches affected communities in one transaction — no claims, no committees.
Autonomous, bounded, transparent relief — built for the next decade of AI × Web3.
