Parametric Cover on Solana

Understand the trigger. Verify the evidence.

Clima Protect makes rainfall policy outcomes inspectable on Solana. Replay completed historical data, export a tamper-evident receipt, and distinguish deterministic math from oracle trust. Test-only prototype.

How Clima Protect works

Historical replay, inspectable data and deterministic arithmetic. Actual policy settlement is a separate owner-signed test protocol path.

01

Choose your coverage

Select a region, peril type (drought or flood), observation window, and payout amount.

02

Get a signed quote

Our oracle system calculates your premium based on historical risk data. Quote is Ed25519-signed and valid for 120 seconds.

03

Policy mints on-chain

Your premium is paid in USDC. A policy account is created on Solana with your exact trigger conditions.

04

Owner-triggered settlement

After the window ends, the owner submits a settlement transaction; authenticated observations determine the outcome.

Parametric Mechanics

Index crosses threshold.
Outcome is deterministic.

Unlike traditional insurance, Clima Protect uses objective weather data indices. Choose how rainfall is measured over your observation window:

Sum—Total accumulated rainfall over the entire window

Best for drought — did the region receive enough total rain?

Mean—Average daily rainfall across the window

Best for sustained dry/wet spells — was it consistently too dry?

Max—Single highest-rainfall day within the window

Best for flash floods — did any single day exceed safe levels?

Built for trust

Every design decision prioritizes verifiability. Every data point is traceable to its oracle source.
