Parametric Flight Delay Insurance Claim Tool

WHAT IT DOES

Parametric Flight Delay Insurance Claim Tool enables policyholders to submit claims for flight delay insurance policies entirely on-chain. It reads the insurance policy contract to verify your active coverage, coverage amount, premium paid, and payout amount. The tool then checks oracle-provided flight data—including scheduled departure, actual departure, and delay duration—to determine if the delay meets the policy's parametric trigger conditions. If the delay qualifies, the tool submits a claim transaction that automatically triggers the payout to your wallet, eliminating the need for manual paperwork, phone calls, or airline verification.

This tool is designed for travelers who purchase parametric flight delay insurance, where claims are settled automatically based on objective data (flight status) rather than subjective assessment. It brings the entire claim process on-chain, making it transparent, trustless, and instant.

HOW TO USE

1. Connect your EVM wallet to the network where your insurance policy is deployed.

2. Enter the insurance policy contract address (the one that issued your policy).

3. Provide your policy ID (if the contract uses numeric IDs) or leave as 0 for single-policy contracts.

4. Enter the flight number (e.g., AA123) for the flight you are claiming.

5. Enter the scheduled departure time as a Unix timestamp (e.g., 1700000000).

6. Optionally enter the actual departure time—if omitted, the tool will attempt to read it from the oracle.

7. Click "Check Policy Status" to read your policy details, current delay status, and claim eligibility.

8. Review the policy summary, including coverage, payout amount, and whether the delay qualifies.

9. Click "Submit Claim" to submit the claim transaction. The tool will automatically call the contract's claim function with the appropriate proof.

TECHNICAL MECHANISM

The tool uses a standard ERC-20/insurance contract interface to read policy data. It calls getPolicy(holder, policyId) to retrieve coverage, premium, payout, and status flags. It then checks getDelayStatus(policyId) or a similar oracle-backed function to read the delay in minutes and whether the delay threshold has been exceeded. The claim submission attempts multiple function signatures—claim(uint256,uint256), submitClaim(uint256,string,uint256,uint256), and claimWithProof(uint256,uint256,bytes32)—to support different insurance contract implementations. The tool uses gas estimation with a 20% buffer to handle network variability and calculates actual gas cost from receipt.effectiveGasPrice. All transactions are submitted sequentially with visible progress updates via a status bar.

WHAT IT CANNOT SEE

This tool cannot verify the accuracy of flight data or oracle feeds—it relies entirely on what the oracle reports. If the oracle fails to report the delay, reports incorrect times, or is compromised, the claim may be denied. It cannot assess whether the delay is covered under policy exclusions—weather events, mechanical issues, air traffic control delays, or other exceptions may not be considered "covered" even if a delay occurred. It cannot recover premiums if the claim is denied due to oracle discrepancies or policy fine print. It cannot account for manual claim reviews or human intervention—some policies may require additional off-chain verification that this tool does not handle. The tool does not simulate or predict claim outcomes; it only submits the claim based on on-chain data available at the time.

PLEASE NOTE

EVM chains only. This tool requires an insurance contract that implements parametric claims with oracle integration. Not all flight delay insurance products are on-chain or compatible. Always verify the contract address from official policy documents—phishing contracts may exist. The tool is a facilitator; it does not guarantee claim approval or payment. Test with a small policy on testnet before relying on mainnet coverage.
