Multi-Chain Insurance Coverage Aggregator

WHAT IT DOES

This tool connects to your EVM wallet and scans multiple decentralized insurance protocols—including Nexus Mutual, InsurAce, Etherisc, and compatible forks—across different EVM chains. It reads your policy holdings and coverage positions, displaying key details such as coverage amounts, premiums paid, expiry blocks, and active status. The tool aggregates all policies into a single dashboard, showing total coverage across all protocols and chains, with a breakdown of each individual policy.

HOW TO USE

Connect your Web3 wallet using the Connect button. The tool will automatically detect your connected wallet address and pre-fill the address field, but you can also enter any address to monitor. In the Protocol Configurations textarea, enter each insurance protocol you want to scan in the format name:contract:chain—one per line. For example, "NexusMutual:0x4b8a4D1F6a2Ff6b9A6B0F4A9A8F0A9A8F0A9A8F0:1" for Nexus Mutual on Ethereum mainnet or "InsurAce:0x...:137" for InsurAce on Polygon. Click "Scan Policies" to fetch all coverage positions. Results appear in the Results card with a summary of total policies, active policies, total coverage, and a detailed list of each policy with its status and details.

TECHNICAL MECHANISM: MULTI-INTERFACE POLICY DETECTION

The tool uses ethers.js to interact with insurance protocol contracts through a tiered ABI detection system. First, it attempts getPolicy(address), the standard interface used by Nexus Mutual and many forks, which returns coverage amount, premium, expiry block, and active status in a single call. If that fails, it falls back to policies(address) used by other protocols. As a third fallback, it tries coverageOf(address) for simpler implementations that only return coverage amount. Each policy is parsed from raw BigNumber values and normalized to human-readable format. The tool aggregates total coverage by summing active policies, using ethers.BigNumber to maintain precision. All data is fetched on-demand through the connected provider, with proper error handling for each protocol query.

WHAT IT CANNOT SEE

This tool cannot verify off-chain claims processing or actual claim payouts—it only reads on-chain policy data. It cannot assess the solvency, risk assessment methodologies, or financial health of insurance protocols. It cannot detect policies that do not use standard on-chain tracking interfaces or custom implementations. The tool relies on protocol-specific ABIs and may not support all insurance providers—if a protocol uses a non-standard interface, policies may not be detected. It cannot predict future claim events, policy performance, or changes in coverage terms. Off-chain policy details or documentation are not accessible through this tool.

PLEASE NOTE

This is a read-only tool—it never signs transactions or requests write permissions. All data is fetched on-demand and stored only in memory; nothing is persisted across page reloads. The tool supports EVM chains only—Ethereum, Polygon, BSC, Arbitrum, Optimism, Avalanche, Base, and Fantom. Always verify that the contract addresses you enter are correct and correspond to the insurance protocols you intend to query. The example addresses shown are placeholders—replace them with actual contract addresses from the respective protocols.
