It enables insurers/underwriters to launch insurance policies on-chain, protecting policyholders from risk and providing profit potential for liquidity providers. Protocol participants include: * Pool manager - underwrite policy, modify policy parameters, and submit claim * Liquidity provider - As a liquidity provider, you can deposit collateral and earn a yield. * Policyholders - Purchase insurance policies and pay premiums. * Committees - vote on a claim, and propose and vote on a manager or committee member change.
