As high return in DeFi attracting extensive teams building up thousands of DeFi protocols, only very few of them are launched with prudent pre-launch audit and examination, which leaves the main risk of assets security to the mass users of those protocols. Facing the threats of such hacks and exploits, De-Fi users are naturally looking to turn to insurance products, searching for protections of their assets. However, we have not seen efficient insurance coverage appeared in the traditional insurance market. As the history of De-Fi is very recent, the data available for actuarial analysis is limited, which is the main reason why such coverages are not offered by traditional insurance companies. With the rapid expansion of De-Fi products, it is foreseen the protection gaps of these newer risks will remain unfilled for a long time.
