# Why Buy a Cover
In the world of DeFi, risks such as protocol hacks, wallet breaks, and stablecoin depegging are on the rise. While the potential for high returns is thrilling, losing your assets due to unforeseen events can be devastating.
**Buying a cover (insurance)** is a smart way to protect your investments and gain peace of mind. It ensures that even if something goes wrong, you have a safety net to recover your losses. Think of it as a shield for your crypto assets, enabling you to confidently explore DeFi opportunities without constantly worrying about risks.
With an increase of **30% hacks on DeFi platforms in 2024**, having insurance is more important than ever. Secure your assets today and invest with confidence. Bright Union allows searching the DeFi positions by the wallet address, and finds the best coverage possible.
### Algorithm for searching
| Step | Comment |
| ------------------------------------ | ----------------------------------------------------------------------------------------------------------------- |
| DeFi positions by the wallet address | The search is performed cross multiple EVM chains, such as Ethereum, Base, Optimism, Arbitrum, etc |
| Highest exposure, USD denominated | There is one 'Cover amount' for the whole portfolio, we look for the highest exposure the wallet has, in USD |
| Best product on the market | We look cross chains, cross risk providers to find the best coverage product that would cover the whole portfolio |
| Optional: Add an extra protocol | The user can add an extra protocol to be included into the coverage |
