Be wary of crypto/blockchain bridges!

[The Cryptovator]

I assume the bridge operates on the smart contract. Hackers are able to drain funds when there is a bug in the smart contract which is quite dangerous. I don't know how this happens where a lot of Audit companies like Certik exist. How do bugs exist on the smart contract? Anyway, I had never used a bridge. Rather than I will use cex or sell directly to the dex. I don't want to risk the funds.
