Is arbitrum chain safe?

I'm curious to know, is the Arbitrum chain considered safe for use in cryptocurrency transactions? With the increasing popularity of decentralized finance and the need for scalability, I've heard of Arbitrum as a potential solution. However, I'm hesitant to trust it fully without understanding its security measures. Can you elaborate on the safety features of the Arbitrum chain and any potential risks or vulnerabilities that users should be aware of?
