Is Lido safe to stake?

Could you please enlighten me on the safety aspect of staking with Lido? I've been hearing a lot about it, but I'm still skeptical about whether it's truly secure. Could you outline the potential risks involved and also discuss any safety measures that Lido might have implemented to safeguard its users' funds? Additionally, are there any independent audits or testimonials from satisfied users that can vouch for its safety? I'd greatly appreciate your insights on this matter.
