How to send ETH to Mantle network?

Could you please explain to me how exactly I can send Ethereum (ETH) to the Mantle network? I'm not very familiar with this process and would appreciate step-by-step instructions. Do I need to use a specific wallet or platform for this transfer? Are there any fees involved, and if so, how are they calculated? Also, is there a way to ensure the security of my transaction and prevent any potential risks? Thank you for your assistance in this matter.
