What network do I need to send AVAX?

Could you please clarify which network I should use to send AVAX tokens? I'm new to this and want to ensure I'm using the right platform to transfer my assets securely. I've heard of different networks like Ethereum, Binance Smart Chain, and of course, Avalanche's own network. Is there a specific network that AVAX is native to, or can I use any of these options? Additionally, are there any fees or considerations I should be aware of when choosing a network for sending AVAX? Your guidance would be greatly appreciated.
