Is WIF on ETH?

Could you please clarify for me if WIF exists on the Ethereum blockchain? I've heard rumors about it being integrated, but I'm not entirely sure. Could you provide any insights or evidence to support or refute this claim? I'm particularly interested in understanding the technical details and how it might impact the Ethereum ecosystem if it is indeed present. Additionally, are there any security considerations or potential risks associated with WIF on ETH that I should be aware of? Thank you for your assistance in clarifying this matter.
