Is FTM built on ETH?

Could you please clarify for me whether FTM is indeed constructed on the ETH blockchain? I'm interested in understanding the technological foundation of FTM and its relationship, if any, with Ethereum. Could you elaborate on the specifics of this relationship, if it exists? Is FTM leveraging the capabilities of the ETH network in some way? Or is it an entirely separate and independent project? I'm keen to know the details behind this question, as it seems to be a crucial aspect in understanding the nature and function of FTM. Thank you for your time and assistance in clarifying this matter for me.
