Is TRX built on Ethereum?

Could you please clarify, is TRX actually constructed on the Ethereum blockchain? I've heard some rumors about this, but I'm not entirely sure. It would be greatly appreciated if you could provide some insights into this matter. Is TRX compatible with Ethereum's smart contracts, or does it operate independently? Also, does TRX leverage any of Ethereum's security features or consensus mechanisms? I'm quite curious to understand the technical aspects behind this. Thank you in advance for your clarification.
