Is enj built on Ethereum?

Could you elaborate on whether ENJ, the cryptocurrency token associated with the Enjin platform, is indeed built on the Ethereum blockchain? I've heard conflicting reports, and I'm interested in understanding the specifics behind this relationship. Given the widespread adoption of Ethereum and its smart contract capabilities, it would make sense if ENJ were to leverage this infrastructure. However, a definitive answer would help clear up any confusion. Is there any technical documentation or official statement that confirms ENJ's underlying blockchain platform?
