Hey, congrats on finishing the MVP!
I can see that when I make an offer, it start a transaction to 0x1E773A796B5B16aFA3fd91278A9924E920f82947 contract. I wanted to look it up on Etherscan, because I'm curious how you connect ERC721 tokens and youtube videos. But it seems that the source code is no uploaded there.. For me personally, I find that it increases trust in the project, when the contract source code is visible.
