Integration with a marketplace

[quantix-nft]

hello, I'm developing a new nft marketplace where users can sell and buy NFT.
In the current version, my smartcontract transfers NFT from buyer to seller and erc20 tokens from seller to buyer. No auctions, just a buy now, so after click the exchange is done. Everything works fine, but I dont understand if I need mandatory to use wyvern (and how) in order for my trade to be listed on opensea in example or on nft-stats.com.
Thank you
