Opensea has the deals feature for trading, but there’s limitations. Don’t think you can bundle verified NFTs with non verified, and some other things

Our standard @rmrk allows this too with Nestable ERC. You transfer NFTs to other NFTs, then you can just sell the parent, and all the children will go with it. It's somewhat similar to TBA, but TBA is NFT -> AA -> NFT. Where as RMRK is NFT -> NFT. Another big difference is TBA works with any existing contract, but RMRK has to use our ERC from the start, although offers some more functionality as part of the contract
