Pair Contract wallet, public one and private one. Only public one can send NFTs to private one.
We avoid scam NFTs. Evil people can send it to someone permissionless. We think it is a problem.
We make pair contract wallet using erc4337. There is public and private one. Everyone can send spam NFT to public one. But Nobody can send it to private one. (It haven't developed)
You can arrange NFTs between them. So you can flex and show your favorite NFTs clearly.
