OpenTransfer

When you buy a piece of art, when do you feel you own it?

Do you feel any difference between the feeling of owning that piece and the feeling you get when you purchase NFT Art? Or no difference for you?

Most NFTs allow only wallets that are tied to that NFT to transfer the NFTs. Or only third parties approved by that wallet are allowed to transfer. This is how the "ownership" of NFTs is technically achieved.

But this NFT that we made has the concept of OpenTransfer. The concept is that OpenTransfer allows “anyone” to transfer a given NFT. Yes, anyone. This would never happen in the NFT space, but if you see the relationship between things and their owners in the real world, you will see that this is a normal thing.

Would you say that you “own” this NFT that anyone can transfer?

By the way, we have only 100 of the OpenTransfer NFTs that can be minted from Etherscan for 0.01 ETH. For those who mint, please be aware that your NFT will be a transferable token that anyone can transfer. And also, all the ETH that occurred from the minting will automatically be donated to the INTERNET ARCHIVE.

INTERNET ARCHIVE Address: 0xFA8E3920daF271daB92Be9B87d9998DDd94FEF08

And you can freely move OpenTransfer NFTs owned by other accounts. You can move anyone's NFTs at any time by specifying from whom(from) to whom(to) and which token(tokenId) to move in Etherscan and executing a “Write”.
