  auto ptr1=make_nft();
  nft_ptr ptr2;


This transfers the Non-Fungible Token 0x7faa4bc09c90, representing the Cow‘s reminiscence address, from ptr1 (OpenSea, Etherscan) to ptr2 (OpenSea, Etherscan).

After the transfer, ptr1 is determined to null, and ptr2 contains the fresh object, correct tackle std::unique_ptr:

  std::cout "Moved: ptr1=" " ptr2=" MakeNoise();
  Moved: ptr1=0x0 ptr2=0x7faa4bc09c90
  auto ptr1=make_nft();


  • initializes the nft_ptr runtime
  • creates the first nft_ptr
  • transfers ownership of the newly created Cow* to the nft_ptr

First, it creates an ERC-721 dapper contract that represents every reminiscence address as a Non-Fungible Token.
