Wrapped ITEMs from ERC721
To wrap an ERC721, you need to use the safeTransferFrom(address from, address to, uint256 tokenId, bytes calldata data) external standard function, indicating the address of the Orchestrator as a token receiver.
One ITEM for each token. On the first wrapping, a collection is created by the Orchestrator. This collection implements the “function onERC721Received(address operator, address from, uint256 tokenId, bytes calldata data) external returns (bytes4);” standard function to receive other NFTs of the collection it wraps. This means that to wrap new ITEMs, you can save gas by bypassing the Orchestrator and sending the NFTs directly to the collection using the function safeTransferFrom(address from, address to, uint256 tokenId, bytes calldata data) external; ERC721 standard method.
For each newly-wrapped NFT, a single ITEM will be added to the Collection and a new ERC20 will be minted, but the ERC20 objectId will always be the same.
The generated ITEM will have decimals equal to 1 when viewed as a part of a Collection and 18 decimals when viewed as an ERC20.
