Wrapped ITEMs from ERC1155

To wrap a single or multiple object of an ERC1155 token at the same time, you need to use the safeTransferFrom(address from, address to, uint256 tokenId, uint256 tokenAmount, bytes calldata data) and safeBatchTransferFrom(address from, address to, uint256[] calldata tokenIds, uint256[] calldata tokenAmounts, bytes calldata data) external standard functions, indicating the address of the Orchestrator as a token receiver.

For every unique objectId, a new ITEM will be created to wrap it, minting the cumulative amount passed in the call.

On the first wrapping, a collection is created by the Orchestrator. This collection implements the “function onERC1155Received(address operator, address from, uint256 tokenId, uint256 tokenAmount, bytes calldata data) external returns (bytes4);” and function onERC1155BatchReceived(address operator, address from, uint256[] calldata tokenIds, uint256[] calldata tokenAmounts, bytes calldata data) external returns (bytes4);” standard functions to receive other NFTs of the collection it wraps. This means that to wrap new items, you can save gas bypassing the Orchestrator and directly send the NFTs to the collection using the function safeTransferFrom(address from, address to, uint256 tokenId, uint256 tokenAmount, bytes calldata data) external; and safeBatchTransferFrom(address from, address to, uint256[] calldata tokenIds, uint256[] calldata tokenAmounts, bytes calldata data) ERC1155 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.

If the wrapped object supports decimals greater than 1, both the Collection (ERC1155) and the ERC20 versions of the ITEMs will share the same number of decimals as the original object.

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.
