NFTISMUS-N Contract
Here you can find all information about the NFTISMUS-N ERC721 Token contract.
This NFT Contract will handle all standard ERC-721 transactions. For every new NFT minted, there will be a bonus payout of 10 NFM Tokens.
This contract is deployed on Polygon at the following address:
0x699624845276283e25e68cee31aa17e1463a3e5d
This token contract includes the ERC721-Standard:
IERC721TokenReceiver
IERC721Errors
IERC721Metadata
IERC721Enumerable (changed)
IERC2981
