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

• INFMController

• INFMMint
