ERC-721 Validator

This is a validator that checks if a smart contract fully follows the ERC721 standard.
Validator is divided in 3 steps depending on the information and actions needed:

• For Basic validation you only need the contract address.
• For Token validation you also need a valid ID of any NFT.
• For Transfer validation you need to approve a token NFT

Example smart contracts you can test:

• CryptoKitties: 0x06012c8cf97BEaD5deAe237070F9587f8E7A266d
• 0xcert ERC-721 implementation: 0xf176d7bcdD07f8e474877095870685Ef0CCcCb2D
  Token ID: 1, Approved token ID: 1
• Decentraland: 0xf87e31492faf9a91b02ee0deaad50d51d56d5d4d
