Variants

Transfer

@dev This emits when ownership of any NFT changes by any mechanism. This event emits when NFTs are created (from == 0) and destroyed (to == 0). Exception: during contract creation, any number of NFTs may be created and assigned without emitting Transfer. At the time of any transfer, the approved address for that NFT (if any) is reset to none.

Fields

from: Address

to: Address

token_id: U256

Approval

@dev This emits when the approved address for an NFT is changed or reaffirmed. The zero address indicates there is no approved address. When a Transfer event emits, this also indicates that the approved address for that NFT (if any) is reset to none.

Fields

owner: Address

approved: Address

token_id: U256

ApprovalForAll

@dev This emits when an operator is enabled or disabled for an owner. The operator can manage all NFTs of the owner.

Fields

owner: Address

operator: Address

approved: bool
