IDropERC721

Thirdweb's 'Drop' contracts are distribution mechanisms for tokens. The DropERC721 contract is a distribution mechanism for ERC721 tokens. A minter wallet (i.e. holder of MINTER_ROLE) can (lazy)mint 'n' tokens at once by providing a single base URI for all tokens being lazy minted. The URI for each of the 'n' tokens lazy minted is the provided base URI + {tokenId} of the respective token. (e.g. "ipsf://Qmece.../1"). A minter can choose to lazy mint 'delayed-reveal' tokens. More on 'delayed-reveal' tokens in this article. A contract admin (i.e. holder of DEFAULT_ADMIN_ROLE) can create claim conditions with non-overlapping time windows, and accounts can claim the tokens according to restrictions defined in the claim condition that is active at the time of the transaction.

Methods

approve

function approve(address to, uint256 tokenId) external nonpayable

Gives permission to to to transfer tokenId token to another account. The approval is cleared when the token is transferred. Only a single account can be approved at a time, so approving the zero address clears previous approvals. Requirements: - The caller must own the token or be an approved operator. - tokenId must exist. Emits an {Approval} event.

Parameters

Name	Type	Description
to	address	undefined
tokenId	uint256	undefined

balanceOf

function balanceOf(address owner) external view returns (uint256 balance)

Returns the number of tokens in owner's account.

Parameters

Name	Type	Description
owner	address	undefined

Returns

Name	Type	Description
balance	uint256	undefined

claim

getApproved

function getApproved(uint256 tokenId) external view returns (address operator)

Returns the account approved for tokenId token. Requirements: - tokenId must exist.

Parameters

Name	Type	Description
tokenId	uint256	undefined

Returns

Name	Type	Description
operator	address	undefined

isApprovedForAll

function isApprovedForAll(address owner, address operator) external view returns (bool)

Returns if the operator is allowed to manage all of the assets of owner. See {setApprovalForAll}

Parameters

Name	Type	Description
owner	address	undefined
operator	address	undefined

Returns

Name	Type	Description
_0	bool	undefined

lazyMint

function lazyMint(uint256 amount, string baseURIForTokens, bytes encryptedBaseURI) external nonpayable

Lets an account with MINTER_ROLE lazy mint 'n' NFTs. The URIs for each token is the provided _baseURIForTokens + {tokenId}.

Parameters

Name	Type	Description
amount	uint256	The amount of NFTs to lazy mint.
baseURIForTokens	string	The URI for the NFTs to lazy mint. If lazy minting 'delayed-reveal' NFTs, the is a URI for NFTs in the un-revealed state.
encryptedBaseURI	bytes	If lazy minting 'delayed-reveal' NFTs, this is the result of encrypting the URI of the NFTs in the revealed state.

ownerOf

function ownerOf(uint256 tokenId) external view returns (address owner)

Returns the owner of the tokenId token. Requirements: - tokenId must exist.

Parameters

Name	Type	Description
tokenId	uint256	undefined

Returns

Name	Type	Description
owner	address	undefined

safeTransferFrom

function safeTransferFrom(address from, address to, uint256 tokenId) external nonpayable

Safely transfers tokenId token from from to to, checking first that contract recipients are aware of the ERC721 protocol to prevent tokens from being forever locked. Requirements: - from cannot be the zero address. - to cannot be the zero address. - tokenId token must exist and be owned by from. - If the caller is not from, it must have been allowed to move this token by either {approve} or {setApprovalForAll}. - If to refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer. Emits a {Transfer} event.

Parameters

Name	Type	Description
from	address	undefined
to	address	undefined
tokenId	uint256	undefined

safeTransferFrom

function safeTransferFrom(address from, address to, uint256 tokenId, bytes data) external nonpayable

Safely transfers tokenId token from from to to. Requirements: - from cannot be the zero address. - to cannot be the zero address. - tokenId token must exist and be owned by from. - If the caller is not from, it must be approved to move this token by either {approve} or {setApprovalForAll}. - If to refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer. Emits a {Transfer} event.

Parameters

setApprovalForAll

function setApprovalForAll(address operator, bool _approved) external nonpayable

Approve or remove operator as an operator for the caller. Operators can call {transferFrom} or {safeTransferFrom} for any token owned by the caller. Requirements: - The operator cannot be the caller. Emits an {ApprovalForAll} event.
