= ERC 721

[.readme-notice]
NOTE: This document is better viewed at https://docs.openzeppelin.com/contracts/api/token/erc721

This set of interfaces, contracts, and utilities are all related to the https://eips.ethereum.org/EIPS/eip-721[ERC721 Non-Fungible Token Standard].

TIP: For a walk through on how to create an ERC721 token read our xref:ROOT:erc721.adoc[ERC721 guide].

The EIP specifies four interfaces:

* {IERC721}: Core functionality required in all compliant implementation.
* {IERC721Metadata}: Optional extension that adds name, symbol, and token URI, almost always included.
* {IERC721Enumerable}: Optional extension that allows enumerating the tokens on chain, often not included since it requires large gas overhead.
* {IERC721Receiver}: An interface that must be implemented by contracts if they want to accept tokens through `safeTransferFrom`.

OpenZeppelin Contracts provides implementations of all four interfaces:

* {ERC721}: The core and metadata extensions, with a base URI mechanism.
* {ERC721Enumerable}: The enumerable extension.
* {ERC721Holder}: A bare bones implementation of the receiver interface.

Additionally there are a few of other extensions:

* {ERC721Consecutive}: An implementation of https://eips.ethereum.org/EIPS/eip-2309[ERC2309] for minting batchs of tokens during construction, in accordance with ERC721.
* {ERC721URIStorage}: A more flexible but more expensive way of storing metadata.
* {ERC721Votes}: Support for voting and vote delegation.
* {ERC721Royalty}: A way to signal royalty information following ERC2981.
* {ERC721Pausable}: A primitive to pause contract operation.
* {ERC721Burnable}: A way for token holders to burn their own tokens.

NOTE: This core set of contracts is designed to be unopinionated, allowing developers to access the internal functions in ERC721 (such as <<ERC721-_mint-address-uint256-,`_mint`>>) and expose them as external functions in the way they prefer. On the other hand, xref:ROOT:erc721.adoc#Presets[ERC721 Presets] (such as {ERC721PresetMinterPauserAutoId}) are designed using opinionated patterns to provide developers with ready to use, deployable contracts.

[.contract-item]
[[IERC721-balanceOf-address-]]
==== `[.contract-item-name]#++balanceOf++#++(address owner) → uint256 balance++` [.item-kind]#external#

Returns the number of tokens in ``owner``'s account.

[.contract-item]
[[IERC721-ownerOf-uint256-]]
==== `[.contract-item-name]#++ownerOf++#++(uint256 tokenId) → address owner++` [.item-kind]#external#

Returns the owner of the `tokenId` token.

Requirements:

- `tokenId` must exist.

[.contract-item]
[[IERC721-safeTransferFrom-address-address-uint256-bytes-]]
==== `[.contract-item-name]#++safeTransferFrom++#++(address from, address to, uint256 tokenId, bytes data)++` [.item-kind]#external#

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.

[.contract-item]
[[IERC721-safeTransferFrom-address-address-uint256-]]
==== `[.contract-item-name]#++safeTransferFrom++#++(address from, address to, uint256 tokenId)++` [.item-kind]#external#

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.

[.contract-item]
[[IERC721-transferFrom-address-address-uint256-]]
==== `[.contract-item-name]#++transferFrom++#++(address from, address to, uint256 tokenId)++` [.item-kind]#external#

Transfers `tokenId` token from `from` to `to`.

WARNING: Note that the caller is responsible to confirm that the recipient is capable of receiving ERC721
or else they may be permanently lost. Usage of {safeTransferFrom} prevents loss, though the caller must
understand this adds an external call which potentially creates a reentrancy vulnerability.

Requirements:

- `from` cannot be the zero address.
- `to` cannot be the zero address.
- `tokenId` token must be owned by `from`.
- If the caller is not `from`, it must be approved to move this token by either {approve} or {setApprovalForAll}.

Emits a {Transfer} event.

==== `[.contract-item-name]#++approve++#++(address to, uint256 tokenId)++` [.item-kind]#external#

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.

[.contract-item]
[[IERC721-setApprovalForAll-address-bool-]]
==== `[.contract-item-name]#++setApprovalForAll++#++(address operator, bool _approved)++` [.item-kind]#external#

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.

[.contract-item]
[[IERC721-getApproved-uint256-]]
==== `[.contract-item-name]#++getApproved++#++(uint256 tokenId) → address operator++` [.item-kind]#external#

Returns the account approved for `tokenId` token.

Requirements:

- `tokenId` must exist.

[.contract-item]
[[IERC721-isApprovedForAll-address-address-]]
==== `[.contract-item-name]#++isApprovedForAll++#++(address owner, address operator) → bool++` [.item-kind]#external#

Returns if the `operator` is allowed to manage all of the assets of `owner`.

See {setApprovalForAll}

[.contract-item]
[[IERC721-Transfer-address-address-uint256-]]
==== `[.contract-item-name]#++Transfer++#++(address indexed from, address indexed to, uint256 indexed tokenId)++` [.item-kind]#event#

Emitted when `tokenId` token is transferred from `from` to `to`.

[.contract-item]
[[IERC721-Approval-address-address-uint256-]]
==== `[.contract-item-name]#++Approval++#++(address indexed owner, address indexed approved, uint256 indexed tokenId)++` [.item-kind]#event#

[.contract-item]
[[IERC721-ApprovalForAll-address-address-bool-]]
==== `[.contract-item-name]#++ApprovalForAll++#++(address indexed owner, address indexed operator, bool approved)++` [.item-kind]#event#

Emitted when `owner` enables or disables (`approved`) `operator` to manage all of its assets.

==== `[.contract-item-name]#++_safeTransfer++#++(address from, address to, uint256 tokenId, bytes data)++` [.item-kind]#internal#

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.

`data` is additional data, it has no specified format and it is sent in call to `to`.

This internal function is equivalent to {safeTransferFrom}, and can be used to e.g.
implement alternative mechanisms to perform token transfer, such as signature-based.

Requirements:

- `from` cannot be the zero address.
- `to` cannot be the zero address.
- `tokenId` token must exist and be owned by `from`.
- If `to` refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer.

Emits a {Transfer} event.

[.contract-item]
[[ERC721-_ownerOf-uint256-]]
==== `[.contract-item-name]#++_ownerOf++#++(uint256 tokenId) → address++` [.item-kind]#internal#

[.contract-item]
[[ERC721-_exists-uint256-]]
==== `[.contract-item-name]#++_exists++#++(uint256 tokenId) → bool++` [.item-kind]#internal#

Returns whether `tokenId` exists.

Tokens can be managed by their owner or approved accounts via {approve} or {setApprovalForAll}.

Tokens start existing when they are minted (`_mint`),
and stop existing when they are burned (`_burn`).

[.contract-item]
[[ERC721-_isApprovedOrOwner-address-uint256-]]
==== `[.contract-item-name]#++_isApprovedOrOwner++#++(address spender, uint256 tokenId) → bool++` [.item-kind]#internal#

Returns whether `spender` is allowed to manage `tokenId`.

Requirements:

- `tokenId` must exist.

[.contract-item]
[[ERC721-_safeMint-address-uint256-]]
==== `[.contract-item-name]#++_safeMint++#++(address to, uint256 tokenId)++` [.item-kind]#internal#

Safely mints `tokenId` and transfers it to `to`.

Requirements:

- `tokenId` must not exist.
- If `to` refers to a smart contract, it must implement {IERC721Receiver-onERC721Received}, which is called upon a safe transfer.

Emits a {Transfer} event.

[.contract-item]
[[ERC721-_safeMint-address-uint256-bytes-]]
==== `[.contract-item-name]#++_safeMint++#++(address to, uint256 tokenId, bytes data)++` [.item-kind]#internal#

Same as {xref-ERC721-_safeMint-address-uint256-}[`_safeMint`], with an additional `data` parameter which is
forwarded in {IERC721Receiver-onERC721Received} to contract recipients.

[.contract-item]
[[ERC721-_mint-address-uint256-]]
==== `[.contract-item-name]#++_mint++#++(address to, uint256 tokenId)++` [.item-kind]#internal#

Mints `tokenId` and transfers it to `to`.

WARNING: Usage of this method is discouraged, use {_safeMint} whenever possible

Requirements:

- `tokenId` must not exist.
- `to` cannot be the zero address.

Emits a {Transfer} event.

[.contract-item]
[[ERC721-_burn-uint256-]]
==== `[.contract-item-name]#++_burn++#++(uint256 tokenId)++` [.item-kind]#internal#

Destroys `tokenId`.
The approval is cleared when the token is burned.
This is an internal function that does not check if the sender is authorized to operate on the token.

Requirements:

- `tokenId` must exist.

Emits a {Transfer} event.

[.contract-item]
[[ERC721-_transfer-address-address-uint256-]]
==== `[.contract-item-name]#++_transfer++#++(address from, address to, uint256 tokenId)++` [.item-kind]#internal#

Transfers `tokenId` from `from` to `to`.
 As opposed to {transferFrom}, this imposes no restrictions on msg.sender.

Requirements:

- `to` cannot be the zero address.
- `tokenId` token must be owned by `from`.

Emits a {Transfer} event.

[.contract-item]
[[ERC721-_approve-address-uint256-]]
==== `[.contract-item-name]#++_approve++#++(address to, uint256 tokenId)++` [.item-kind]#internal#

Hook that is called before any token transfer. This includes minting and burning. If {ERC721Consecutive} is
used, the hook may be called as part of a consecutive (batch) mint, as indicated by `batchSize` greater than 1.

Calling conditions:

- When `from` and `to` are both non-zero, ``from``'s tokens will be transferred to `to`.
- When `from` is zero, the tokens will be minted for `to`.
- When `to` is zero, ``from``'s tokens will be burned.
- `from` and `to` are never both zero.
- `batchSize` is non-zero.

being that for any address `a` the value returned by `balanceOf(a)` must be equal to the number of tokens such
that `ownerOf(tokenId)` is `a`.

Whenever an {IERC721} `tokenId` token is transferred to this contract via {IERC721-safeTransferFrom}
by `operator` from `from`, this function is called.

It must return its Solidity selector to confirm the token transfer.
If any other value is returned or the interface is not implemented by the recipient, the transfer will be reverted.

The selector can be obtained in Solidity with `IERC721Receiver.onERC721Received.selector`.

ERC721 token with pausable token transfers, minting and burning.

Useful for scenarios such as preventing trades until the end of an evaluation
period, or having an emergency switch for freezing all token transfers in the
event of a large bug.

IMPORTANT: This contract does not include public pause and unpause functions. In
addition to inheriting this contract, you must define both functions, invoking the
{Pausable-_pause} and {Pausable-_unpause} internal functions, with appropriate
access control, e.g. using {AccessControl} or {Ownable}. Not doing so will
make the contract unpausable.

Implementation of the ERC2309 "Consecutive Transfer Extension" as defined in
https://eips.ethereum.org/EIPS/eip-2309[EIP-2309].

This extension allows the minting of large batches of tokens, during contract construction only. For upgradeable
contracts this implies that batch minting is only available during proxy deployment, and not in subsequent upgrades.
These batches are limited to 5000 tokens at a time by default to accommodate off-chain indexers.

Using this extension removes the ability to mint single tokens during contract construction. This ability is
regained after construction. During construction, only batch minting is allowed.

IMPORTANT: This extension bypasses the hooks {_beforeTokenTransfer} and {_afterTokenTransfer} for tokens minted in
batch. When using this extension, you should consider the {_beforeConsecutiveTokenTransfer} and
{_afterConsecutiveTokenTransfer} hooks in addition to {_beforeTokenTransfer} and {_afterTokenTransfer}.

IMPORTANT: When overriding {_afterTokenTransfer}, be careful about call ordering. {ownerOf} may return invalid
values during the {_afterTokenTransfer} execution if the super call is not called first. To be safe, execute the
super call before your custom logic.

_Available since v4.8._

[.contract-item]
[[ERC721Consecutive-_maxBatchSize--]]
==== `[.contract-item-name]#++_maxBatchSize++#++() → uint96++` [.item-kind]#internal#

Maximum size of a batch of consecutive tokens. This is designed to limit stress on off-chain indexing
services that have to record one entry per token, and have protections against "unreasonably large" batches of
tokens.

NOTE: Overriding the default value of 5000 will not cause on-chain issues, but may result in the asset not being
correctly supported by off-chain indexing services (including marketplaces).

[.contract-item]
[[ERC721Consecutive-_ownerOf-uint256-]]
==== `[.contract-item-name]#++_ownerOf++#++(uint256 tokenId) → address++` [.item-kind]#internal#

See {ERC721-_ownerOf}. Override that checks the sequential ownership structure for tokens that have
been minted as part of a batch, and not yet transferred.

[.contract-item]
[[ERC721Consecutive-_mintConsecutive-address-uint96-]]
==== `[.contract-item-name]#++_mintConsecutive++#++(address to, uint96 batchSize) → uint96++` [.item-kind]#internal#

Mint a batch of tokens of length `batchSize` for `to`. Returns the token id of the first token minted in the
batch; if `batchSize` is 0, returns the number of consecutive ids minted so far.

Requirements:

- `batchSize` must not be greater than {_maxBatchSize}.
- The function is called in the constructor of the contract (directly or indirectly).

CAUTION: Does not emit a `Transfer` event. This is ERC721 compliant as long as it is done outside of the
constructor, which is enforced by this function.

CAUTION: Does not invoke `onERC721Received` on the receiver.

Emits a {IERC2309-ConsecutiveTransfer} event.

[.contract-item]
[[ERC721Consecutive-_mint-address-uint256-]]
==== `[.contract-item-name]#++_mint++#++(address to, uint256 tokenId)++` [.item-kind]#internal#

See {ERC721-_mint}. Override version that restricts normal minting to after construction.

Warning: Using {ERC721Consecutive} prevents using {_mint} during construction in favor of {_mintConsecutive}.
After construction, {_mintConsecutive} is no longer available and {_mint} becomes available.

==== `[.contract-item-name]#++_afterTokenTransfer++#++(address from, address to, uint256 firstTokenId, uint256 batchSize)++` [.item-kind]#internal#

See {ERC721-_afterTokenTransfer}. Burning of tokens that have been sequentially minted must be explicit.

[.hljs-theme-light.nopadding]
```solidity
import "@openzeppelin/contracts/token/ERC721/extensions/ERC721Votes.sol";
```

Extension of ERC721 to support voting and delegation as implemented by {Votes}, where each individual NFT counts
as 1 vote unit.

Tokens do not count as votes until they are delegated, because votes must be tracked which incurs an additional cost
on every transfer. Token holders can either delegate to a trusted representative who will decide how to make use of
the votes in governance decisions, or they can delegate to themselves to be their own representative.

_Available since v4.5._

Extension of ERC721 with the ERC2981 NFT Royalty Standard, a standardized way to retrieve royalty payment
information.

Royalty information can be specified globally for all token ids via {ERC2981-_setDefaultRoyalty}, and/or individually for
specific token ids via {ERC2981-_setTokenRoyalty}. The latter takes precedence over the first.

IMPORTANT: ERC-2981 only specifies a way to signal royalty information and does not enforce its payment. See
https://eips.ethereum.org/EIPS/eip-2981#optional-royalty-payments[Rationale] in the EIP. Marketplaces are expected to
voluntarily pay royalties together with sales, but note that this standard is not yet widely supported.

_Available since v4.5._

=== `++ERC721PresetMinterPauserAutoId++` link:https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v4.8.1/contracts/token/ERC721/presets/ERC721PresetMinterPauserAutoId.sol[{github-icon},role=heading-link]

[.hljs-theme-light.nopadding]
```solidity
import "@openzeppelin/contracts/token/ERC721/presets/ERC721PresetMinterPauserAutoId.sol";
```

{ERC721} token, including:

 - ability for holders to burn (destroy) their tokens
 - a minter role that allows for token minting (creation)
 - a pauser role that allows to stop all token transfers
 - token ID and URI autogeneration

This contract uses {AccessControl} to lock permissioned functions using the
different roles - head to its documentation for details.

The account that deploys the contract will be granted the minter and pauser
roles, as well as the default admin role, which will let it grant both minter
and pauser roles to other accounts.

[.contract-item]
[[ERC721PresetMinterPauserAutoId-constructor-string-string-string-]]
==== `[.contract-item-name]#++constructor++#++(string name, string symbol, string baseTokenURI)++` [.item-kind]#public#

Grants `DEFAULT_ADMIN_ROLE`, `MINTER_ROLE` and `PAUSER_ROLE` to the
account that deploys the contract.

Token URIs will be autogenerated based on `baseURI` and their token IDs.
See {ERC721-tokenURI}.

[.contract-item]
[[ERC721PresetMinterPauserAutoId-_baseURI--]]
==== `[.contract-item-name]#++_baseURI++#++() → string++` [.item-kind]#internal#

Base URI for computing {tokenURI}. If set, the resulting URI for each
token will be the concatenation of the `baseURI` and the `tokenId`. Empty
by default, can be overridden in child contracts.

[.contract-item]
[[ERC721PresetMinterPauserAutoId-mint-address-]]
==== `[.contract-item-name]#++mint++#++(address to)++` [.item-kind]#public#

Creates a new token for `to`. Its token ID will be automatically
assigned (and available on the emitted {IERC721-Transfer} event), and the token
URI autogenerated based on the base URI passed at construction.

See {ERC721-_mint}.

Requirements:

- the caller must have the `MINTER_ROLE`.

[.contract-item]
[[ERC721PresetMinterPauserAutoId-pause--]]
==== `[.contract-item-name]#++pause++#++()++` [.item-kind]#public#

Pauses all token transfers.

See {ERC721Pausable} and {Pausable-_pause}.

Requirements:

- the caller must have the `PAUSER_ROLE`.

[.contract-item]
[[ERC721PresetMinterPauserAutoId-unpause--]]
==== `[.contract-item-name]#++unpause++#++()++` [.item-kind]#public#

Unpauses all token transfers.

See {ERC721Pausable} and {Pausable-_unpause}.

Requirements:

- the caller must have the `PAUSER_ROLE`.

[.contract-item]
[[ERC721PresetMinterPauserAutoId-_beforeTokenTransfer-address-address-uint256-uint256-]]
==== `[.contract-item-name]#++_beforeTokenTransfer++#++(address from, address to, uint256 firstTokenId, uint256 batchSize)++` [.item-kind]#internal#

[.contract-item]
[[ERC721PresetMinterPauserAutoId-supportsInterface-bytes4-]]
==== `[.contract-item-name]#++supportsInterface++#++(bytes4 interfaceId) → bool++` [.item-kind]#public#
