[.readme-notice]
NOTE: This document is better viewed at https://docs.openzeppelin.com/contracts/api/token/erc1155

This set of interfaces and contracts are all related to the https://eips.ethereum.org/EIPS/eip-1155[ERC1155 Multi Token Standard].

The EIP consists of three interfaces which fulfill different roles, found here as {IERC1155}, {IERC1155MetadataURI} and {IERC1155Receiver}.

{ERC1155} implements the mandatory {IERC1155} interface, as well as the optional extension {IERC1155MetadataURI}, by relying on the substitution mechanism to use the same URI for all token types, dramatically reducing gas costs.

Additionally there are multiple custom extensions, including:

* designation of addresses that can pause token transfers for all users ({ERC1155Pausable}).
* destruction of own tokens ({ERC1155Burnable}).

NOTE: This core set of contracts is designed to be unopinionated, allowing developers to access the internal functions in ERC1155 (such as <<ERC1155-_mint-address-uint256-uint256-bytes-,`_mint`>>) and expose them as external functions in the way they prefer.

[[IERC1155-balanceOf-address-uint256-]]
==== `[.contract-item-name]#++balanceOf++#++(address account, uint256 id) → uint256++` [.item-kind]#external#

Returns the value of tokens of token type `id` owned by `account`.

Requirements:

- `account` cannot be the zero address.

[.contract-item]
[[IERC1155-balanceOfBatch-address---uint256---]]
==== `[.contract-item-name]#++balanceOfBatch++#++(address[] accounts, uint256[] ids) → uint256[]++` [.item-kind]#external#

xref:ROOT:erc1155.adoc#batch-operations[Batched] version of {balanceOf}.

Requirements:

- `accounts` and `ids` must have the same length.

[.contract-item]
[[IERC1155-setApprovalForAll-address-bool-]]
==== `[.contract-item-name]#++setApprovalForAll++#++(address operator, bool approved)++` [.item-kind]#external#

Grants or revokes permission to `operator` to transfer the caller's tokens, according to `approved`,

Emits an {ApprovalForAll} event.

Requirements:

- `operator` cannot be the caller.

[.contract-item]
[[IERC1155-isApprovedForAll-address-address-]]
==== `[.contract-item-name]#++isApprovedForAll++#++(address account, address operator) → bool++` [.item-kind]#external#

Returns true if `operator` is approved to transfer ``account``'s tokens.

See {setApprovalForAll}.

[.contract-item]
[[IERC1155-safeTransferFrom-address-address-uint256-uint256-bytes-]]
==== `[.contract-item-name]#++safeTransferFrom++#++(address from, address to, uint256 id, uint256 value, bytes data)++` [.item-kind]#external#

Transfers a `value` amount of tokens of type `id` from `from` to `to`.

WARNING: This function can potentially allow a reentrancy attack when transferring tokens
to an untrusted contract, when invoking {onERC1155Received} on the receiver.
Ensure to follow the checks-effects-interactions pattern and consider employing
reentrancy guards when interacting with untrusted contracts.

Emits a {TransferSingle} event.

Requirements:

- `to` cannot be the zero address.
- If the caller is not `from`, it must have been approved to spend ``from``'s tokens via {setApprovalForAll}.
- `from` must have a balance of tokens of type `id` of at least `value` amount.
- If `to` refers to a smart contract, it must implement {IERC1155Receiver-onERC1155Received} and return the
acceptance magic value.

[.contract-item]
[[IERC1155-safeBatchTransferFrom-address-address-uint256---uint256---bytes-]]
==== `[.contract-item-name]#++safeBatchTransferFrom++#++(address from, address to, uint256[] ids, uint256[] values, bytes data)++` [.item-kind]#external#

xref:ROOT:erc1155.adoc#batch-operations[Batched] version of {safeTransferFrom}.

WARNING: This function can potentially allow a reentrancy attack when transferring tokens
to an untrusted contract, when invoking {onERC1155BatchReceived} on the receiver.
Ensure to follow the checks-effects-interactions pattern and consider employing
reentrancy guards when interacting with untrusted contracts.

Emits a {TransferBatch} event.

Requirements:

- `ids` and `values` must have the same length.
- If `to` refers to a smart contract, it must implement {IERC1155Receiver-onERC1155BatchReceived} and return the
acceptance magic value.

[.contract-item]
[[IERC1155-TransferSingle-address-address-address-uint256-uint256-]]
==== `[.contract-item-name]#++TransferSingle++#++(address indexed operator, address indexed from, address indexed to, uint256 id, uint256 value)++` [.item-kind]#event#

[.contract-item]
[[IERC1155-TransferBatch-address-address-address-uint256---uint256---]]
==== `[.contract-item-name]#++TransferBatch++#++(address indexed operator, address indexed from, address indexed to, uint256[] ids, uint256[] values)++` [.item-kind]#event#

Equivalent to multiple {TransferSingle} events, where `operator`, `from` and `to` are the same for all
transfers.

[.contract-item]
[[IERC1155-ApprovalForAll-address-address-bool-]]
==== `[.contract-item-name]#++ApprovalForAll++#++(address indexed account, address indexed operator, bool approved)++` [.item-kind]#event#

See {IERC1155MetadataURI-uri}.

This implementation returns the same URI for *all* token types. It relies
on the token type ID substitution mechanism
https://eips.ethereum.org/EIPS/eip-1155#metadata[defined in the EIP].

Clients calling this function must replace the `\{id\}` substring with the
actual token type ID.

[[ERC1155-_update-address-address-uint256---uint256---]]
==== `[.contract-item-name]#++_update++#++(address from, address to, uint256[] ids, uint256[] values)++` [.item-kind]#internal#

Transfers a `value` amount of tokens of type `id` from `from` to `to`. Will mint (or burn) if `from`
(or `to`) is the zero address.

Emits a {TransferSingle} event if the arrays contain one element, and {TransferBatch} otherwise.

Requirements:

- If `to` refers to a smart contract, it must implement either {IERC1155Receiver-onERC1155Received}
  or {IERC1155Receiver-onERC1155BatchReceived} and return the acceptance magic value.
- `ids` and `values` must have the same length.

NOTE: The ERC-1155 acceptance check is not performed in this function. See {_updateWithAcceptanceCheck} instead.

[.contract-item]
[[ERC1155-_updateWithAcceptanceCheck-address-address-uint256---uint256---bytes-]]
==== `[.contract-item-name]#++_updateWithAcceptanceCheck++#++(address from, address to, uint256[] ids, uint256[] values, bytes data)++` [.item-kind]#internal#

Version of {_update} that performs the token acceptance check by calling
{IERC1155Receiver-onERC1155Received} or {IERC1155Receiver-onERC1155BatchReceived} on the receiver address if it
contains code (eg. is a smart contract at the moment of execution).

IMPORTANT: Overriding this function is discouraged because it poses a reentrancy risk from the receiver. So any
update to the contract state after this function would break the check-effect-interaction pattern. Consider
overriding {_update} instead.

[.contract-item]
[[ERC1155-_safeTransferFrom-address-address-uint256-uint256-bytes-]]
==== `[.contract-item-name]#++_safeTransferFrom++#++(address from, address to, uint256 id, uint256 value, bytes data)++` [.item-kind]#internal#

Transfers a `value` tokens of token type `id` from `from` to `to`.

Emits a {TransferSingle} event.

Requirements:

- `to` cannot be the zero address.
- `from` must have a balance of tokens of type `id` of at least `value` amount.
- If `to` refers to a smart contract, it must implement {IERC1155Receiver-onERC1155Received} and return the
acceptance magic value.

xref:ROOT:erc1155.adoc#batch-operations[Batched] version of {_safeTransferFrom}.

Emits a {TransferBatch} event.

Requirements:

- If `to` refers to a smart contract, it must implement {IERC1155Receiver-onERC1155BatchReceived} and return the
acceptance magic value.
- `ids` and `values` must have the same length.

[.contract-item]
[[ERC1155-_setURI-string-]]
==== `[.contract-item-name]#++_setURI++#++(string newuri)++` [.item-kind]#internal#

Sets a new URI for all token types, by relying on the token type ID
substitution mechanism
https://eips.ethereum.org/EIPS/eip-1155#metadata[defined in the EIP].

By this mechanism, any occurrence of the `\{id\}` substring in either the
URI or any of the values in the JSON file at said URI will be replaced by
clients with the token type ID.

For example, the `https://token-cdn-domain/\{id\}.json` URI would be
interpreted by clients as
`https://token-cdn-domain/000000000000000000000000000000000000000000000000000000000004cce0.json`
for token type ID 0x4cce0.

See {uri}.

Because these URIs cannot be meaningfully represented by the {URI} event,
this function emits no events.

==== `[.contract-item-name]#++_mint++#++(address to, uint256 id, uint256 value, bytes data)++` [.item-kind]#internal#

Creates a `value` amount of tokens of type `id`, and assigns them to `to`.

Emits a {TransferSingle} event.

Requirements:

- `to` cannot be the zero address.
- If `to` refers to a smart contract, it must implement {IERC1155Receiver-onERC1155Received} and return the
acceptance magic value.

[.contract-item]

Emits a {TransferBatch} event.

Requirements:

- `ids` and `values` must have the same length.
- `to` cannot be the zero address.
- If `to` refers to a smart contract, it must implement {IERC1155Receiver-onERC1155BatchReceived} and return the

ERC1155 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 pause mechanism of the contract unreachable, and thus unusable.

```solidity
import "@openzeppelin/contracts/token/ERC1155/extensions/ERC1155Supply.sol";
```

Extension of ERC1155 that adds tracking of total supply per id.

Useful for scenarios where Fungible and Non-fungible tokens have to be
clearly identified. Note: While a totalSupply of 1 might mean the
corresponding is an NFT, there is no guarantees that no other token with the
same id are not going to be minted.

NOTE: This contract implies a global limit of 2**256 - 1 to the number of tokens
that can be minted.

CAUTION: This extension should not be added in an upgrade to an already deployed contract.

==== `[.contract-item-name]#++uri++#++(uint256 tokenId) → string++` [.item-kind]#public#

See {IERC1155MetadataURI-uri}.

This implementation returns the concatenation of the `_baseURI`
and the token-specific uri if the latter is set

This enables the following behaviors:

- if `_tokenURIs[tokenId]` is set, then the result is the concatenation
  of `_baseURI` and `_tokenURIs[tokenId]` (keep in mind that `_baseURI`
  is empty per default);

- if `_tokenURIs[tokenId]` is NOT set then we fallback to `super.uri()`
  which in most cases will contain `ERC1155._uri`;

- if `_tokenURIs[tokenId]` is NOT set, and if the parents do not have a
  uri value set, then the result is empty.
