ERC1155PausableUpgradeable
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. Available since v3.1.

| ids | uint256[] | undefined |
Returns
| Name | Type | Description |
|---|---|---|
| _0 | uint256[] | undefined |

function safeBatchTransferFrom(address from, address to, uint256[] ids, uint256[] amounts, bytes data) external nonpayable
See {IERC1155-safeBatchTransferFrom}.
Parameters
| Name | Type | Description |
|---|---|---|
| from | address | undefined |
| to | address | undefined |
| ids | uint256[] | undefined |
| amounts | uint256[] | undefined |
| data | bytes | undefined |
safeTransferFrom
function safeTransferFrom(address from, address to, uint256 id, uint256 amount, bytes data) external nonpayable
See {IERC1155-safeTransferFrom}.
Parameters

|---|---|---|
| operator | address | undefined |
| approved | bool | undefined |
supportsInterface
function supportsInterface(bytes4 interfaceId) external view returns (bool)
See {IERC165-supportsInterface}.

|---|---|---|
| interfaceId | bytes4 | undefined |
Returns
| Name | Type | Description |
|---|---|---|
| _0 | bool | undefined |
uri
function uri(uint256) external view returns (string)
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.
Parameters
| Name | Type | Description |
|---|---|---|
| _0 | uint256 | undefined |
Returns
| Name | Type | Description |
|---|---|---|
| _0 | string | undefined |
