Parameters

Returns

grantRole

function hasRole(bytes32 role, address account) external view returns (bool)

Returns true if account has been granted role.

Parameters

Returns

initialize

function initialize(string baseURI_, string contractURI_, uint256 maxMintedTokens_, uint256 maxCopiesPerToken_) external nonpayable

Citing from OpenZeppelin docs: The initialization functions use a version number. Once a version number is used, it is consumed and cannot be reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in case an upgrade adds a module that needs to be initialized. For example: contract MyToken is ERC20Upgradeable { function initialize() initializer public { __ERC20_init("MyToken", "MTK"); } } contract MyTokenV2 is MyToken, ERC20PermitUpgradeable { function initializeV2() reinitializer(2) public { __ERC20Permit_init("MyToken"); } } TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as possible by providing the encoded function call as the _data argument to {ERC1967Proxy-constructor}. CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure that all initializers are idempotent. This is not verified automatically as constructors are by Solidity. [CAUTION] ==== Avoid leaving a contract uninitialized. An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke the {_disableInitializers} function in the constructor to automatically lock it when it is deployed: constructor() { _disableInitializers(); } ====

Initializer function. Grants DEFAULT_ADMIN_ROLE to the account that initializes the contract.

Parameters

isApprovedForAll

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

See {ERC1155Upgradeable-isApprovedForAll}.This function is overridden to add support for OpenSea's Polygon proxy accounts.See https://docs.opensea.io/docs/polygon-basic-integration

Parameters

Returns

maxCopiesPerToken

function maxCopiesPerToken() external view returns (uint256)

Returns

maxMintedTokens

function maxMintedTokens() external view returns (uint256)

Returns

mint

function mint(address to, uint256 id, uint256 amount, bytes data) external nonpayable

Creates amount tokens of token type id, and assigns them to to. Also sets the token URI if uri is not empty.See {ERC1155Upgradeable-mint}.

Parameters

mintBatch

function mintBatch(address to, uint256[] ids, uint256[] amounts, bytes data) external nonpayable

Batched version of {_mint}.See {ERC1155Upgradeable-mintBatch}.

Parameters

proxiableUUID

function proxiableUUID() external view returns (bytes32)

Implementation of the ERC1822 {proxiableUUID} function. This returns the storage slot used by the implementation. It is used to validate the implementation's compatibility when performing an upgrade. IMPORTANT: A proxy pointing at a proxiable contract should not be considered proxiable itself, because this risks bricking a proxy that upgrades to it, by delegating to itself until out of gas. Thus it is critical that this function revert if invoked through a proxy. This is guaranteed by the notDelegated modifier.

Returns

renounceRole

function renounceRole(bytes32 role, address account) external nonpayable

Revokes role from the calling account. Roles are often managed via {grantRole} and {revokeRole}: this function's purpose is to provide a mechanism for accounts to lose their privileges if they are compromised (such as when a trusted device is misplaced). If the calling account had been revoked role, emits a {RoleRevoked} event. Requirements: - the caller must be account. May emit a {RoleRevoked} event.

Parameters

revokeRole

function revokeRole(bytes32 role, address account) external nonpayable

Revokes role from account. If account had been granted role, emits a {RoleRevoked} event. Requirements: - the caller must have role's admin role. May emit a {RoleRevoked} event.

Parameters

RoleAdminChanged

event RoleAdminChanged(bytes32 indexed role, bytes32 indexed previousAdminRole, bytes32 indexed newAdminRole)

Emitted when newAdminRole is set as role's admin role, replacing previousAdminRole DEFAULT_ADMIN_ROLE is the starting admin for all roles, despite {RoleAdminChanged} not being emitted signaling this. _Available since v3.1._

Parameters

RoleGranted

event RoleGranted(bytes32 indexed role, address indexed account, address indexed sender)

Emitted when account is granted role. sender is the account that originated the contract call, an admin role bearer except when using {AccessControl-_setupRole}.

Parameters

RoleRevoked

event RoleRevoked(bytes32 indexed role, address indexed account, address indexed sender)

Emitted when account is revoked role. sender is the account that originated the contract call: - if using revokeRole, it is the admin role bearer - if using renounceRole, it is the role bearer (i.e. account)

Parameters

TransferBatch

event TransferBatch(address indexed operator, address indexed from, address indexed to, uint256[] ids, uint256[] values)

Parameters

URI

event URI(string value, uint256 indexed id)

Emitted when the URI for token type id changes to value, if it is a non-programmatic URI. If an {URI} event was emitted for id, the standard https://eips.ethereum.org/EIPS/eip-1155#metadata-extensions[guarantees] that value will equal the value returned by {IERC1155MetadataURI-uri}.

Parameters

Upgraded

event Upgraded(address indexed implementation)

Emitted when the implementation is upgraded.
