ERC721Asset

Methods

DEFAULT_ADMIN_ROLE

function DEFAULT_ADMIN_ROLE() external view returns (bytes32)

Returns

MINTER_ROLE

function MINTER_ROLE() external view returns (bytes32)

Returns

approve

function approve(address to, uint256 tokenId) external nonpayable

See {IERC721-approve}.

Parameters

balanceOf

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

See {IERC721-balanceOf}.

Parameters

Returns

baseURI

function baseURI() external view returns (string)

Returns the base URI set via {_setBaseURI}.

Returns

contractURI

function contractURI() external view returns (string)

returns contract-level-metadata, See https://docs.opensea.io/docs/contract-level-metadata

Returns

getApproved

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

See {IERC721-getApproved}.

Parameters

Returns

getRoleAdmin

function getRoleAdmin(bytes32 role) external view returns (bytes32)

Returns the admin role that controls role. See {grantRole} and {revokeRole}. To change a role's admin, use {_setRoleAdmin}.

Parameters

Returns

grantRole

function grantRole(bytes32 role, address account) external nonpayable

Grants role to account. If account had not been already granted role, emits a {RoleGranted} event. Requirements: - the caller must have role's admin role. May emit a {RoleGranted} event.

Parameters

hasRole

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

Returns true if account has been granted role.

Parameters

Returns

isApprovedForAll

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

See {IERC721-isApprovedForAll}.

Parameters

Returns

name

function name() external view returns (string)

See {IERC721Metadata-name}.

Returns

ownerOf

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

See {IERC721-ownerOf}.

Parameters

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 If the calling account had been revoked role, emits a {RoleRevoked} event.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

safeMint

function safeMint(address to, uint256 tokenId) external nonpayable

See {ERC721-_mint}.

Parameters

function safeMintBatch(address to, uint256[] tokenIds) external nonpayable

See {ERC721-_mint}. Batched version of safeMint.

Parameters

See {IERC721-safeTransferFrom}.

Parameters

safeTransferFrom

Parameters

Returns

symbol

See {IERC721Metadata-symbol}.

Returns

tokenURI

function tokenURI(uint256 tokenId) external view returns (string)

See {IERC721Metadata-tokenURI}.

Parameters

Returns

transferFrom

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

See {IERC721-transferFrom}.

Parameters

Events

Approval

event Approval(address indexed owner, address indexed approved, uint256 indexed tokenId)

Emitted when owner enables approved to manage the tokenId token.

Parameters

ApprovalForAll

event ApprovalForAll(address indexed owner, address indexed operator, bool approved)

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

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

Transfer

event Transfer(address indexed from, address indexed to, uint256 indexed tokenId)

Emitted when tokenId token is transferred from from to to.
